[0005] CONNECTION BEAM, COMPONENT WITH CONNECTION BEAM AND LE I TERRACE FRAME COMBINATION
[0006] A connecting support, a component with a connecting support, and a ladder frame assembly are specified.
[0007] One task to be solved is to specify a connecting beam that is particularly stable. Another task to be solved is to specify a conductor frame assembly that is particularly efficient, for example, particularly stable.
[0008] According to at least one embodiment, the terminal carrier has a first conductor frame element. The first conductor frame element is, for example, electrically conductive. For instance, the first conductor frame element comprises a metal, such as copper, or consists of a metal. The first conductor frame element can be configured for electrical contact with a component. For example, the first conductor frame element is configured as an anode or can serve as an anode.
[0009] According to at least one embodiment, the terminal carrier has a second conductor frame element. The second conductor frame element can be electrically conductive. For example, the second conductor frame element has or consists of a metal. For example, the second conductor frame element has copper. The second conductor frame element can be configured for the electrical contact of a component. The polarity of the second conductor frame element can be different from the polarity of the first conductor frame element. For example, the second 2024PF01625 14 November 2025

[0012] The conductor frame element is configured as a cathode or can serve as a cathode. However, it is also possible that the first conductor frame element is configured as the cathode and the second conductor frame element as the anode.
[0013] According to at least one embodiment, the connecting carrier has a shaped body. The shaped body is, for example, electrically insulating. For example, the shaped body is made of a plastic, such as an epoxy, for example white or black epoxy, silicone and / or hybrid composite materials.
[0014] According to at least one embodiment of the connection carrier, the first conductor frame element and the second conductor frame element are spaced apart from each other. In other words, the first conductor frame element and the second conductor frame element are not in direct contact. In particular, the first conductor frame element can be electrically isolated from the second conductor frame element, i.e., the first conductor frame element and the second conductor frame element are not electrically connected to each other.
[0015] According to at least one embodiment of the connecting carrier, the shaped body surrounds the first ladder frame element and the second ladder frame element at least partially laterally. For example, the shaped body can surround the first ladder frame element and / or the second ladder frame element almost completely laterally.
[0016] It is possible that a top and / or a bottom surface of the first ladder frame element and / or the second ladder frame element are free of the molded body. The molded body can be flush with the 2024PF01625 in the vertical direction. November 14, 2025

[0019] Close off the top and / or bottom of the first ladder frame element and / or the second ladder frame element.
[0020] For example, the top and / or bottom surface of the first and / or second conductor frame element runs parallel or at least approximately and / or partially parallel to a main extension plane of the connecting support. A side surface of the first and / or second conductor frame element, for example, runs at least approximately transversely or perpendicularly to the main extension plane of the connecting support.
[0021] The lateral direction is, in particular, a direction parallel to, or at least approximately parallel to, the principal extension plane of the connecting beam. The vertical direction is perpendicular to the lateral direction, for example, perpendicular to, or at least approximately perpendicular to, the principal extension plane of the connecting beam.
[0022] The connecting beam can have side surfaces. In particular, a side surface of the connecting beam extends transversely or perpendicularly to the main extension plane of the connecting beam. In particular, a top and a bottom surface of the connecting beam extend at least approximately parallel to the main extension plane of the connecting beam.
[0023] According to at least one embodiment of the connecting carrier, the shaped body mechanically connects the first and second ladder frame elements. For example, the shaped body is arranged between, and in particular directly between, the first and second ladder frame elements. "Directly" means that 2024PF01625 14 November 2025
[0024] P2024 , 1125 WO N
[0025] - 4 - there is no further component between the molded body and the ladder frame elements.
[0026] According to at least one embodiment of the connecting support, the second ladder frame element surrounds the first ladder frame element laterally on at least two sides. The second ladder frame element may be curved or bent, at least in some places. It is possible for the second ladder frame element to surround the first ladder frame element on more than two sides, in particular on more than two lateral sides. For example, the second ladder frame element surrounds the first ladder frame element laterally on at least three sides. "Surrounds" in this context means, for example, that the second ladder frame element follows the first ladder frame element along a direction perpendicular or at least approximately perpendicular to each of the at least two lateral sides of the first ladder frame element. For example, "surrounds" does not necessarily mean that the second ladder frame element completely surrounds one side of the first ladder frame element.For example, the second ladder frame element surrounds two opposite sides of the first ladder frame element in a lateral direction. The second ladder frame element can at least partially enclose the first ladder frame element.
[0027] The at least two sides are, for example, side faces of the first ladder frame element, in particular an upper region of the first ladder frame element, or the at least two sides can run at least approximately parallel to side faces of the first ladder frame element. The first ladder frame element, or the upper region of the first ladder frame element, has, for example, at least four main side faces. Each 2024PF01625 14 November 2025

[0030] The main side surface of the first ladder frame element can run at least approximately parallel to a side surface of the connecting support.
[0031] It is possible that at least two side faces of the first ladder frame element are parallel to each other. For example, two of the at least three sides enclosed by the second ladder frame element are located on opposite sides of the first ladder frame element. It is possible that the second ladder frame element surrounds the first ladder frame element on at least three, for example, four, main side faces of the first ladder frame element. For example, the second ladder frame element does not completely surround the first ladder frame element on at least one, for example, two or three, main side face(s).
[0032] The first ladder frame element can have a center point, for example, a fictitious or imaginary center point. The center point of the first ladder frame element can, for example, be the centroid of the area on the top surface of the first ladder frame element. The fact that the second ladder frame element laterally surrounds the first ladder frame element on at least two sides can alternatively or additionally mean that the second ladder frame element surrounds the first ladder frame element at least 180°, for example, at least 200°, or particularly at least 240°, viewed from the center point of the first ladder frame element.
[0033] According to at least one embodiment, the connecting carrier has a first conductor frame element, a second 2024PF01625 14 November 2025

