Description

Technical Field

[0001] The utility model relates to the technical field of cleaning component carriers, and more specifically, to a cleaning frame used in a cleaning device for component carriers. Background Art

[0002] As electronic components become increasingly miniaturized and the number of electronic components that can be installed on component carriers continues to increase, the market is also constantly raising its requirements for component carriers. In order to further achieve the refinement of electronic products, the size specifications of component carriers are not only required to be reduced, but also because there are more and denser circuits and pads on component carriers with smaller size specifications, higher requirements are also placed on the cleaning accuracy of component carriers. In the prior art, component carriers with too small size specifications (such as: when the length of the component carrier is less than 100 mm and the width is less than 50 mm) are very easy to displace during the flushing process, causing friction between the surface of the component carrier and the blade roller of the high-pressure flushing line, and even causing adjacent component carriers to collide with each other during the high-pressure flushing process, thereby causing greater wear and tear and reducing the yield of the product.

[0003] Figure 6 as well as Figure 7 An example from the prior art is shown. Figure 6 The component carrier 201 of conventional size adapted to the high-pressure washing line 200 is shown. Its position does not change before and after high-pressure washing. The surface of the component carrier 201 will not rub against the blade roller of the high-pressure washing line 200, and adjacent component carriers 201 will not collide with each other, thereby ensuring the production quality of the component carrier 201. Figure 7 It shows that the small size is not suitable for the component carrier 202 of the high-pressure washing line 200, and its position is changed after high-pressure washing. The surface of the component carrier 202 will rub against the blade roller part of the high-pressure washing line 200, and the adjacent component carriers 202 will directly collide, and the production quality of the component carrier 202 cannot be guaranteed. An existing solution is to reduce the number of component carriers washed each time in the high-pressure washing line, increase the distance between them, and thus reduce the possibility of collision and scratching between component carriers, but this method reduces production efficiency.

[0004] In addition, when the component carrier is washed under high pressure, there is a possibility that the component carrier may be broken or damaged due to the excessive impact force generated by the washing, further reducing the yield of the product. Utility Model Content

[0005] The purpose of the utility model is to provide a cleaning frame for a component carrier cleaning device, which can fix component carriers with smaller specifications and sizes during high-pressure cleaning, and can also reduce the excessive impact force on the surface of the component carrier during flushing. It can also clean a large number of component carriers at the same time, thereby improving production efficiency.

[0006] According to an exemplary embodiment of the utility model, a cleaning frame for a cleaning device for a component carrier is provided, comprising: a plurality of openings, the openings being configured to fix a component carrier; wherein at least one slot body is provided between at least two openings, which is configured to flow a cleaning medium; and the length of at least one slot body extending along the plane of the cleaning frame is greater than the length of each of the at least two openings. Through the cleaning frame, a plurality of component carriers of smaller sizes can be fixed in the openings of the cleaning frame, so that they do not change their positions during the cleaning process, and thus do not generate undesirable collisions and frictions, which can greatly improve the yield of the product. At the same time, the slot body provided between the two openings can flow the cleaning medium, that is, during the high-pressure washing process, the high-pressure water flow can flow from one surface of the cleaning frame to another opposite surface through the slot body. In addition, the length of the slot body is greater than the length of the opening, which can further improve the efficiency of the flow of the cleaning medium, thereby reducing the pressure of the high-pressure water flow on the entire cleaning frame and the surface of the component carrier placed therein, which can effectively prevent the possibility of the component carrier being broken or damaged during the high-pressure washing process.

[0007] According to another exemplary embodiment of the utility model, a plurality of openings are arranged in an array; the lateral distance between the centers of at least two openings is different from the longitudinal distance between the centers of the two openings. The openings arranged in an array can fix the component carrier in a neat form in the cleaning frame, which is not only easy to manage production, but also can ensure that the flushing pressure generated during the cleaning process is evenly distributed, thereby further reducing the possibility of the component carrier being broken or damaged during the high-pressure flushing process. The lateral distance between the centers of at least two openings and the longitudinal distance between the centers of the two openings can be adjusted according to actual needs, such as achieving a compact arrangement while ensuring the structural stability of the cleaning frame, thereby improving the cleaning efficiency. In another possible embodiment, the lateral distance between the centers of at least two openings and the longitudinal distance between the centers of the two openings can also be the same, which can ensure that the openings are arranged more compactly in the cleaning frame, thereby improving the cleaning efficiency.

[0008] According to another exemplary implementation method of the utility model, at least one slot body extends between the two openings and corresponds to the same plane of the openings, and extends from one end of the frame to the other end of the frame. In this embodiment, the length of the slot body is longer, but its length is less than the extension distance from one end to the other end of the cleaning frame. While ensuring the structural stability of the cleaning frame, the efficiency of the flow of the cleaning medium can be further improved.

