Description
[Technical field]
[0001] The present application relates to the field of electronic device technology, and in particular to connectors and electronic devices. [Background technology]
[0002] In electronic devices, electrical elements (such as chips and main boards) can be connected using connectors to perform functions such as electrical signal transmission between the electrical elements. For example, a computer usually includes various electrical elements such as a main board and chips. The chips can be mounted on the main board using connectors, and electrical connections between the chips and the main board are performed. However, current connectors have shortcomings in their structural design. As a result, electrical signals are significantly attenuated when passing through the connectors, which does not help improve signal transmission performance. Summary of the Invention [Means for solving the problem]
[0003] The present application provides connectors and electronic devices that help improve signal transmission performance.
[0004] According to one aspect, the present application provides a method for producing a method for a method of manufacturing a semiconductor device comprising: A connector is provided. The connector comprises: The substrate and M conductive terminals are included. nothing. substrate To is M through holes is established. The M conductive terminals are arranged to pass through the M through holes in one-to-one correspondence, and the conductive terminals include a first conductive portion, a second conductive portion, and a holding portion. The first conductive portion is located at one end of the conductive terminal, the second conductive portion is located at the other end of the conductive terminal, and the holding portion is located between the first conductive portion and the second conductive portion. The holding portion is fixed by using a fixing medium. Through hole M is an integer equal to or greater than 1. Specifically, the M conductive terminals are arranged in one-to-one correspondence with the M through holes. One conductive terminal is arranged to pass through each through hole, and each conductive terminal is fixed to the substrate using a fixing medium located in the through hole. FixedAccording to the connector provided in the present application, in order to facilitate improving the signal transmission performance of the conductive terminal, the conductive terminal may be fixed to the substrate using a fixing medium such that the arrangement of a stub structure may be avoided.
[0005] In specific implementation, the structure types of the first conductive portion and the second conductive portion may be various.
[0006] For example, the first conductive portion may be a resilient arm structure or a solder ball structure. The second conductive portion may be a resilient arm structure or a solder ball structure. The structure types of the first conductive portion and the second conductive portion may be the same or different.
[0007] In another example, the conductive terminal is ,or , may include a first segment and a second segment separated from each other. For example, the first conductive portion and a portion of the holding portion may be located in the first segment, and the second conductive portion and another portion of the holding portion may be located in the second segment. In other words, by arranging the separation structure, the convenience of mounting the conductive terminal can be improved. For example, when the conductive terminal penetrates the through hole, interference may occur between the first conductive portion or the second conductive portion and the through hole, which may reduce the convenience of assembling the conductive terminal and the board. Therefore, after the conductive terminal is separated into the first segment and the second segment, the first conductive portion and the second conductive portion can be prevented from penetrating the through hole. In this way, , No. A first conductive portion and a second conductive portion Through holes and Therefore, interference between the two can be avoided.
[0008] In addition, the connector may further include a support base to maintain the relative positions of the conductive terminals and the substrate during the assembly process of the connector. FixedA support portion configured to be held by the support base may be disposed on the conductive terminal. The support base may be first fixed to the support portion of the conductive terminal before the conductive terminal is attached to the substrate. Then, the conductive terminal with the support base may be disposed on the upper plate surface of the substrate such that the support base abuts against one plate surface (e.g., the upper plate surface) of the substrate and the holding portion extends into the through hole. In other words, the conductive terminal may be stably disposed on the substrate by using the support base, therefore, The precise relative positions of the conductive terminals and the substrate are maintained.
[0009] In addition, when the connector is placed between the chip and the main board, under the action of the pushing force, the first conductive part or the second conductive part may be broken or have another defective state due to excessive deformation. The first conductive part is used as an example. After the support base is placed, one side of the support base may abut against the plate surface of the substrate, and the other side of the support base may abut against the bottom surface of the chip, thereby causing the first conductive part to be broken. fart past Excess pressure To avoid this, the minimum distance between the chip and the substrate can be limited.
[0010] Alternatively, the protrusion ,or, The protrusion may be disposed on the support base. The protrusion may effectively increase the height of the support base without significantly increasing the weight of the support base, which may be achieved by providing a first conductive portion. fart past Excess pressure Helps to avoid
[0011] In order to increase the minimum distance between the chip and the substrate during a specific arrangement, the protrusion may extend in a direction away from the substrate so that the top of the protrusion can abut the chip. without significantly increasing the weight of the support base The height of the support base can be increased ,child This helps to implement a lightweight design for the connector.