[0036] A ladder frame element and a shaped body are mounted on a frame. The first and second ladder frame elements are spaced apart from each other. The shaped body surrounds the first and second ladder frame elements laterally, at least partially, and mechanically connects them. For example, the second ladder frame element surrounds the first ladder frame element laterally on at least two sides.
[0037] Alternative connecting beams, in which the second conductor frame element does not laterally surround the first conductor frame element on at least two sides, exhibit, for example, straight separations between the first and second conductor frame elements and the molded body. In other words, such alternative connecting beams may have a straight separation between the first and second conductor frame elements that extends, for example, through the molded body. Such straight separations can create weak points under bending and / or mechanical stress and therefore lead, for example, to reduced mechanical stability of the connecting beam. For example, connecting beams with a straight separation or boundary line between the first and second conductor frame elements in a conductor frame assembly, such as a pre-molded conductor frame assembly, are susceptible to bending.Furthermore, such terminal blocks exhibit, for example, an increased susceptibility to breakage during mounting the terminal block onto another support, mounting a component onto the terminal block, or due to soldering stress. 2024PF01625 14 November 2025.

[0040] The connector, for example, features complex transitions from the conductor frame elements to the molded body. Because the second conductor frame element laterally surrounds the first conductor frame element on at least two sides, the connector can have no, or at least fewer, straight or linear predetermined breaking points. This can improve the mechanical stability of the connector. For example, the connector's susceptibility to breakage is reduced. Since the connector has improved mechanical stability, handling it can be simplified. This allows the connector to be manufactured and processed more cost-effectively. The connector can also exhibit improved reliability with respect to temperature cycles, temperature shocks, and / or soldering temperatures.Furthermore, the connector carrier can offer improved reliability and / or stability against bending due to CTE difference (coefficient of thermal expansion, abbreviated GTE).
[0041] Warpage, exhibit. Furthermore, the yield in the manufacture of the connecting carriers or in the manufacture of components with the connecting carrier can be increased by reducing or avoiding cracks and / or fractures of the connecting carrier.
[0042] According to at least one embodiment of the connecting support, the second ladder frame element has a connecting web. The connecting web can project laterally beyond a major area of the second ladder frame element. For example, the connecting web may be curved, at least in some sections. Alternatively or additionally, the connecting web may be straight, at least in some sections. The connecting web may also be referred to as a tie bar. 2024PF01625 November 14, 2025

[0044] - 8 -
[0045] The main area of the second ladder frame element serves, for example, as a mounting surface for a component. In other words, the main area of the second ladder frame element can be designed to accommodate a component. The connecting web extends, for example, from the main area of the second ladder frame element to a side face of the connecting support.
[0046] The second ladder frame element can have at least one connecting web. It is possible for the second ladder frame element to have at least four, for example five, at most four, or exactly four connecting webs. The number of connecting webs in the connecting member is determined, for example, by the number of connecting webs adjacent to the side face of the connecting member. It is possible for at least one connecting web to branch into at least two connecting webs. In other words, at least two connecting webs adjacent to the side face of the connecting member can originate from a connecting web adjacent to the main area.
[0047] For example, the connecting beam is at least approximately cuboid in shape. The connecting beam can then, for example, have exactly four faces. For example, exactly one connecting web directly abuts each of the four faces of the connecting beam and / or forms part of the respective face.
[0048] According to at least one version, the second
[0049] The ladder frame element has a recess. The first 2024PF01625 14 November 2025
[0050] P2024 , 1125 WO N
[0051] 9
[0052] The ladder frame element can be positioned within the recess of the second ladder frame element. For example, the recess may be at least partially bounded by the connecting web. The recess may have an opening. This could mean that the recess is not completely surrounded laterally by the second ladder frame element.
[0053] For example, the first ladder frame element and the second ladder frame element are nested within each other. In other words, a dividing line between the first ladder frame element and the second ladder frame element is not linear, or at least not linear in places.
[0054] According to at least one embodiment, the recess tapers in a direction away from the main area of the second conductor frame element. For example, the lateral extent of the recess decreases in a direction away from the main area. The recess may be surrounded, bounded, or defined by the connecting web, at least in some places. The recess tapers, for example, because the connecting web runs transversely to a side face of the main area of the second conductor frame element, at least in some places. In other words, the connecting web may be bent or curved, at least in some places. For example, a principal direction of extension of the connecting web forms an acute angle with the side face of the main area facing the recess.The main extension direction of the connecting web can be an imaginary straight line connecting a starting point of the connecting web adjacent to the main area of the second conductor frame with an end point of the connecting web. 2024PF01625 14 November 2025.