[0009] According to another exemplary implementation method of the utility model, the width of at least one slot is smaller than the lateral distance between at least two openings, or the width of at least one slot is smaller than the longitudinal distance between at least two openings. The slot is arranged between the long sides / short sides of two adjacent openings, and the slot is not directly connected to any opening, so that the structure of the cleaning frame can be ensured to be stable.

[0010] According to another exemplary implementation method of the present invention, the opening is a rectangular opening.

[0011] According to another exemplary implementation method of the utility model, the opening is a square opening. The shape of the opening can be adjusted according to the size of the component carrier to be cleaned, and a suitable opening shape can further ensure the cleaning efficiency and the stability of the overall structure.

[0012] According to another exemplary implementation method of the utility model, an arc-shaped opening is provided along the corresponding two sides of the rectangular opening, and the arc-shaped opening is configured to / suitable for the passage of the clamp. Whether before or after cleaning (especially after the cleaning is completed), the clamp is required to put in / take out the component carrier, and the arc-shaped opening is suitable for the passage of the clamp, so that when the clamp takes out the component carrier, it only needs to contact the frame area of ​​the component carrier with the clamp, without directly contacting the circuit area where the circuit, pad, etc. are set in the component carrier, which can reduce the contamination of the surface of the component carrier by foreign matter (such as dust, etc.) on the clamp, thereby further improving the product yield. The clamp can be a mechanical arm, for example, a small mechanical arm is used to pass through the arc-shaped opening, clamped on the two side frame areas of the component carrier to take out the component carrier, so that there is no need to contact the circuit area where the circuit, pad, etc. are set in the component carrier, and the particles (such as dust) attached to the small mechanical arm are prevented from contaminating the component carrier, thereby reducing the product yield. Similarly, the operator can also pass his fingers through the arc-shaped opening and take out the component carrier by gripping the frame area of ​​the component carrier with his fingers, thereby preventing the operator's sweat or fingerprints from contaminating the component carrier and reducing the yield of the product. In addition, during the cleaning process, the arc-shaped opening can also be used to flow the cleaning medium to reduce the flushing pressure on the cleaning frame and the surface of the component carrier. In another embodiment, when the automation construction is complete, the arc-shaped opening is configured to be / suitable for a robot arm or other clamping tool to pass through, which is conducive to further avoiding contamination of the component carrier by manual operation.

[0013] According to another exemplary implementation method of the utility model, an arc-shaped opening is provided along both long sides of the rectangular opening, and the arc-shaped opening is used for the passage of the clamp. The arc-shaped opening is provided on the long side of the rectangular opening, which is conducive to adjusting the size of the arc-shaped opening according to actual needs, for example, the length of the connecting portion between the arc-shaped opening and the long side of the rectangular opening can be increased. In one embodiment, the arc-shaped opening is symmetrically provided on the corresponding two long sides of the opening, and the symmetrical arrangement can make it easier for the operator to put in / take out the component carrier from different directions, while enhancing the structural stability of the cleaning frame.

[0014] According to another exemplary implementation method of the utility model, an arc-shaped opening is provided along any two corresponding sides of the square opening, and the arc-shaped opening is used for the clamp to pass through. In one embodiment, the arc-shaped openings are symmetrically arranged on the two corresponding long sides of the opening, and this symmetrical arrangement can make it easier for the robot arm or the operator to put in / take out the component carrier from different directions, while enhancing the structural stability of the cleaning frame.

[0015] According to another exemplary implementation method of the present invention, the length of the rectangular opening is 15 mm-85 mm.

[0016] According to another exemplary implementation method of the present invention, the length of the rectangular opening is 20 mm-35 mm.

[0017] According to another exemplary implementation method of the present invention, the width of the rectangular opening is 15 mm-65 mm.

[0018] According to another exemplary implementation method of the present invention, the width of the rectangular opening is 20 mm-25 mm.

[0019] The above-mentioned size range can be adjusted according to actual needs, that is, adjusted according to the size of the component carrier that needs to be cleaned.

[0020] According to another exemplary implementation method of the present invention, the length of each side of the square opening is 15 mm-25 mm.

[0021] According to another exemplary implementation method of the present invention, the length of each side of the square opening is 20 mm.

[0022] According to another exemplary implementation method of the utility model, the distance from the arc-shaped opening to one side of the component carrier is 6mm-10mm, and the width of the arc-shaped opening is 10mm-14mm. In one embodiment, the width of the arc-shaped opening may refer to the length of the arc-shaped opening at the connection of the corresponding opening connected thereto. The size range of the arc-shaped opening may be adjusted according to actual needs, that is, adjusted according to the size of the component carrier to be cleaned, or adjusted according to the size of the robot arm or the thickness of the operator's fingers, the frequency of the operator's insertion / removal of the component carrier, etc.