[0012] In addition, a conductive layer may be further disposed in the through-hole to realize an electrical connection between some of the conductive terminals. In addition, a conductive circuit may be further disposed on the substrate, and the conductive circuit may be electrically connected to the conductive layers that need to be electrically connected. Specifically, the conductive terminals may be electrically connected to the conductive layers in the corresponding through-holes using a fixing medium, and the conductive layers in different through-holes may be connected using a conductive circuit, thereby realizing an electrical connection between a plurality of conductive terminals.
[0013] The fixing medium may be a conductive material such as tin or silver that facilitates making an efficient electrical connection between the conductive terminals and the conductive layer.
[0014] The conductive circuit may be disposed on one surface of the substrate, or on both surfaces of the substrate.
[0015] Alternatively, the substrate may be Multiple When the conductive circuit is disposed, the conductive circuit is ,or , may be disposed between two adjacent (or stacked) sub-substrates.
[0016] According to another aspect, the present application provides a method for producing a method for manufacturing a semiconductor device comprising: There is further provided an electronic device comprising: The device includes a first electrical element, a second electrical element, and a connector. nothing. The first electrical element includes a pad, and the second electrical element also includes a pad on top. The pad of the first electrical element may be connected to a first conductive portion of the conductive terminal. The pad of the second electrical element may be connected to a second conductive portion of the conductive terminal. In other words, the conductive terminal can implement an electrical connection between the first electrical element and the second electrical element.
[0017] In practical applications, the first electrical component may be an electrical component such as a chip, and the second electrical component may be an electrical component such as a main board. The types of the first electrical component and the second electrical component are not limited in this application. In addition, the electronic device may be of the type of a mobile phone, a tablet computer, a desktop computer, or a television. In other words, the connector is To effect an electrical connection between the electrical elements that need to be connected, It may be applied to several different types of electronic devices. stomach .

[0019] In order to make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the present application in detail with reference to the accompanying drawings.
[0020] In order to facilitate understanding of the connector provided in the embodiments of the present application, the following will first describe an application scenario of the connector.
[0021] 1, in the embodiment provided in the present application, the chip 20 may be connected to the main board 30 using a connector 10 (which may also be understood as a chip socket). The connector 10 may implement a signal connection between the chip 20 and the main board 30, and a power supply circuit on the main board 30 may also use the connector 10 to supply power to the chip 20.
[0022] As shown in FIG. 1, the connector 10 may include a housing 101 and a conductive terminal 12 (two conductive terminals are shown in the figure). The conductive terminal 12 may be made of a material having good electrical conductivity, such as copper, aluminum, silver, or an alloy of copper, aluminum, and silver. The housing 101 may be made of a material having good insulating properties, such as plastic, nylon, or liquid crystal polymer. The conductive terminal 12 is fixed to the housing 101 and configured to maintain the position of the conductive terminal 12 to facilitate implementing a good connection between the chip 20 and the main board 30. From a functional point of view, the conductive terminal 12 typically includes four parts: a first conductive portion 121, a second conductive portion 122, a holding portion 123, and a stub structure (stub) 124. The first conductive portion 121 is configured to be electrically connected to a pad 21 (or another conductive structure) of the chip 20, and the second conductive portion 122 is configured to be electrically connected to a pad 31 (or another conductive structure) on the main board 30. The retaining portion 123 and the stub structure 124 are configured to be fixed to the housing 101. Currently, the conductive terminal 12 is fixed to the housing 101 by physical interference between the retaining portion 123 and the stub structure 124.
[0023] 1, the stub structure 124 is a portion extending outward from one side surface of the holding portion 123. The conductive terminal 12 may be fixed to the housing 101 using the stub structure 124 and the holding portion 123. However, in practical applications, the stub structure 124 may significantly degrade the signal transmission performance of the conductive terminal 12. The signal transmission performance of the conductive terminal 12 includes at least parameters such as a resonant frequency and a bandwidth.
[0024] As shown in FIG. 2, FIG. 2 shows a diagram of a signal data simulation of a conductive terminal 12 having a stub structure 124 .
[0025] FIG. 3 shows a diagram of signal data simulation of the conductive terminal 12 without the stub structure 124.
[0026] 2 and 3, the abscissa is the resonant frequency in Ghz and the ordinate is the insertion loss.
[0027] 2 and 3, it can be seen that when the stub structure 124 exists, the conductive terminal 12 resonates near point A. The resonant frequency of point A is about 41 Ghz. When the stub structure 124 does not exist, the conductive terminal 12 resonates near point B. The resonant frequency of point B is about 46 Ghz. When the conductive terminal 12 includes the stub structure 124, the resonant frequency of the conductive terminal 12 can be significantly reduced, which is conductive It can be seen that this does not help to increase the bandwidth of the transmission signal at terminal 12.