[0057] According to at least one embodiment, the first ladder frame element has an upper region and a lower region. The lower region may project beyond the upper region laterally in certain places. For example, the lower region only projects beyond the upper region laterally in certain places.
[0058] The upper and lower sections are arranged one above the other in the vertical direction. For example, the upper section of the first ladder frame element borders the top of the first ladder frame element. The lower section can border the bottom.
[0059] According to at least one embodiment of the connecting support, the upper region of the first ladder frame element projects laterally beyond the lower region of the first ladder frame element in certain places. It is possible that the upper and lower regions of the first ladder frame element do not align flush laterally. For example, the transition from the lower to the upper region of the first ladder frame element is at least approximately stepped.
[0060] One advantage of this design is that a more complex shape of the first conductor frame element in the vertical direction improves its anchoring in the molded body. The first conductor frame element can also exhibit increased adhesion within the molded body. This, for example, improves the tightness of the connector carrier and / or a package, such as a component with the connector carrier. For example, a fall-out 2024PF01625 14 November 2025
[0061] P2024 , 1125 WO N
[0062] 11 of the ladder frame element due to the stepped construction, in some places the lower area laterally overhangs the upper area and in some places the upper area laterally overhangs the lower area, preventing or at least reducing both on the top and bottom of the connecting carrier.
[0063] By structuring the first conductor frame, for example with semi-etched structures, and the resulting improved anchoring of the first conductor frame element in the molded body, the connecting carrier can also be made particularly dense. For example, leaks and thus the ingress or seepage of a medium can be reduced.
[0064] Alternatively or additionally, the second conductor frame element can have semi-etched structures. A semi-etched structure is created, for example, by a selective etching process in which only a portion of the material thickness is removed.
[0065] According to at least one embodiment, the shaped body is flush with a bottom surface of the first conductor frame element in the vertical direction. Alternatively or additionally, the shaped body can be flush with a top surface of the first conductor frame element. Alternatively or additionally, the shaped body can be flush with a bottom surface and / or a top surface of the second conductor frame element. This can mean that the top surface of the connector is at least partially formed by the top surfaces of the first conductor frame element and / or the second conductor frame element. It is also possible that the bottom surface of the connector is at least partially formed by 2024PF01625 14 November 2025
[0066] P2024 , 1125 WO N
[0067] - 12 - the undersides of the first conductor frame element and / or the second conductor frame element are formed. The connecting carrier is, for example, a QFN (Quad Flat No Leads) carrier.
[0068] According to at least one embodiment of the connector carrier, the first and / or the second conductor frame element features a solder control structure. This solder control structure may, for example, have a recess in a lower area of the first and / or the second conductor frame element. The solder control structure may be directly adjacent to a side face of the connector carrier. A solder control structure is, for example, a specially designed area that allows targeted control of the quality and progress of the soldering process. Such solder control structures can be used to ensure that the solder flows properly, that the connections are reliably made, and that the solder joints can be visually or metrologically inspected.
[0069] According to at least one embodiment, the connection carrier has at least three conductor frame elements. These at least three conductor frame elements are, for example, spaced apart from each other. For example, the connection carrier is designed to mechanically support and / or electrically contact at least two components, for example, at least three components. It is possible that a maximum of one component is arranged on a conductor frame element. Alternatively, at least two components can be arranged on a common conductor frame element. The connection carrier is, for example, a 2024PF01625 dated November 14, 2025.

[0073] According to at least one embodiment of the connecting carrier, a coating is arranged on at least one side surface of the first conductor frame element and / or the second conductor frame element. The side surface of the first conductor frame element and / or the second conductor frame element can, at least in some places, run transversely or perpendicularly to a principal extension plane of the connecting carrier.
[0074] The coating is, for example, located between the first conductor frame element and the molded body. Alternatively or additionally, the coating can be located between the second conductor frame element and the molded body. The coating may contain or consist of silver. The coating may be rough. For example, the coating may be a rough silver (Ag) plating. The coating is designed, for example, to improve a connection, such as a mechanical anchoring, between the first and / or second conductor frame element and the molded body.

[0088] Ladder frame element and a second ladder frame element arranged at a distance from the first ladder frame.
[0089] According to at least one embodiment, the second ladder frame element surrounds the first ladder frame element laterally on at least two sides.
[0090] According to at least one embodiment, the ladder frame assembly has a plurality of connecting webs that link the second ladder frame element of one ladder frame to the second ladder frame elements of adjacent ladder frames. The connecting webs can, in particular after the ladder frames have been separated, each be encompassed by the second ladder frame element. This can mean that the second ladder frame element of one ladder frame is directly connected to the second ladder frame elements of adjacent ladder frames.
[0091] According to at least one embodiment, the ladder frame assembly comprises a plurality of regularly arranged ladder frames, each ladder frame having a first ladder frame element and a second ladder frame element spaced apart from the first ladder frame element, and the second ladder frame element laterally surrounding the first ladder frame element on at least two sides. The ladder frame assembly has, for example, a plurality of connecting webs. The plurality of connecting webs can connect the second ladder frame element of one ladder frame to the second ladder frame elements of adjacent ladder frames. For example, the ladder frame assembly is formed in one piece and / or as a continuous structure. 2024PF01625 November 14, 2025

