[0025] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] Chip packaging mainly involves integrating the bare die of an integrated circuit chip onto a substrate, and then bringing out all the pins required by the user to form a whole. Existing chip packaging methods include BGA (Ball Grid Array Package), COB (Chips on Board), DIP (dual in-line package), PGA (pin grid array), etc.

[0027] BGA packaging refers to a high-density surface mount packaging technology. At the bottom of the package, the pins are spherical and arranged in a grid-like pattern, and soldered to the circuit board through the spherical pins.

[0028] COB packaging refers to a packaging technology designed to solve the heat dissipation problem of LEDs (light-emitting diodes). The bare chip is adhered to an interconnect substrate with conductive or non-conductive glue, and then bonded to achieve electrical connection between the chip and the circuit board.

[0029] DIP packaging refers to a packaging technology that uses a dual in-line package. The bare chip of the DIP package usually includes at least one row of pins and needs to be inserted into a chip socket with a DIP structure to complete the DIP package.

[0030] PGA packaging means that the pins are located at the bottom of the bare chip, forming a regular grid arrangement for connection to the base or socket.

[0031] However, the packaging methods of the above chips are all single-sided mounting methods. With the development of the market and control circuit systems, more complex circuit requirements and corresponding circuit control logic are required, which leads to a decrease in the product applicability of the chip obtained by the single-sided mounting method. The chip disclosed in the embodiment of the utility model may include a body 1 and a plurality of pins 2, each of which includes an extension portion 21, a first connection portion 22 and a second connection portion 23 arranged on the body 1, the first connection portion 22 and the second connection portion 23 are arranged on the extension portion 21, and the body 1 is electrically connected to the first circuit board 3 through the first connection portion 22, and the body 1 is electrically connected to the second circuit board 4 through the second connection portion 23. In this way, double-sided connection between the chip and the first circuit board 3 and the chip and the second circuit board 4 can be achieved, thereby expanding the design space of the peripheral circuit, reducing the use of the switching circuit, and improving the product applicability of the chip.

[0032] Reference Figure 1-5 An embodiment of the utility model provides a chip, which may include a main body 1 and a plurality of pins 2, wherein each of the pins 2 includes an extension portion 21, a first connection portion 22 and a second connection portion 23 arranged on the main body 1, the first connection portion 22 and the second connection portion 23 are arranged on the extension portion 21, and the main body 1 is electrically connected to a first circuit board 3 through the first connection portion 22, and the main body 1 is electrically connected to a second circuit board 4 through the second connection portion 23.

[0033] In the embodiment of the utility model, the chip may include a body 1 and a plurality of pins 2. Those skilled in the art may specifically determine the number of corresponding pins 2 according to different chip specifications, and no excessive limitation is given here. For example, the number of the pins 2 may include 4, 6, 9, and 12. The pins 2 may be arranged on the side of the body 1, or the pins 2 may also be arranged on the top surface of the body 1, and the pins 2 are used to be electrically connected to other circuit boards.

[0034] For each of the pins 2, the pin 2 may include an extension portion 21, a first connection portion 22 and a second connection portion 23. The extension portion 21 extends from the main body 1, and the first connection portion 22 and the second connection portion 23 are both arranged on the extension portion 21. Among them, the first extension portion 21 is electrically connected to the first circuit board 3, and the second extension portion 21 is electrically connected to the second circuit board 4. Thus, the first circuit board 3, the chip and the second circuit board 4 can be stacked together in sequence. Thereby, double-sided connection between the chip and the first circuit board 3 and between the chip and the second circuit board 4 can be achieved, thereby expanding the design space of the peripheral circuit, reducing the use of the switching circuit, and improving the product applicability of the chip. At the same time, the complexity of the peripheral circuit can also be increased, which is more conducive to the use of the chip in scenarios with complex circuit requirements.

[0035] In summary, the utility model embodiment discloses a chip, the chip may include a body 1 and a plurality of pins 2, each of the pins 2 includes an extension portion 21, a first connection portion 22 and a second connection portion 23 arranged on the body 1, the first connection portion 22 and the second connection portion 23 are arranged on the extension portion 21, and the body 1 is electrically connected to the first circuit board 3 through the first connection portion 22, and the body 1 is electrically connected to the second circuit board 4 through the second connection portion 23. Thus, double-sided connection between the chip and the first circuit board 3 and the chip and the second circuit board 4 can be achieved, thereby expanding the design space of the peripheral circuit, reducing the use of the switching circuit, and improving the product applicability of the chip. At the same time, the complexity of the peripheral circuit can also be increased, which is more conducive to the use of the chip in scenarios with complex circuit requirements.