[0023] According to another exemplary implementation method of the utility model, a plurality of support points are arranged along the periphery of the opening, which are configured to support the component carrier. In one embodiment, the intervals between the plurality of support points are the same, which can evenly distribute the pressure generated on the surface of the component carrier (especially on the frame area) when supporting the component carrier, thereby reducing the quality problems such as breakage and damage of the component carrier due to uneven force. In addition, the support points have a certain thickness (0.5mm-0.8mm), so that when the component carrier is fixed in the cleaning frame, its (lower) surface is at a certain distance from the supporting structure of the cleaning line (such as rollers, conveyor belts, etc.), thereby further reducing collisions, scratches and other unexpected damage.

[0024] According to another exemplary implementation method of the utility model, the same number of multiple support points are arranged on two opposite sides of the opening, and the positions of the multiple support points on the two opposite sides correspond one to one along the plane of the opening. The one-to-one correspondence of the positions of the support points along the plane of the opening can be understood as the support points being arranged in a mirror image / symmetrical manner on the two opposite sides of the opening, and the symmetrical structure further enables the pressure generated on the surface of the component carrier (especially the frame area) when supporting the component carrier to be evenly distributed, thereby reducing the quality problems of the component carrier such as breakage and damage due to uneven force. In addition, the structural stability of the cleaning frame can also be ensured.

[0025] According to another exemplary implementation method of the utility model, the minimum support area of ​​each of the multiple support points is 1.57 mm2. This minimum support area can ensure that sufficient support force is provided to the component carrier while reducing the contact area between the support point and the surface of the component carrier (especially the frame area), so that component carriers with smaller sizes and denser circuits can be cleaned (such as when the circuit area is very close to the edge of the component carrier and the frame area is very small).

[0026] According to another exemplary implementation method of the utility model, a plurality of support points are arranged along two opposite sides where no arc-shaped opening is arranged, and the support points are configured as support component carriers. This arrangement further ensures sufficient support force.

[0027] According to another exemplary implementation method of the utility model, the same number of multiple support points are arranged on two opposite sides, and the positions of the multiple support points on the two opposite sides correspond one to one along the plane of the opening. "The positions of the support points correspond one to one along the plane of the opening" can be understood as the support points being arranged in a mirrored / symmetrical manner on the two opposite sides of the opening, and the symmetrical structure further enables the pressure generated on the surface of the component carrier (especially the frame area) when supporting the component carrier to be evenly distributed, thereby reducing the quality problems of the component carrier such as breakage and damage due to uneven force. In addition, the structural stability of the cleaning frame can also be guaranteed.

[0028] According to another exemplary implementation method of the utility model, multiple support points are arranged along the four sides of the opening, and the same number of multiple support points are arranged on two opposite sides, which are configured to support the component carrier, and the positions of the multiple support points on the two opposite sides correspond one to one along the plane of the opening. "The positions of the support points correspond one to one along the plane of the opening" can be understood as the support points on the four sides of the opening, and the support points on each side are mirrored / symmetrically arranged with the support points on the symmetrical sides. This central symmetrical structure further makes it possible to evenly distribute the pressure on the surface of the component carrier (especially the frame area) when supporting the component carrier, thereby reducing the quality problems of the component carrier such as breakage and damage due to uneven force. In addition, the structural stability of the cleaning frame can also be guaranteed.

[0029] According to another exemplary implementation method of the utility model, the number of multiple support points on both sides of the opening with the arc-shaped opening is less than the number of multiple support points on both sides of the opening without the arc-shaped opening. In another embodiment, the number of multiple support points on both sides of the opening with the arc-shaped opening is greater than or equal to the number of multiple support points on both sides of the opening without the arc-shaped opening, and the number of support points can be adjusted by adjusting the density of the support points on the same side.

[0030] According to another exemplary implementation method of the utility model, the distance from at least one slot to any one of the at least two openings is less than the width of at least one slot. In an embodiment, the width of the slot is greater than the distance from the slot to the edge of the adjacent opening, that is, the connection between the slot and the opening is very narrow. This compact design ensures the structural stability of the cleaning frame while allowing as many openings as possible to be provided in the cleaning frame, thereby improving the cleaning efficiency.

[0031] According to another exemplary implementation method of the utility model, the material of the cleaning frame is at least one of the following materials: resin, cyanate resin, polyphenylene derivative, prepreg material, polyimide, polyamide, liquid crystal polymer, epoxy resin-based laminated film, polytetrafluoroethylene. The cleaning frame made of the above materials can ensure the structural stability of the cleaning frame, and they are also commonly used insulating materials in the production of component carriers, so the cost of purchasing additional specific materials can be reduced.