[0094] According to at least one embodiment of the conductor frame assembly, the first conductor frame element of a conductor frame is connected to the second conductor frame element of an adjacent conductor frame. In particular, a solder control structure of the first conductor frame element can be directly connected to a solder control structure of the second conductor frame element.
[0095] According to at least one embodiment, the second ladder frame element of a ladder frame has a recess, and the first ladder frame element of the ladder frame is arranged in the recess of the second ladder frame element.
[0096] According to at least one embodiment, at least one second ladder frame element has four connecting webs that connect the second ladder frame element to the four directly adjacent second ladder frame elements. "Directly adjacent" can mean that a side face of the second ladder frame element faces a side face of the directly adjacent second ladder frame element. In particular, "directly adjacent" can mean that the second ladder frame elements are not diagonally adjacent.
[0097] According to at least one embodiment of the conductor frame assembly, the connecting webs in the separation area run at least approximately perpendicular to a principal extension direction of the separation area. Along the separation area or areas, the conductor frame assembly is, for example, separated into conductor frames. For example, connecting carriers or components are manufactured within the conductor frame assembly. In this case, for example, a large number of connecting carriers or 2024PF01625 14 November 2025
[0098] P2024 , 1125 WO N
[0099] - 17 - A large number of components are separated into individual terminals or components along the separation areas. For example, the conductor frame assembly is separated using saws. By using connecting webs that run at least approximately perpendicular to a saw surface or edge, damage and / or increased wear of the saw blade during separation can be prevented or reduced. Connecting webs that run perpendicular to the saw edge or a saw cut in places can also increase the mechanical stability of the terminal against bending stress. Additionally, the perpendicular arrangement minimizes the exposed copper edge, for example, of the connecting web, in its horizontal extent. With angled connecting webs, the exposed copper edge is, for example, disadvantageously wider.
[0100] For example, all connecting webs of the conductor frame assembly in the separation area can run at least approximately perpendicularly, in particular perpendicularly to a principal extension direction of the separation area, or at least approximately perpendicularly or perpendicularly to a principal extension direction of one of the separation areas. It is possible that the connecting web runs parallel to another principal extension direction of a further separation area. The further separation area can run at least approximately perpendicularly to the separation area.
[0101] The main direction of extension of the connecting web in the separation area can, for example, run perpendicular to a boundary surface between the connecting web and the separation area. The boundary surface can be a cross-sectional area of the 2024PF01625 14 November 2025

[0121] Figure 1 shows a top view of a conductor frame 5 or a connecting support 1 according to an exemplary embodiment. In particular, Figure 1 shows a top view of a top surface 10 of the connecting support 1. The connecting support 1 has the conductor frame 5. Additionally, as indicated in Figure 1, the connecting support 1 may include a shaped body 4. For example, the connecting support 1 differs from the conductor frame 5 by the presence of the shaped body 4. 2024PF01625 November 14, 2025
[0122] P2024 , 1125 WO N

[0124] The connecting support 1 has a first ladder frame element 2 and a second ladder frame element 3. The first ladder frame element 2 and the second ladder frame element 3 are spaced apart from each other. The second ladder frame element 3 can laterally surround the first ladder frame element 2 on at least two sides. It is possible that the second ladder frame element 3 laterally surrounds the first ladder frame element 2 on at least 2.5 sides or at least three sides. In other words, the second ladder frame element 3 completely surrounds the first ladder frame element 2 laterally on two sides and partially on another side, in particular only partially or only in certain places. This can also mean that the second ladder frame element 3 laterally surrounds the first ladder frame element 2 on at least two sides and a fraction of another side.
[0125] The top surface 10 of the connecting carrier 1, for example, comprises a top surface 24 of the first conductor frame element 2 and a top surface 37 of the second conductor frame element 3. The area of the top surface 24 of the first conductor frame element 2 can be smaller than the area of the top surface 37 of the second conductor frame element 3.
[0126] The second ladder frame element 3 has at least one connecting web 33, in particular four connecting webs 33, and a main area 34. The main area 34 is, for example, at least approximately rectangular in plan view. It is possible that the main area 34 has a structure in plan view, for example, indentations, as shown here. The main area 34 can be configured to accommodate at least one component 60. 2024PF01625 November 14, 2025

[0129] For example, main area 34 is a chip mounting area. The size of main area 34 can be adapted to the size of component 60.
[0130] The first and / or second conductor frame element 2, 3 can have a side surface. The side surface of the first conductor frame element 2 and / or the second conductor frame element 3 extends, for example, at least partially transversely or perpendicularly to a main extension plane of the connecting carrier 1.
[0131] The connecting web 3 projects beyond the main area 34, for example, in a lateral direction x, y. The connecting web 33 can be curved, at least in some places. This can mean that a central axis of the connecting web 33 is bent or curved. The central axis of the connecting web 33 can form an acute angle, at least in some places, with the side surface of the second conductor frame element 2 adjacent to the recess 35. The recess 35 can be bounded or defined by the side surface of the second conductor frame element 2 and by the at least one connecting web 33.
[0132] It is possible that at least one connecting web 33 has a branch into at least two connecting webs 33. It is possible that one connecting web 33, in the view shown here the connecting web 33 running to the right of the first conductor frame element 2, has a section that does not extend to a side face of the terminal carrier 1. In other words, a section of a connecting web 33 can terminate within a component edge of a component 6 with the terminal carrier 1. This can, for example, prevent a short circuit through a 2024PF01625 14 November 2025

[0135] Smearing of the material of the connecting web 33 during a subsequent cutting, for example by sawing, is prevented.
[0136] Alternatively, not shown, the connecting web 33 running to the right of the first ladder frame element 2 in the view shown here can be designed analogously, for example in reverse, to the connecting web 33 running to the left of the first ladder frame element 2. This can mean that in a ladder frame assembly 50, for example, the second ladder frame element 3 is connected to an adjacent ladder frame element 3 by at least two connecting webs 33, 52.
[0137] For example, the second ladder frame element 3 surrounds the first ladder frame element 2 on the side of the first ladder frame element 2 facing the main area 34. Alternatively or additionally, the second ladder frame element 3 can surround the first ladder frame element 2 on the side of the first ladder frame element 2 facing away from the main area 34. Alternatively or additionally, the second ladder frame element 3 can surround the first ladder frame element 2 on at least one side that is at least approximately perpendicular to the side facing the main area 34.
[0138] For example, the first conductor frame element 2 is arranged in the recess 35 of the second conductor frame element 3. The shaped body 4 can at least partially surround the first conductor frame element 2 and the second conductor frame element 3 laterally and mechanically connect them. The shaped body 4 is, for example, made of or comprises an electrically insulating material. 2024PF01625 November 14, 2025