[0036] An optional utility model embodiment, referring to Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the first connection portion 22 includes a plurality of fixing plates 221 , and the cross-sections of the plurality of fixing plates 221 in the horizontal direction are arranged in a circle, wherein the plurality of fixing plates 221 are embedded in the first circuit board 3 .

[0037] In an embodiment of the utility model, the first connection part 22 may include a plurality of fixing plates 221, wherein the plurality of fixing plates 221 may be understood as a number of at least two fixing plates 221. The cross-sections of the plurality of fixing plates 221 in the horizontal direction are arranged in a common circle. In other words, the cross-section of each fixing plate 221 in the horizontal direction is an arc shape, and the cross-sections of the plurality of fixing plates 221 corresponding to each first connection part 22 in the horizontal direction are on the edge of the same circle. The plurality of fixing plates 221 corresponding to each first connection part 22 may be regarded as being distributed in the shape of petals. Thus, the first connection part 22 may be embedded in the first circuit board 3 through the plurality of fixing plates 221 to form an electrical connection with the first circuit board 3.

[0038] Those skilled in the art may determine the number of fixing plates 221 included in each first connection portion 22 according to actual design requirements. For example, the number of fixing plates 221 included in each first connection portion 22 may be 2, 3, or 4, etc., which is not limited here.

[0039] In other optional embodiments, when the body 1 has a plurality of pins 2, the number of fixing plates 221 corresponding to each pin 2 may be inconsistent. For example, when the body 1 includes 12 pins 2, such as pins P1, P2 to P12, the number of fixing plates 221 corresponding to the pins P1, P6, P7 and P12 may be 4, and the number of fixing plates 221 corresponding to the other pins 2 except the pins P1, P6, P7 and P12 may be 3, and no further limitation is given here.

[0040] Reference Figure 2 As shown, a mounting hole for the fixing plate 221 to pass through is opened on the first circuit board 3. When the first connecting portion 22 and the first circuit board 3 are assembled, the fixing plate 221 can be embedded in the mounting hole so that the fixing plate 221 and the first circuit board 3 are positioned to limit the position and maintain electrical connection.

[0041] In one example, the fixing plate 221 can be made of metal material. Preferably, the fixing plate 221 can be made of copper material. Correspondingly, the extension portion 21 can also be made of metal material, and the second connecting portion 23 can also be made of metal material. As some preferred embodiments, the extension portion 21 can be made of copper material, and the second connecting portion 23 can also be made of copper material.

[0042] In some embodiments, the extension portion 21 and the first connection portion 22 may be fixed by welding, and the extension portion 21 and the second connection portion 23 may be fixed by welding. In other embodiments, the extension portion 21 and the first connection portion 22 may be an integrated structure, and the extension portion 21 and the second connection portion 23 may also be an integrated structure, thereby, the entire pin 2 is designed by integrated molding, which can improve the production convenience of the chip and reduce the production cost of the chip. In addition, the loss in circuit operation can be reduced.

[0043] An optional utility model embodiment, referring to Figure 2 and Figure 4 As shown, the fixing sheet 221 is an elastic sheet. When a plurality of the fixing sheets 221 are embedded in the first circuit board 3 , they form a pressure contact with the first circuit board 3 .

[0044] In the embodiment of the utility model, the fixing sheet 221 may be an elastic sheet. That is to say, the fixing sheet 221 has a deformation property. When the fixing sheet 221 is an elastic sheet, when the multiple fixing sheets 221 corresponding to each first connecting portion 22 are embedded in the first circuit board 3, the outer end surfaces of the multiple fixing sheets 221 that are away from each other respectively form a pressure contact with the hole wall of the mounting hole opened on the first circuit board 3. Thereby, the structural connection stability between the first connecting portion 22 and the first circuit board 3 can be improved, and the electrical connection stability between the first connecting portion 22 and the first circuit board 3 can be further improved.

[0045] The maximum diameter corresponding to the cross section of the plurality of fixing pieces 221 in the horizontal direction is greater than the diameter of the mounting hole opened on the first circuit board 3. Therefore, when the first connection portion 22 and the first circuit board 3 are assembled, the mounting hole on the first circuit board 3 can be made to correspond to the first connection portion 22, and a force is applied to press the first circuit board 3 against the first connection portion 22. When the plurality of fixing pieces 221 enter the mounting hole and move to the point where the maximum diameter corresponding to the cross section of the plurality of fixing pieces 221 in the horizontal direction reaches the opening of the mounting hole, the plurality of fixing pieces 221 are deformed under the pressure of the hole wall of the mounting hole, and the plurality of fixing pieces 221 move radially inward toward each other.