[0032] According to another exemplary implementation method of the utility model, the cleaning frame is used for high-pressure cleaning of component carriers with a length of 20mm-35mm and a width of 20mm-25mm, the number of component carriers to be cleaned is greater than or equal to 30, and the high-pressure pressure value range is 0.5kg / cm 2 Up to 10kg / cm 2 .

[0033] The cleaning frame in the cleaning device for component carriers disclosed in the utility model can be suitable for small-sized component carriers with a length of less than 100 mm and a width of less than 50 mm, so as to keep them from displacement during the cleaning process and reduce the generation of scratches. In addition, the structure of the cleaning frame can realize the removal of the water flow impact force during the flushing process, better protect the component carriers, and ensure the yield of the product. Through the cleaning frame, multiple component carriers with smaller sizes can be fixed in the opening of the cleaning frame, so that they do not change their positions during the cleaning process, and thus no unexpected collisions and frictions will occur, which can greatly improve the yield of the product. At the same time, the trough body arranged between the two openings can flow the cleaning medium, that is, during the high-pressure flushing process, the high-pressure water flow can flow from one surface of the cleaning frame to another relative surface through the trough body. In addition, the length of the trough body is greater than the length of the opening, which can further improve the efficiency of the flow of the cleaning medium, thereby reducing the pressure of the high-pressure water flow on the entire cleaning frame and the surface of the component carrier placed therein, which can effectively prevent the possibility of the component carrier being broken or damaged during the high-pressure flushing process.

[0034] In the context of the present invention, the term "component carrier" can particularly refer to any supporting structure capable of accommodating one or more components thereon and / or therein for providing mechanical support and / or electrical connectivity. In other words, the component carrier can be configured as a mechanical and / or electronic carrier for components. In particular, the component carrier can be one of a printed circuit board (PCB), an organic interposer, a substrate-like PCB (SLP) and an IC (integrated circuit) substrate. The component carrier can also be a hybrid board combining different component carriers in the component carriers of the types mentioned above. In the context of the present application, the component carrier can include a layer stack (including, for example, at least one electrically insulating layer structure and at least one conductive layer structure) and an electronic component embedded in a cavity of the layer stack. In another embodiment, the component carrier can include a base structure connected to the electronic component embedded in the cavity of the base structure.

The fibers are usually in a woven form, and the matrix can be used to join them together and / or join them to other components during the manufacturing process. Prepreg can be a printed circuit board material in an uncured state, such as FR4 or FR5. For example, glass fibers can be embedded in an epoxy resin matrix, however, the material is still uncured or at least not fully cured, making the material deformable to a certain extent. At least partially deformable, physical structures can be pressed into and / or penetrated into the material. For example, a conductive column structure or an electronic component of a base structure can be at least partially pressed into a prepreg material. The prepreg can be put into a cured state by applying high temperature and / or high pressure. The cured material may no longer be deformed.

[0052] Figure 1 A cleaning frame 100 in a cleaning device for a component carrier 101 is shown, comprising: a plurality of openings 102, each opening 102 being configured to fix a component carrier 101; wherein at least one trough 103 is provided between at least two openings 102, and is configured for flowing a cleaning medium; and a length of at least one trough 103 extending along the plane of the cleaning frame 100 is greater than a length of each of the at least two openings 102.

[0053] In one embodiment, a plurality of component carriers 101 with smaller dimensions can be fixed in the openings 102 of the cleaning frame 100 through the cleaning frame 100. The dimensions of each component carrier 101 are, for example, less than 100 mm in length and less than 50 mm in width. The dimensions of each opening 102 are slightly larger than the dimensions of each component carrier 101 to ensure that the component carrier 101 can be placed. Since the dimensions of each opening 102 do not exceed the dimensions of each component carrier 101 by too much, the component carrier 101 can be ensured to remain stable when subjected to high-pressure washing. At least one groove 103 is provided between every two openings 102 in the longitudinal direction, and the groove 103 extends along the plane of the cleaning frame 100, that is, the length in the longitudinal direction is greater than the length of each opening 102. The advantage of such an arrangement is that when the cleaning frame 100 carries a plurality of component carriers 101 and performs high-pressure cleaning, the direction in which the cleaning medium flows is perpendicular to the surface of the component carrier 101 fixed in the cleaning frame 100, and along with the rolling direction of the roller in the cleaning device, the cleaning medium is flushed from left to right or from right to left, thereby ensuring that the tank body 103 has sufficient length for the cleaning medium to pass through, thereby reducing the impact force of the cleaning medium under high pressure on the cleaning frame 100 and the component carrier 101. The tank body 103 can also extend along the lateral direction of the cleaning frame 100, as long as the length of the tank body 103 is greater than the length of each opening 102. At this time, it is only necessary to adjust the direction of high-pressure flushing, that is, when the cleaning frame 100 carries multiple component carriers 101 and performs high-pressure cleaning, the cleaning medium is flushed from the bottom to the top or from the top to the bottom (i.e., perpendicular to the paper surface), which can ensure that the tank body 103 has enough length to allow the cleaning medium to pass through, reduce the impact force of the cleaning medium under high pressure on the cleaning frame 100 and the component carrier 101, and effectively prevent the component carrier 101 from being broken or damaged during the high-pressure flushing process. At the same time, as shown in the figure, no matter which direction the tank body 103 is set, there must be an unopened area between two adjacent tank bodies 103, that is, the two tank bodies 103 are not connected, so as to ensure the structural stability of the cleaning frame 100. At the same time, the component carrier 101 of a smaller size is fixed in the opening 102 of the cleaning frame 100 so that its position does not change during the cleaning process, thereby preventing unexpected collisions and frictions, which can greatly improve the yield of the product.