[0141] For example, the recess 35 of the second ladder frame element 3 is completely filled with the first ladder frame element 2 and the molded body 4.
[0142] The recess 35 tapers in a direction away from the main area 34 of the second conductor frame element 3. In other words, the lateral extension of the recess 35 in a direction that runs at least approximately parallel to the side surface of the second conductor frame element 3 facing the recess 35 decreases with increasing distance from the main area 34. Alternatively or additionally, the recess 35 is tapered, for example, by the fact that the central axis of the connecting web 33 bounding the recess 35 runs at least partially at an acute angle to the side surface of the second conductor frame element 3 facing the recess 35.
[0143] The first conductor frame element 2 has a solder control structure 20. The second conductor frame element 3 has a second solder control structure 30. The solder control structures 20, 30 are directly adjacent to side faces, in particular outer faces, of the connector carrier 1. The solder control structure 20, for example, is adjacent to a first side face of the connector carrier 1. The second solder control structure 30 can then, as shown here, be adjacent to the side face of the connector carrier 1 opposite the first side face. By means of the solder control structures 20, 30, for example, melting, such as complete melting, of solder or soldering material can be monitored when applying or soldering the connector carrier to another carrier. It is also possible that the solder control structures 20, 30 are configured to perform a 2024PF01625 14 November 2025

[0146] To improve the connection of the conductor frame elements 2, 3 with the molded body 4. For example, the solder control structures 20, 30 are formed in one piece with the respective conductor frame element 2, 3.
[0147] The first conductor frame element 2 has an upper region 22 and a lower region 21. The lower region 21 projects laterally beyond the upper region 22 in certain areas. As shown here, the lower region 21 of the first conductor frame element 2 projects laterally beyond the upper region 22 of the first conductor frame element 2, at least partially, on the side facing the main region 34 of the second conductor frame element 3. The lower region 21 projects laterally beyond the upper region 22 in the area of the solder control structure 20, as shown here. This allows the upper region 22 to have, for example, a small lateral extension in the area of the solder control structure 20. This, in turn, allows for a greater taper of the recess 35 away from the main region 34.
[0148] It is also possible that the upper region 22 of the first ladder frame element 2 project beyond the lower region 21 of the first ladder frame element 2 in the lateral direction x, y at certain points. For example, the upper region 22 projects beyond the lower region 21 at least on two opposite sides. For example, as shown here, the upper region 22 projects beyond the lower region 21 on at least one side, for example on two sides, in a direction at least approximately parallel to the side surface of the second ladder frame element 3 facing the recess 35.
[0149] Contrary to what is shown, it is also possible that the connecting carrier 1 has at least three conductor frame elements 2, 3 2024PF01625 14 November 2025
[0150] P2024 , 1125 WO N
[0151] - 25 - has . The at least three conductor frame elements 2 , 3 can be spaced apart from each other. For example, the connection carrier 1 is then configured to receive and / or electrically contact at least two components 60. Each component 60 can be arranged on a conductor frame element 2 , 3. For example, each component 60 is uniquely assigned to a conductor frame element 2 , 3.
[0152] A coating 41 can be arranged on at least one side surface of the first conductor frame element 2 and / or the second conductor frame element 3.
[0153] Figure 2 shows another schematic view of the connecting carrier 1 or ladder frame 5 shown in Figure 1.
[0154] Figure 2 shows that the upper region 22 of the first ladder frame element 2 is arranged vertically z above the lower region 21 of the first ladder frame element 2. Similarly, an upper region 32 of the second ladder frame element 3 is arranged vertically z above a lower region 31 of the second ladder frame element 3. In other words, the upper regions 22, 32 follow the lower regions 21, 31 in the vertical direction z, specifically directly after.
[0155] The connecting web 33 or connecting webs 33 are, for example, arranged in the upper region 32 of the second ladder frame element 3. The lower region 31 of the second ladder frame element 3 is, for example, free of connecting webs 33. 2024PF01625 14 November 2025

[0158] The solder control structures 20, 30 each have a recess in a lower region 21, 31 of the first conductor frame element 2 and / or the second conductor frame element 3. The recess borders, for example, directly on a side surface and a bottom surface 11 of the terminal carrier. The recess is not filled with any material from the molded body 4.
[0159] In a cross-section, the shaped body 4 between the first ladder frame element 2 and the second ladder frame element 3 is, for example, at least approximately Z-shaped.
[0160] Figure 3 shows a schematic top view of the underside 11 of the terminal carrier 1 shown in Figures 1 and 2. The underside 11 is opposite the top side 10 of the terminal carrier 1. The lower region 31 of the second conductor frame element 3, for example, has a smaller extension in the lateral direction x, y than the upper region 32 of the second conductor frame element 3, particularly in the main region 34. For example, the lower region 31 projects beyond the upper region 32 in the lateral direction x, y in the region of the second solder control structure 30.
[0161] Figures 4, 5, and 6 show further schematic views of the connector carrier 1 shown in Figures 1 to 3. These illustrations clarify in particular the geometric design, the arrangement, and the functionality of the individual areas of the connector carrier 1, including possible semi-etched structures, contact surfaces, and solder control points 20, 30. 2024PF01625 14 November 2025