[0028] Therefore, the embodiments of the present application provide a connector that can effectively avoid disposing a stub structure to improve signal transmission performance.
[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and specific embodiments.

[0031] References to "one embodiment" or the like described herein indicate that one or more embodiments of the application include a particular feature, structure, or characteristic described with reference to the embodiment. Thus, statements such as "in one embodiment," "in some embodiments," and "in other embodiments" appearing in different places in this specification do not necessarily refer to the same embodiment.

[0032] As shown in FIG. 4, in the embodiment provided in the present application, the connector 10 includes a substrate 11 and a conductive terminal 12. To The upper and lower surfaces of the substrate 11 in communication with Through hole 111 will be established. The conductive terminal 12 is disposed to pass through the through hole 111, and a portion of the conductive terminal 12 is fixed to the inner wall of the through hole 111 using a fixing medium (not shown in the figure). Specifically, the conductive terminal 12 includes a first conductive portion 121, a second conductive portion 122, and a holding portion 123. The first conductive portion 121 is located at one end (upper end in the figure) of the conductive terminal 12, the second conductive portion 122 is located at the other end (lower end in the figure) of the conductive terminal 12, and the holding portion 123 is located between the first conductive portion 121 and the second conductive portion 122. The first conductive portion 121 is configured to extend from the upper end of the through hole 111 (or the upper plate surface of the substrate 11) and to be connected to the pad 21 of the chip 20. The second conductive portion 122 is configured to extend from the lower end of the through hole 111 (or the lower plate surface of the substrate 11) and to be connected to the pad 31 of the main board 30. In other words, the chip 20 can be electrically connected to the main board 30 using the conductive terminals 12 to perform functions such as transmitting electrical signals. In order to facilitate improving the signal transmission performance of the conductive terminals 12, the holding portion 123 can be fixed to the inner wall of the through-hole 111 using a fixing medium so that the arrangement of a stub structure can be avoided.
[0033] In a specific arrangement, the structures of the first conductive portion 121 and the second conductive portion 122 may vary.
[0034] For example, as shown in FIG. 4 and FIG. 5, in the embodiment provided in the present application, the first conductive portion 121 is an elastic arm structure, and the second conductive portion 122 is a solder ball structure. Specifically, in practical applications, the conductive terminal 12 can be compressed and fixed between the chip 20 and the main board 30. The first conductive portion 121 can elastically abut against the pad 21 through the elastic deformation of the first conductive portion 121, so as to improve the connection effect between the first conductive portion 121 and the pad 21. In addition, under the action of the compressive force, the second conductive portion 122 can also well abut against the pad 31, so as to improve the connection effect between the second conductive portion 122 and the pad 31.
[0035] During manufacturing, processes such as cutting or bending may be used to form the elastic arm structure (first conductive portion 121) of the conductive terminal 12. 2 is The conductive terminal 12 may be made of a material having good electrical conductivity, such as copper, aluminum, silver, or an alloy of copper, aluminum, and silver. The material of the conductive terminal 12 is not limited in this application.
[0036] Regarding the second conductive portion 122 , in practical application, a solder ball may be mounted to the lower end of the conductive terminal 12 using a welding process to fix the solder ball to the lower end of the conductive terminal 12 .
[0037] When the connector 10 is assembled, the conductive terminals 12 are inserted into the upper side of the substrate 11. Ran The fixing medium 13 can then be inserted into the through hole 111. but Inner wall of through hole 111 To solid Fixed Processes such as reflow soldering or sintering can be used to By The solder is injected into the through-hole 111. Finally, to form the second conductive portion 122, a solder ball can be mounted on the lower end of the conductive terminal 12, and the solder ball is stably fixed to the lower end of the conductive terminal 12 by secondary reflow soldering.
[0038] In practical applications, the second conductive portion 122 may be electrically connected to the pad 31 by abutting or welding methods. Specifically, the solder ball may be directly abutted to the pad 31 to implement the electrical connection between the conductive terminal 12 and the pad 31. Alternatively, the solder ball may be directly abutted to the pad 31 by a process such as reflow soldering to improve the connection effect between the conductive terminal 12 and the pad 31. By The solder ball may be welded to the pad 31. In practical applications, the solder ball structure may be a conductive spherical structure such as a tin ball or a silver ball, or Other shaped structures are also possible. The material of the solder ball structures is not limited in this application.