[0054] In another embodiment, the plurality of openings 102 are arranged in an array, and the lateral distance between the centers of at least two openings 102 is different from the longitudinal distance between the centers of the two openings 102. The openings 102 arranged in an array form can fix the component carrier 101 in the cleaning frame 100 in a neat form, which is not only easy to carry out production management, but also can ensure that the flushing pressure generated during the cleaning process is evenly distributed, thereby further reducing the possibility of the component carrier 101 being broken or damaged during the high-pressure flushing process. Specifically, the plurality of openings 102 are arranged in a rectangular layout. The advantage of the rectangular layout is that the design is convenient and simple, and it is stable enough to facilitate the placement and removal of multiple component carriers 101, and it is visually beautiful and orderly. The lateral distance between the centers of the two openings 102 is different from the longitudinal distance between the centers of the two openings 102. For example, Figure 1 As shown, when the tank body 103 is arranged between two openings 102 adjacent in the transverse direction along the longitudinal direction of the cleaning frame 100, the distance between the centers of the two openings 102 adjacent in the transverse direction is smaller than the distance between the centers of the two openings 102 adjacent in the longitudinal direction. When the tank body 103 is arranged between two openings 102 adjacent in the longitudinal direction along the transverse direction of the cleaning frame 100, the distance between the centers of the two openings 102 adjacent in the longitudinal direction is smaller than the distance between the centers of the two openings 102 adjacent in the transverse direction. In another possible embodiment, the transverse distance between the centers of at least two openings 102 may also be the same as the longitudinal distance between the centers of the two openings 102, which can ensure that the openings 102 are arranged more compactly in the cleaning frame 100, thereby improving the cleaning efficiency.

[0055] In another embodiment, at least one slot 103 extends between the two openings 102 and corresponds to the same plane of the openings 102, and extends from one end of the cleaning frame 100 to the other end of the cleaning frame. Figure 1As shown, a slot body 103 is arranged along the longitudinal direction of the cleaning frame 100, and is arranged in the same plane as the opening 102 of the cleaning frame 100. There is no restriction on the length of the slot body 103, that is, it can extend from one end of the cleaning frame 100 to the other end of the cleaning frame 100 along the longitudinal direction, as long as an unopened area is left between two adjacent slot bodies 103 in the longitudinal direction to ensure the structural stability of the entire cleaning frame 100. As mentioned above, the slot body 103 can also be arranged along the transverse direction of the cleaning frame 100, and is arranged in the same plane as the opening 102 of the cleaning frame 100. There is no restriction on the length of the slot body 103, that is, it can extend from one end of the cleaning frame 100 to the other end of the cleaning frame 100 along the transverse direction, as long as an unopened area is left between two adjacent slot bodies 103 in the transverse direction to ensure the structural stability of the entire cleaning frame 100. However, in another embodiment (not shown in the figure), two adjacent tank bodies 103 may also be connected to form a longer tank body, but its length cannot be greater than the distance from one end to the other end of the cleaning frame 100, so as to ensure the structural stability of the cleaning frame 100. In this embodiment, because the length of the tank body 103 is longer and its length is less than the extension distance from one end to the other end of the cleaning frame 100, the advantage of such a setting is that while ensuring the structural stability of the cleaning frame 100, the efficiency of the flow of the cleaning medium can be further improved.

[0056] In another embodiment, the width of at least one of the grooves 103 is smaller than the lateral distance between the two openings 102, or the width of at least one of the grooves 103 is smaller than the longitudinal distance between the two openings 102. Specifically, the width of the groove 103 should not be set too wide, considering the overall strength of the cleaning frame 100, and also considering that the impact force of the high-pressure flushing should not be dispersed too much, so as to avoid insufficient impact force to flush away impurities on the component carrier 101. When the groove 103 is arranged along the longitudinal direction of the cleaning frame 100, the width of the groove 103 is smaller than the distance between two adjacent openings 102 in the lateral direction. When the groove 103 is arranged along the lateral direction of the cleaning frame 100, the width of the groove 103 is smaller than the distance between two adjacent openings 102 in the longitudinal direction.