[0164] Figures 7A and 7B show schematic cross-sections through a solder control structure 20, 30 of a terminal carrier 1 according to the exemplary embodiments. The solder control structure 20, 30 of Figure 7A has a rectangular outline.
[0165] In comparison, the solder control structure 20, 30 of Figure 7B has at least an approximately trapezoidal outline in the cross-section shown here. Unlike what is shown, the solder control structure 20, 30 may have semi-etched structures and / or steps. For example, corners of the solder control structure 20, 30 may be rounded. The fact that the solder control structure 20, 30 has a trapezoidal outline may mean that the solder control structure has a smaller lateral extent in the upper region 22, 32 than in the lower region 21, 31.
[0166] This allows the connecting webs 33 of the second conductor frame element 3, located in the upper region 32 of the second conductor frame element 3, to run at a sharper angle to the side surface of the main region 34 facing the recess 35. This can mean that the connecting web 33 can have a greater curvature. It is also possible that the distance between connecting webs 33 of the second conductor frame element 3 on the side of the first conductor frame element 2 facing away from the main region 34 can be reduced by the approximately trapezoidal shape of the solder control structure 20 of the first conductor frame element 2. A minimum distance between the first conductor frame element 2 and the second conductor frame element 3 to prevent a short circuit can still be ensured by the approximately trapezoidal shape of the solder control structure 20 of the first conductor frame element 3. 2024PF01625 November 14, 2025

[0169] Figure 8 shows a schematic top view of a ladder frame assembly 50 according to an exemplary embodiment. The ladder frame assembly 50 has a plurality of regularly arranged ladder frames 5. Each ladder frame 5 can correspond to the ladder frame 5 shown in Figures 1 to 6. In particular, each ladder frame 5 has a first ladder frame element 2 and a second ladder frame element 3 spaced apart from the first ladder frame element 2. The second ladder frame element 3 surrounds the first ladder frame element 2 laterally on at least two sides. For example, the second ladder frame element 3 surrounds the first ladder frame element 2 laterally on more than two sides, for example, on at least three sides.
[0170] The ladder frame assembly 50 also has a plurality of connecting webs 33, 52. The connecting webs 33, 52 connect the second ladder frame element 3 of a ladder frame 5 to the second ladder frame elements 3 of adjacent ladder frames 5. For example, at least one second ladder frame element 3 has four connecting webs 33, 52. The four connecting webs 33, 52 connect the second ladder frame element 3 to the four directly adjacent second ladder frame elements 3.
[0171] It is also possible that at least one second ladder frame element 3 is directly connected to a perimeter 51 of the ladder frame assembly 50 via a connecting web 33, 52. In particular, each second ladder frame element 3 that is arranged directly adjacent to the perimeter 51 is connected to the perimeter 51 by at least one connecting web 33, 52. Directly adjacent means 2024PF01625 14 November 2025
[0172] P2024 , 1125 WO N
[0173] - 29 - for example, that no further second ladder frame element 3 is arranged between the ladder frame element 3 and the perimeter 51.
[0174] The first conductor frame element 2 of a conductor frame 5 is connected to the second conductor frame element 3 of an adjacent conductor frame 5 or to the perimeter 51. For example, as shown here, the first conductor frame element 2 of a conductor frame 5 is connected to the second conductor frame element 3 of the adjacent conductor frame 5, which is arranged on the side of the first conductor frame element 2 facing away from the main area 34 of the second conductor frame element 3 of the conductor frame 5. For example, the first conductor frame element 2 does not have a connecting web. For example, the first conductor frame element 2 is connected to the perimeter 51 or to a second conductor frame element 3 of an adjacent conductor frame 5 via the solder control structure 20. In particular, the solder control structure 20 can be connected to or merge into the solder control structure 30 of the second conductor frame element 3. The conductor frame assembly 50 can be formed in one piece or as a continuous structure.
[0175] To separate the conductor frame assembly 50 into conductor frames 5, indicated by the dashed boxes, the conductor frame assembly 50 can, for example, be cut in separation areas. The separation areas are located, for example, between adjacent conductor frames 5. The connecting webs 52 run at least approximately perpendicular to a principal extension direction of the respective separation area in the separation areas.

In particular, the second conductor frame element 3 in the conductor frame assembly 50 can be connected to the second conductor frame element 3 of the adjacent conductor frame 5, which is connected to the first conductor frame element 2 via the solder control structures 20, 30, by at least two, and in particular exactly two, connecting webs 33. This can mean that an outer surface of a single terminal carrier 1 has a solder control structure 20 and two connecting webs 33. The connecting webs 33 are then, for example, arranged on opposite sides of the solder control structure 20.
[0179] Figure 9 shows another schematic top view of a ladder frame assembly 50. The ladder frame assembly 50 shown in Figure 9 differs from the ladder frame assembly shown in Figure 8, for example, in that the ladder frame assembly 50 has a shaped body 4. The shaped body 4 completely fills, for example, the spaces between the ladder frame assembly 50. For example, the shaped body 4 completely surrounds exposed side surfaces of the first ladder frame elements 2 and the second ladder frame elements 3 laterally. The shaped body can be flush with the first and / or second ladder frame elements 2, 3 in the vertical direction z. Alternatively, not shown, it is possible for the shaped body 4 to project beyond the first and / or second ladder frame elements 2, 3 in the vertical direction z on at least one side.For example, the shaped body 4 projects beyond the top surface 24, 37 of the first and / or second conductor frame element 2, 3 and forms, for example, a cavity for a component 60. 2024PF01625 14 November 2025.