[0039] In another embodiment, both the first conductive portion 121 and the second conductive portion 122 may be solder ball structures. Alternatively, the second conductive portion 122 may be a solder ball structure and the second conductive portion 122 may be a resilient arm structure. Alternatively, both the first conductive portion 121 and the second conductive portion 122 may be resilient arm structures.
[0040] For example, as shown in FIG. 6, in the embodiment provided in the present application, both the first conductive part 121 and the second conductive part 122 are elastic arm structures. In practical applications, the first conductive part 121 can elastically abut the pad 21 of the chip 20 so as to ensure the connection effect between the conductive terminal 12 and the pad 21. Correspondingly, the second conductive part 122 can also elastically abut the pad 31 of the main board 30 so as to ensure the connection effect between the conductive terminal 12 and the pad 31. The specific shape structure of the elastic arm structure is not limited in the present application. In addition, the structural shape of the first conductive part 121 may be the same as or different from the structural shape of the second conductive part 122. In practical applications, when the elastic arm structure abuts the pad structure of the chip 20 or the main board 30, it can produce elastic deformation, and the elastic arm structure abuts well against the pad structure.
[0041] In addition, to facilitate attaching the conductive terminal 12 to the substrate 11, in some embodiments, the conductive terminal 12 may further include two separate portions.
[0042] 7, in the embodiment provided in the present application, the conductive terminal 12 includes a first segment 120a (upper portion in the figure) and a second segment 120b (lower portion in the figure). The first conductive portion 121 and a portion 123a (upper portion) of the holding portion 123 are located in the first segment 120a. The second conductive portion 122 and another portion 123b (lower portion) of the holding portion 123 are located in the second segment 120b.
[0043] Please refer to FIG. 6 and FIG. 7 together. During assembly, the first segment 120a can be inserted into the through-hole 111 from the upper side of the substrate 11, and the portion 123a (upper portion) of the holding portion 123 is fixed to the through-hole 111 using the fixing medium 13. The second segment 120b can be inserted into the through-hole 111 from the lower side of the substrate 11. Ran The first segment 120a can be inserted into the through hole 111, and another portion 123b (lower portion) of the holding portion 123 is fixed to the through hole 111 using a fixing medium 13. During assembly, the first segment 120a may be assembled to the substrate 11 first, and then the second segment 120b is assembled to the substrate 11. Alternatively, the second segment 120b may be assembled to the substrate 11 first, and then the first segment 120a is assembled to the substrate 11. Alternatively, the first segment 120a and the second segment 120b may be assembled to the substrate 11 at the same time.
[0044] In addition, in the assembly process of the connector 10, the relative positions of the conductive terminals 12 and the substrate 11 are maintain To achieve this, the connector 10 may further include a support base.
[0045] 8 and 9, a support portion 125 configured to be fixed to the support base 14 may be disposed on the conductive terminal 12. The support base 14 may be first fixed to the support portion 125 of the conductive terminal 12 before the conductive terminal 12 is attached to the substrate 11. Then, the conductive terminal 12 with the support base 14 may be disposed on the upper plate surface of the substrate 11, with the holding portion 123 extending into the through hole 111. In other words, the conductive terminal 12 may be stably disposed on the substrate 11 by using the support base 14, and thus an accurate relative position between the conductive terminal 12 and the substrate 11 is maintained.
[0046] The support base 14 may be a structural member made of a material with good insulating properties, such as plastic, nylon, or liquid crystal polymer. During manufacture, the support base 14 may be manufactured by a method such as injection molding, and then secured to the conductive terminal 12 by a method such as gluing. Alternatively, the support base 14 may be molded directly onto the support of the conductive terminal 12 using a process such as in-mold injection molding, and the combination of the support base 14 and the conductive terminal 12 is performed. The method of molding the support base 14 and the method of connecting the support base 14 and the conductive terminal 12 are not limited in this application.
[0047] In addition, in practical applications, the shape of the support base 14 may also vary.
[0048] For example, as shown in FIG. 8, in the embodiment provided in the present application, the support base 14 has a U-shaped structure. Specifically, the support base 14 includes a first plate 141, a second plate 142, and a third plate 143. The first plate 141 and the third plate 143 are disposed opposite to each other. The second plate 142 is located between the first plate 141 and the third plate 143, and is configured to implement that the first plate 141 is fixed to the third plate 143. The first plate 141 of the support base 14 is connected to the conductive terminal 12. The support base 14 can stably support the conductive terminal 12 on the substrate 11 using the U-shaped structure to avoid shaking occurring between the conductive terminal 12 and the substrate 11. In addition, by using the U-shaped structure, the weight of the support base 14 can be effectively reduced, which facilitates implementing a lightweight design of the connector.