[0057] In another embodiment, the opening 102 is a rectangular opening.

[0058] In another embodiment, the opening 102 is a square opening.

[0059] Specifically, the opening 102 may be a rectangular opening or a square opening, and is made accordingly according to the shape of the component carrier 101. The rectangular opening or the square opening can also effectively maintain an array arrangement, so that the openings 102 of the cleaning frame 100 are neat and beautiful. The shape of the opening 102 can be adjusted according to the size of the component carrier to be cleaned, and a suitable opening shape can further ensure the cleaning efficiency and the stability of the overall structure.

[0060] Figure 2 Taking the opening 102 as a rectangular opening as an example, it is shown that an arc-shaped opening 104 is respectively provided along the corresponding two sides of the rectangular opening, and the arc-shaped opening 104 is configured to / suitable for the passage of a clamping member. In particular, an arc-shaped opening 104 is provided along the corresponding two sides of the rectangular opening, and the arc-shaped opening is configured to / suitable for the passage of a clamping member. The clamping member can be a robot arm or an operator's finger.

[0061] Taking the operator's finger as an example, whether before or after cleaning (especially after cleaning is completed), the operator needs to put in / take out the component carrier 101, and the arc-shaped opening 104 is suitable for the finger to pass through, so that the operator only needs to touch the frame area of ​​the component carrier 101 with the finger when taking out the component carrier 101, without directly touching the line area of ​​the component carrier 101 where the circuit, pad, etc. are set, which can reduce the contamination of the surface of the component carrier 101 by foreign matter (such as oil stains, etc.) on the finger, thereby further improving the product yield. In addition, during the cleaning process, the arc-shaped opening 104 can also be used to flow the cleaning medium to reduce the flushing pressure on the cleaning frame and the surface of the component carrier 101. When the clamping member is a robotic arm, the arc-shaped opening 104 is also suitable for the passage of the robotic arm, so that when the robotic arm takes out the component carrier 101, it only needs to use the robotic arm's claws or similar mechanical structures to clamp the frame area of ​​the component carrier 101 without directly contacting the line area where the circuit, pad, etc. are set in the component carrier 101. This can reduce the contamination of the surface of the component carrier 101 by dust attached to the robotic arm, thereby further improving the product yield.

[0062] In one embodiment, in order to further avoid damage to the surface of the component carrier 101, when taking and placing the component carrier 101 on the cleaning frame 100, the operator should avoid contact with the surface of the component carrier 101 as much as possible. If the component carrier 101 needs to be taken and placed manually, in order to avoid large-area contact with the surface of the component carrier 101 (especially the circuit surface provided with circuits, pads, etc.), a circular arc opening 104 is provided on each of the corresponding sides of the rectangular opening, and two fingers are used to pass through at the same time. The two fingers are clamped on the two sides of the body of the component carrier 101 for taking and placing, which can completely avoid contact with the surface of the component carrier 101, thereby further reducing damage to the surface of the component carrier 101. When the clamping member is a robotic arm, the working principle is the same and will not be described in detail here.

[0063] In another embodiment, when the opening 102 is a rectangular opening, Figure 2 As shown, an arc-shaped opening 104 is provided along each of the two long sides of the rectangular opening. Because the trough 103 is provided between two adjacent rectangular openings in the transverse direction along the longitudinal direction of the cleaning frame 100, and the distance between the centers of the two adjacent rectangular openings in the transverse direction is smaller than the distance between the centers of the two adjacent rectangular openings in the longitudinal direction, in order to facilitate the manufacturing process, the two arc-shaped openings 104 are provided at the two long sides of the rectangular opening, and two fingers simultaneously pass through the two arc-shaped openings 104 provided at the long sides of the rectangular opening, and are clamped on both sides of the component carrier 101 for picking and placing. When the tank 103 is arranged between two adjacent rectangular openings in the longitudinal direction along the transverse direction of the cleaning frame 100, the distance between the centers of the two adjacent rectangular openings in the longitudinal direction is smaller than the distance between the centers of the two adjacent rectangular openings in the transverse direction. At this time, in order to facilitate the manufacturing process, two arc-shaped openings 104 can be arranged along the two short sides of the rectangular opening. Two fingers pass through the two arc-shaped openings 104 arranged on the short sides of the rectangular opening at the same time, and clamp the two sides of the component carrier 101 body for picking and placing, which can also completely avoid contacting the surface of the component carrier 101, thereby further reducing damage to the surface of the component carrier 101. When the clamping member is a mechanical arm, the working principle is the same, and it will not be repeated here.