[0182] Figure 10 shows a schematic top view of a ladder frame 5 according to an exemplary embodiment. The ladder frame 5 can be a ladder frame 5 from the ladder frame assembly 50 shown in Figure 8, or the ladder frame 5 shown in Figure 1, or the ladder frame 5 encompassed by the connecting carrier 1. In particular, Figure 10 shows a top view of the upper surfaces 24, 37 of the first ladder frame element 2 and the second ladder frame element 3.
[0183] The second ladder frame element 3 surrounds the first ladder frame element 2, for example, in an approximately U-shape. This can mean that the recess 35 of the second
[0184] The ladder frame element 3 is at least approximately U-shaped. In particular, the "U" of the recess 35 can taper at the opening. The recess 35 has, for example, a curved border. This can mean that the border of the recess 35 is free of acute angles. In other words, the side surfaces of the second ladder frame element 3 that bound the recess 35 are, for example, curved at least in places.
[0185] The dashed line indicates the course of a boundary line between the first and second conductor frame elements 2, 3. The boundary line is not linear or straight, but curved and / or bent. In a connecting beam 1 with the conductor frame 5, the boundary line does not extend from one side face of the connecting beam 1 to an opposite side face of the connecting beam 1. Instead, the boundary line extends from one side face of the connecting beam 1 to the same side face of the connecting beam 1. 2024PF01625 November 14, 2025
[0186] P2024 , 1125 WO N
[0187] - 32 -
[0188] For example, the intersection points of the boundary line and the side surface are located close together. This allows the connecting beam 1 to exhibit improved or increased fracture stability.
[0189] The curved boundary line prevents or at least reduces points of attack for linearly oriented force vectors. With curved and / or complex geometries, such as a curved boundary line, the formation of fracture nuclei or the propagation of fractures is hindered. This means that the formation of linearly propagating force vectors, which can lead to fracture nuclei in the connecting beam 1 or in the shaped body 4 of the connecting beam 1 and / or to cracks, especially linear cracks in the shaped body 4, can be avoided or at least reduced.
[0190] Figure 11 shows a schematic top view of a ladder frame 5 according to a comparative example. In particular, Figure 11 shows a bottom surface 23 of a first ladder frame element 2 and a bottom surface 46 of a second ladder frame element 3, or a top view of a bottom surface 11 of a connecting support 1. In contrast to the ladder frame 5 or connecting support 1 shown in Figure 10, the ladder frame 5 of Figure 10 has a multiple of connecting webs 33. For example, both the first ladder frame element 2 and the second ladder frame element 3 have five connecting webs 33. Due to the multiple of connecting webs 33, the connecting support 1 shown here has, for example, low mechanical stability in a finished component 6. 2024PF01625 November 14, 2025

[0193] The dashed line shown here indicates a boundary line between the first ladder frame element 2 and the second ladder frame element 3. In the comparative example shown here, the boundary line is linear. Specifically, the boundary line extends from one side face of the connecting beam 1 to the opposite side face of the connecting beam 1. This linear boundary line leads, for example, to a predetermined breaking point under bending loads and / or mechanical stress.
[0194] In the comparative example shown here, the first ladder frame element still has no structuring in the vertical direction z, with the upper area alternately exceeding the lower area and vice versa.
[0195] Figure 12 shows a schematic view of a lead frame 1. The lead frame 1 can include the first lead frame element 2 and second lead frame element 3 shown in Figure 10, as well as the molded body 4. The connecting webs 33 are flush with the side surfaces of the lead frame 1 and with the top surface 10 of the lead frame 1. The molded body 4 is flush in the vertical direction z with the bottom surface 23, 36 and the top surface 24, 37 of the lead frame elements 2, 3. The lead frame 1 can be a so-called "flat premolded leadframe".
[0196] Figure 13 shows a schematic view of the rear side 11 of the connecting carrier 1 shown in Figure 12.