[0046] At the same time, under the limitation of the mounting hole, the plurality of fixing pieces 221 cannot be deformed and restored, so that the deformation force of the plurality of fixing pieces 221 reacts on the hole wall of the mounting hole to form a pressure contact with the first circuit board 3. Thus, the freedom of the first connecting portion 22 and the first circuit board 3 in the radial direction (also referred to as in the horizontal direction) can be limited.

[0047] An optional utility model embodiment, referring to Figure 1 , Figure 3 as well as Figure 4 As shown, a thread 222 is provided on the first connection portion 22 of at least one of the pins 2 , the first connection portion 22 passes through the first circuit board 3 , and the first connection portion 22 and the first circuit board 3 are fixed by a fastener 5 .

[0048] In the embodiment of the utility model, a thread 222 is provided on the first connection portion 22 of at least one of the pins 2. For example, the thread 222 can be provided on the hole wall of the fixing plate 221 close to the mounting hole. Thus, when the first connection portion 22 and the first circuit board 3 are assembled, the first connection portion 22 can be arranged to pass through the mounting hole of the first circuit board 3. In other words, a portion of the fixing plate 221 extends to the outside of the end surface of the first circuit board 3 away from the body 1.

[0049] Thus, the fixing piece 221 located outside the end surface of the first circuit board 3 away from the body 1 can cooperate with the thread 222 on the fixing piece 221 through the fastener 5, so as to limit the axial (also called vertical) freedom of the first connection part 22 and the first circuit board 3. Thus, the pin 2 can be prevented from falling off from the first circuit board 3 due to external force. Thus, the structural connection stability and electrical connection stability between the first connection part 22 and the first circuit board 3 can be guaranteed.

[0050] In some embodiments, the fastener 5 may be a nut; in other embodiments, the fastener 5 may be a component with an internal thread 222 that cooperates with the thread 222 on the fixing plate 221 to form a limit.

[0051] In an optional embodiment of the utility model, the pin 2 with the thread 222 is arranged at the edge position of a plurality of the pins 2 .

[0052] In the embodiment of the utility model, in order to improve the convenience of assembling the chip, the pin 2 with the thread 222 is arranged at the edge of the plurality of pins 2. For example, in the case where the chip has two columns of pins 2, the pin 2 with the thread 222 can be arranged at the edge of each column of pins 2, and can be the first pin 2 corresponding to each column of pins 2, or the last pin 2. This can avoid the problem of low assembly efficiency caused by the need to first find the pin 2 with the thread 222 when there are too many pins 2 during the assembly process of the chip and the circuit board, and then install the fastener 5.

[0053] For example, when the body 1 includes 12 pins 2, such as pins P1, P2 to P12, the 6 pins 2 from pins P1 to P6 are in one row, and the 6 pins 2 from pins 27 to P12 are in one row. Thus, the pins P1, P6, P7 and P12 can all be provided with the thread 222. The number of pins 2 provided with the thread 222 can be at least one. If the number of pins 2 provided with the thread 222 is one, the thread 222 can be provided on one of the pins 2 among the pins P1, P6, P7 and P12.

[0054] If the number of pins 2 provided with the thread 222 is two, the thread 222 may be provided on the pin P1 and the pin P6; the thread 222 may be provided on the pin P1 and the pin P7; the thread 222 may be provided on the pin P1 and the pin P12; the thread 222 may be provided on the pin P6 and the pin P7; the thread 222 may be provided on the pin P6 and the pin P12; the thread 222 may be provided on the pin P7 and the pin P12.

[0055] As a preferred embodiment, the thread 222 may be provided on the pin P1, the pin P6, the pin P7 and the pin P12. Thus, the body 1 may cooperate with the plurality of fasteners 5 through the plurality of threads 222 (located at the four vertices of the body 1) distributed at the edge of the side of the body 1. Thus, the structural connection stability between the first connection portion 22 and the first circuit board 3 may be improved.

[0056] In an optional embodiment of the utility model, the cross-sectional radius of the plurality of fixing plates 221 in the horizontal direction gradually decreases from the middle position of the fixing plate 221 to the direction where the fixing plate 221 is away from the second connecting portion 23 .