[0064] In another embodiment, when the opening 102 is a square opening, an arc-shaped opening 104 is provided along any two corresponding sides of the square opening, and the arc-shaped opening 104 is used for fingers to pass through. When the tank body 103 is provided between two adjacent square openings in the transverse direction along the longitudinal direction of the cleaning frame 100, and the distance between the centers of the two adjacent square openings in the transverse direction is smaller than the distance between the centers of the two adjacent square openings in the longitudinal direction, in order to facilitate the manufacturing process, the two arc-shaped openings 104 are provided at two sides of the square opening that are different from the directions in which the tank body 103 is provided, and two fingers pass through the two arc-shaped openings 104 provided at the above two sides of the square opening at the same time, and are clamped on both sides of the component carrier 101 for picking and placing. When the tank body 103 is arranged between two adjacent square openings in the longitudinal direction along the transverse direction of the cleaning frame 100, the distance between the centers of the two adjacent square openings in the longitudinal direction is smaller than the distance between the centers of the two adjacent square openings in the transverse direction. At this time, in order to facilitate the manufacturing process, the two arc-shaped openings 104 are arranged on two sides of the square opening that are different from the direction in which the tank body 103 is arranged. Two fingers pass through the two arc-shaped openings 104 arranged on the above two sides of the square opening at the same time, and clamp the two side edges of the component carrier 101 body for picking and placing, which can also completely avoid contacting the surface of the component carrier 101, thereby further reducing damage to the surface of the component carrier 101. When the clamping member is a mechanical arm, the working principle is the same and will not be repeated here.

[0065] In the above embodiment, when the opening 102 is a rectangular opening, the length of the rectangular opening is 15 mm-85 mm, especially 20 mm-35 mm, and the width of the rectangular opening is 15 mm-65 mm, especially 20 mm-25 mm. The above size range can be adjusted according to actual needs, that is, adjusted according to the size of the component carrier to be cleaned.

[0066] In the above embodiment, when the opening 102 is a square opening, the length of each side of the square opening is 15 mm-25 mm, in particular, 20 mm. The above size range can be adjusted according to actual needs, that is, adjusted according to the size of the component carrier to be cleaned.

[0067] In the above embodiment, the distance that the arc-shaped opening 104 extends from one side of the component carrier 101 is 6 mm-10 mm, and the width of the arc-shaped opening 104 is 10 mm-14 mm. The width of the arc-shaped opening may refer to the length of the arc-shaped opening at the connection point of the corresponding opening connected thereto, such as Figure 2As shown, the width W of the arc-shaped opening 104 is 12 mm by way of example. The size range of the arc-shaped opening 104 can be adjusted according to actual needs, that is, according to the size of the component carrier 101 to be cleaned, or according to the size specifications of the robot arm, or the thickness of the operator's fingers, the frequency of the operator's insertion / removal of the component carrier, etc.

[0068] like Figure 3 As shown, a plurality of supporting points 105 are arranged along the periphery of the opening 102 , which are configured to support the component carrier 101 .

[0069] In one embodiment, in order to further save the material usage of the cleaning frame and reduce the cost, the bottom of the opening 102 is hollowed out. In order to prevent the component carrier 101 from being displaced when subjected to high-pressure washing, a plurality of support points 105 are arranged along the periphery of the opening 102. The arrangement method is not limited. For example, the support points 105 can be arranged by welding, clamping or gluing. The plurality of support points 105 are used to support the component carrier 101. In a preferred embodiment, the spacing distances between the plurality of support points 105 are equal. This can make the pressure generated on the surface of the component carrier 101 (especially on the frame area) when supporting the component carrier 101 be evenly distributed, thereby reducing the quality problems such as breakage and damage of the component carrier 101 due to uneven force. In addition, the support point 105 has a certain thickness, so that when the component carrier 101 is fixed in the cleaning frame 100, its (lower) surface is at a certain distance from the support structure (such as rollers, conveyor belts, etc.) of the cleaning line, thereby further reducing the collision, scratches and other undesirable damage.

[0070] In another embodiment, the same number of supporting points 105 are disposed on two opposite sides of the opening 102, and the positions of the supporting points 105 on the two opposite sides correspond one to one along the plane of the opening 102. Figure 3 As shown, in order to keep the component carrier 101 from being displaced on the opening 102 when subjected to high-pressure washing, four support points 105 are provided on each of the two opposite sides of the opening 102, that is, the positions of the support points 105 correspond one to one in the transverse direction, and the longitudinal distances of the support points 105 on each side are equal in the longitudinal direction. It is worth noting that the settings of "2" and "4" support points 105 mentioned in the embodiments are only illustrative embodiments, and the utility model does not specifically limit the number of support points 105, as long as the number of support points 105 on the opposite sides is the same and corresponds one to one.