[0200] The ladder frame 5 shown in Figure 11 comprises the first ladder frame element 2 and the second ladder frame element 3. The ladder frame elements 2 and 3 are embedded in a molded body 4. To prevent the ladder frame elements 2 and 3 from falling out, it is necessary, for example, that the connecting webs 33 on the top surface 10 of the connecting support 1 do not terminate flush with the molded body 4.
[0201] Figure 15 shows a conductor frame 5. Figures 15 to 18 also explain in more detail a method for manufacturing a component 6. In the process step shown in Figure 15, the conductor frame 5 is provided. The conductor frame 5 can, in particular, be provided in a conductor frame assembly 50. The conductor frame 5 shown here can, for example, be manufactured from a metal plate by etching. Before treating the metal plate with an etching acid, etching masks are arranged on a top and a bottom surface of the metal plate. A thickness in a direction perpendicular to a principal plane of extension of the metal plate is, for example, at least 50 pm, at least 200 pm, or at least 400 pm. Semi-etched structures, for example, can be produced using the etching masks. During etching, the first conductor frame element 2 is formed spaced apart from the second conductor frame element 3.
[0202] Figure 16 shows a subsequent process step in which the connecting carrier 1 is produced by arranging the molded body 4. For example, the molded body 4 is arranged using an injection molding process.
[0203] Subsequently, as shown in Figure 17, a component 60 is placed on the second conductor frame element 3, for example on the upper 2024PF01625 14 November 2025
[0204] P2024 , 1125 WO N
[0205] - 35 -
[0206] Area 32, in particular on the main area 34 of the second conductor frame element 3. The component 60 can be a sensor or an emitter, for example a light-emitting diode (LED), or comprise one or more such. The component 60 can have a main body 62. The main body 62 is configured, for example, for generating or detecting electromagnetic radiation. A conversion layer 63 can be arranged on the side of the main body 62 facing away from the terminal carrier 1. An adhesive 64, for example a solder and / or an adhesive, can be arranged between the component 60 and the terminal carrier 1. The adhesive 64 is, for example, electrically conductive. The component 60 can be electrically connected to the second conductor frame element 3. For example, the component 60 can be electrically connected to the first conductor frame element 2 by means of a wire bond 61.It is possible that the conversion layer 63 is already arranged on or connected to the main body 62 when the main body 62 is applied. Alternatively, the conversion layer 63 can be applied to the side of the main body 62 facing away from the connection carrier 1 only after the main body 62 has been applied to the second conductor frame element 3, for example, after the wire bond 61 has been arranged.
[0207] Figure 18 shows a further process step for manufacturing a component 6 or a component 6 with a terminal carrier 1. For example, after arranging and electrically contacting the component 60, an encapsulation 40 is applied which at least partially surrounds or transforms the terminal carrier 1, the component 60 and / or the wire bond 61. The conversion layer 63 is 2024PF01625 14 November 2025
[0208] P2024 , 1125 WO N
[0209] - 36 - for example, only laterally surrounded by the encapsulation 40. In other words, the side of the conversion layer 63 facing away from the connecting carrier 1 can be free of the encapsulation 40. For example, the encapsulation 40 is an injection molding compound applied by means of an injection molding process. Alternatively, the encapsulation 40 can be arranged by casting or film-assisted molding. The
[0210] Encapsulation 40 can be electrically insulating. In particular, encapsulation 40 may contain plastics, for example silicones, such as white silicone, or epoxy resins. It is possible that encapsulation 40 may also contain radiation-absorbing, radiation-scattering, and / or reflective materials.
[0211] The process steps described in conjunction with Figures 15 to 18 can be carried out simultaneously for a large number of components 6 in an assembly, for example, a component assembly or a conductor frame assembly 50. Subsequently, the assembly can be separated into individual components 6. For this purpose, for example, the solder control structures 20, 30, the connecting webs 52, the molded body 4, and / or the encapsulation 40 are cut by sawing along the separation area. The connecting webs 52 of the conductor frame assembly 52 are, for example, cut to form the connecting webs 33 of the second conductor frame elements 3.
[0212] Figures 19 and 20 show alternative process steps for manufacturing a component 6. The process step shown in Figure 19, for example, directly follows the process step shown in Figure 15. This can mean that the component 60 is prepared before a mold body is placed on the mold. 2024PF01625 14 November 2025
[0213] P2024 , 1125 WO N
[0214] - 37 - is arranged on the conductor frame 5 and / or is electrically connected to it.
[0215] The subsequent process step, Figure 20, essentially corresponds to the process step described in Figure 18. In contrast, the component 6 in Figure 20 does not comprise a molded body 4 and an encapsulation 40. Rather, the encapsulation 40 acts as the molded body 4. In the process described in Figures 19 and 20, the molded body 4 and the encapsulation 40 are produced in a single step as the encapsulation 40. The first ladder frame element 2 and the second ladder frame element 3 are then mechanically connected to each other in the component 6 by means of the encapsulation 40.
[0216] Figure 21 shows a schematic section of a ladder frame assembly 50. The four connecting webs 33, which link one ladder frame 5 to the four directly adjacent ladder frames 5, connect all the ladder frames 5 in a straight line to the perimeter 51 (not shown) of the ladder frame assembly 50. This prevents or at least reduces deformation, such as twisting of individual ladder frames 5 or movement of columns and rows of the ladder frames 5 towards each other. For example, this eliminates the need for the first ladder frame element 2 to have connecting webs. Despite the straight connection of all ladder frames 5 to the perimeter 51, the curved connecting webs 33 provide flexibility that prevents or reduces warping of the ladder frame assembly 50 in critical areas.For example, a ladder frame 5 of the ladder frame assembly 50 or the ladder frame assembly 50 may warp in non-critical areas 2024PF01625 14 November 2025.
[0217] P2024 , 1125 WO N
[0218] - 38 - and / or deform. This allows stress caused by thermal strain to be reduced. This stress reduction, for example, ensures a reduced warpage of the conductor frame assembly 50. The flexible elements, for example, the bent or curved connecting webs 33, can be arranged, for example, only in functionally non-critical areas of the conductor frame 5 or the component 6. This prevents or at least reduces deformation of the two solder pads, for example, of the first conductor frame element 2 and the main area 34 of the second conductor frame element 3. The stress is thus reduced, for example, only by the connecting webs 33, 52, for example, by spring-loaded connecting webs 33, 52. This simplifies and optimizes subsequent process steps, such as the arrangement of the component 60 and the arrangement of the wire bond 61.For example, line LI runs in a serpentine pattern. In the lateral direction x, which corresponds to a principal extension direction of line LI, the ladder frame assembly 50 can be more flexible than in the lateral direction y, which corresponds to a principal extension direction of line L2.