[0049] In addition, in practical application, the support base 14 can further play a supporting role to avoid fault conditions such as damage caused by excessive pressure on the conductive terminals 12 .
[0050] 9, when the connector 10 is disposed between the chip 20 and the main board 30, under the action of the pushing force, the first conductive part 121 (elastic arm structure) may be broken or cause another defective state due to excessive deformation. After the support base 14 is disposed, the lower surface of the support base 14 may abut against the upper plate surface of the substrate 11, and the upper surface of the support base 14 may abut against the lower surface of the chip 20, so that the minimum distance between the chip 20 and the substrate 11 can be limited to avoid the state of excessive pressure on the first conductive part 121.
[0051] In specific implementation, the height of the support base 14 can be appropriately set according to actual requirements.
[0052] 10 and 11, a protrusion 144 may alternatively be disposed on the upper surface of the support base 14. The protrusion 144 may effectively increase the height of the support base 14 without significantly increasing the weight of the support base 14, which helps to avoid excessive pressure on the first conductive portion 121.
[0053] In a specific arrangement, the protrusion 144 may extend in a direction away from the substrate 11 (upward in the figure) so that the lower surface of the chip 20 can abut against the upper surface of the protrusion 144. Alternatively, the protrusion 144 may extend toward the substrate 11 so that the upper plate surface of the substrate 11 can abut against the protrusion 144. In other words, the protrusion 144 can increase the height of the support base 14 to increase the minimum distance between the chip 20 and the substrate 11.
[0054] It can be understood that when the second conductive part 122 is an elastic arm structure, the support base 14 can also be positioned under the substrate 11 to ensure a minimum distance between the lower plate surface of the substrate 11 and the main board 30.
[0055] In addition, one support base 14 may be connected to multiple conductive terminals 12 simultaneously to improve the manufacturing convenience of the connector 10 and simplify the assembly process.
[0056] 12, in the embodiment provided in the present application, the support base 14 is a long strip structure, and a plurality of conductive terminals 12 (five conductive terminals are shown in the figure) arranged in a row are fixed to the support base 14. In other words, the plurality of conductive terminals 12 can be fixed in place using a single support base 14, which can effectively improve convenience during manufacturing and assembly.
[0057] In summary, the support base 14 may be secured to only one conductive terminal 12 or to more than one conductive terminal 12 simultaneously.
[0058] In addition, in practical applications, the number of conductive terminals 12 and the positional arrangement of the plurality of conductive terminals 12 can also be appropriately adjusted according to practical requirements.
[0059] In summary, there may be M conductive terminals 12. Correspondingly, M through holes 111 may be arranged on the substrate 11, and the M conductive terminals 12 are arranged in one-to-one correspondence with the M through holes 111. Alternatively, it may be understood that each conductive terminal 12 is fixed to a corresponding through hole 111. The arrangement position of the through holes 111 on the substrate 11 may be flexibly arranged according to actual requirements. In addition, the cross-sectional shape and size of the through holes 111 may also be flexibly selected and adjusted according to actual requirements, which are not limited in the present application.
[0060] In addition, in practical applications, some of the conductive terminals 12 are configured to implement electrical connection between the chip 20 and the main board 30. Some of the conductive terminals 12 need to be further grounded. To facilitate understanding of this technical solution, the conductive terminals 12 configured to implement electrical connection between the chip 20 and the main board 30 may be called signal terminals. The conductive terminals 12 configured to be grounded are called ground terminals.
[0061] In the current connector 10, the ground terminals are grounded separately and do not form a whole ground network, therefore the signal transmission performance of the connector 10 is also degraded.
[0062] For example, Figure 13 shows a case where multiple ground terminals are grounded separately. Obtained in 1 shows a diagram of signal data simulation of connector 10.
[0063] Figure 14 shows , contact When multiple earth terminals are earthed using an earth network (specifically, there is an electrical connection between multiple earth terminals) Obtained in 1 shows a diagram of signal data simulation of connector 10.
[0064] In Figures 13 and 14, the abscissa is the unit Place G hz have is the resonant frequency and the ordinate is the crosstalk.
[0065] In FIG. 13, the resonant frequency of the connector 10 2 8Ghz Nearby 14, the signal crosstalk is about -41 dB. 2 8Ghz Nearby 13 and 14, it can be seen that after the ground terminal is grounded using a grounding network, the resonant frequency of the connector 10 can be significantly increased and the signal crosstalk can be effectively reduced.