[0071] In the above embodiment, the minimum support area of ​​each of the plurality of support points 105 is 1.57 mm2. This minimum support area can ensure that sufficient support force is provided to the component carrier 101 while reducing the contact area between the support point 105 and the surface of the component carrier 101 (especially the frame area), so that the component carrier 101 with a smaller size and denser circuits can be cleaned (such as when the circuit area is very close to the edge of the component carrier and the frame area is very small).

[0072] In one embodiment, a plurality of support points 105 are provided along two opposite sides of the opening 102 where the arc-shaped opening 104 is not provided, and are configured to support the component carrier 101. Figure 3 As shown, the opening 102 is a rectangular opening, and each of its two opposite long sides is provided with an arc-shaped opening 104 , and each of the two opposite short sides without the arc-shaped opening 104 is provided with four supporting points 105 for supporting the component carrier 101 .

[0073] In another embodiment, a plurality of support points 105 are provided along two opposite sides of the opening 102 where the arc-shaped opening 104 is provided, which are configured to support the component carrier 101. Figure 4 As shown, the opening 102 is a rectangular opening. Since an arc-shaped opening 104 is provided on each of the two relatively long sides, the positions left for setting the support points 105 become less, and two support points 105 are provided on each of the two long sides of the opening 102. The positions of the multiple support points 105 on the two relatively sides correspond one to one along the plane extension of the opening 102, that is, the positions of the support points 105 correspond one to one in the longitudinal direction, and the support points 105 on each side are at the same lateral distance from the center point of the arc-shaped opening 104.

[0074] In another embodiment, multiple support points 105 are arranged along the four sides of the opening 102, and the same number of support points 105 are arranged on two opposite sides, which are configured to support the component carrier 101, and the positions of the multiple support points 105 on the two opposite sides correspond one to one along the plane of the opening. Figure 5As shown, the opening 102 is a rectangular opening. Since an arc-shaped opening 104 is provided on each of the two relatively long sides, the positions left for setting the support points 105 become less. Two support points 105 are provided on each of the two relatively long sides of the opening 102. The positions of the multiple support points 105 on the relatively two sides correspond one to one along the plane of the opening 102, that is, the positions of the support points 105 correspond one to one in the longitudinal direction, and the positions of the support points 105 on each side are equal in the lateral distance from the center point of the arc-shaped opening 104. Four support points 105 are provided on each of the relatively two short sides where no arc-shaped opening 104 is provided. The positions of the support points 105 correspond one to one in the lateral direction, and the longitudinal distances of the support points 105 on each side are equal in the longitudinal direction. Figure 5 As shown, the number of the plurality of supporting points 105 on the two sides provided with the arc-shaped opening 104 is less than the number of the plurality of supporting points 105 on the two sides not provided with the arc-shaped opening 104 .

[0075] In the above embodiment, the minimum supporting area of ​​each supporting point 105 among the plurality of supporting points 105 is still 1.57 mm 2 .

[0076] When the opening 102 is a square opening, the arrangement of the support points 105 is the same as when the opening is a rectangular opening, and will not be described in detail herein.

[0077] In one embodiment, the distance from at least one slot 103 to any one of the at least two openings 102 is smaller than the width of at least one slot 103. Figure 5 As shown, the distance A from the tank body 103 to the adjacent (left) opening 102 is smaller than the width B of the tank body 103 itself. In this embodiment, the width B of the tank body 103 is larger than the distance A from the edge of the adjacent opening 102, that is, the connection between the tank body 103 and the opening 102 is very narrow. This compact design can ensure the structural stability of the cleaning frame 100 while allowing as many openings 102 as possible to be provided in the cleaning frame 100, thereby improving the cleaning efficiency.

[0078] In one embodiment, the cleaning frame 100 is made of at least one of the following materials: resin, cyanate resin, polyphenylene derivative, prepreg material, polyimide, polyamide, liquid crystal polymer, epoxy resin-based laminated film, polytetrafluoroethylene. The cleaning frame 100 made of the above materials can ensure the structural stability of the cleaning frame 100, and they are also commonly used insulating materials in the production of component carriers 101, so the cost of purchasing additional specific materials can be reduced.

[0079] In one embodiment, the cleaning frame 100 is used for high-pressure cleaning of component carriers 101 with a length of 20 mm to 35 mm and a width of 20 mm to 25 mm, and the number of cleaning component carriers 101 is greater than or equal to 30. The size of the cleaning frame and the number of cleaning component carriers 101 can be adjusted according to actual production needs, and are not limited to the size and number specified in this embodiment.

[0080] A cleaning frame in a cleaning device for component carriers disclosed in the utility model can be suitable for small-sized component carriers with a length of less than 100 mm and a width of less than 50 mm, so as to prevent displacement during the cleaning process and reduce the generation of scratches. In addition, the structure of the cleaning frame can remove part of the impact force of the water flow during the flushing process, thereby better protecting the component carriers and ensuring the yield of the product.

[0081] The above are only various embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