[0057] In the embodiment of the utility model, the cross-sectional radius of the plurality of fixing pieces 221 in the horizontal direction gradually decreases from the middle position of the fixing piece 221 to the direction in which the fixing piece 221 is away from the second connection part 23. It can be understood that the plurality of fixing pieces 221 gradually approach the ends away from the second connection part 23 and gather at the center, so that the first connection part 22 can be inserted into the mounting hole on the first circuit board 3 to play a guiding role. Thereby, the assembly convenience between the first connection part 22 and the first circuit board 3 is further improved.

[0058] The middle position of the fixing piece 221 can be understood as the position corresponding to the maximum diameter of the horizontal cross section of the multiple fixing pieces 221. In addition, the forces exerted on the multiple fixing pieces 221 on the same first connecting portion 22 are all directed toward the axis, thereby ensuring that the forces exerted on the fixing pieces 221 are uniform and the structural connection stability between the first connecting portion 22 and the first circuit board 3 is ensured.

[0059] In an optional embodiment of the utility model, a chamfer 231 is provided at an end of the second connection portion 23 away from the first connection portion 22 .

[0060] In the embodiment of the utility model, when the end of the second connecting portion 23 away from the first connecting portion 22, that is, the end close to the second circuit board 4, is provided with a chamfer 231, it can play a guiding role when the second connecting portion 23 is inserted into the welding hole opened on the second circuit board 4, thereby improving the assembly convenience between the second connecting portion 23 and the second circuit board 4.

[0061] An optional utility model embodiment, referring to Figure 5 As shown, the first connection portion 22 and the second connection portion 23 are arranged in parallel.

[0062] In an embodiment of the utility model, the first connecting portion 22 and the second connecting portion 23 can be arranged in parallel, so that when the first connecting portion 22 is electrically connected to the first circuit board 3 and the second connecting portion 23 is electrically connected to the second circuit board 4, the main body 1, the first circuit board 3 and the second circuit board 4 can be arranged in parallel, or the main body 1, the first circuit board 3 and the second circuit board 4 can be stacked in sequence, so as to facilitate the limitation and assembly of the main body 1, the first circuit board 3 and the second circuit board 4 in the vertical direction.

[0063] Reference Figure 5 As shown, the extension part 21 can also be arranged on the side of the body 1 and arranged horizontally, so that the extension part 21 and the first connecting part 22, and the extension part 21 and the second connecting part 23 can be respectively perpendicular. Therefore, during the assembly process of the body 1, the first circuit board 3 and the second circuit board 4, the first connecting part 22 can be used to limit the horizontal installation of the first circuit board 3, and the second connecting part 23 can be used to limit the horizontal installation of the second circuit board 4.

[0064] An optional utility model embodiment, referring to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the first connecting portion 22 and the second connecting portion 23 are coaxially arranged.

[0065] In the embodiment of the utility model, the first connection part 22 and the second connection part 23 are coaxially arranged, which means that the central axis of the first connection part 22 and the central axis of the second connection part 23 coincide with each other. The first connection part 22 and the second connection part 23 can be needle-shaped structures respectively. When the first connection part 22 and the second connection part 23 are coaxially arranged, it is more convenient to form the first connection part 22 and the second connection part 23 in one piece, thereby reducing the production cost of the chip.

[0066] An optional utility model embodiment, referring to Figure 3 and Figure 4 As shown, the second connecting portion 23 is fixed to the second circuit board 4 by welding.

[0067] In the embodiment of the utility model, a welding hole is opened on the second circuit board 4 , and the second connecting portion 23 can be embedded in the welding hole and fixed to the second circuit board 4 by welding.

[0068] When assembling the second connection part 23 and the second circuit board 4, the pins 2 on the chip can be inserted into the welding holes provided on the second circuit board 4, and the second connection part 23 and the second circuit board 4 can be welded on the end surface of the second circuit board 4 away from the chip. Among them, the connection method between the second circuit board 4 and the second connection part 23 can be regarded as a mounting method, so that the structural function of the chip of the bottom mounting and the top connection can be realized. It can also expand the design space of the peripheral circuit, reduce the use of the switching circuit, and improve the product applicability of the chip. At the same time, it can also increase the complexity of the peripheral circuit, which is more conducive to the use of the chip in the scene of complex circuit requirements.

[0069] In summary, the utility model embodiment discloses a chip, the chip may include a body 1 and a plurality of pins 2, each of the pins 2 includes an extension portion 21, a first connection portion 22 and a second connection portion 23 arranged on the body 1, the first connection portion 22 and the second connection portion 23 are arranged on the extension portion 21, and the body 1 is electrically connected to the first circuit board 3 through the first connection portion 22, and the body 1 is electrically connected to the second circuit board 4 through the second connection portion 23. Thus, double-sided connection between the chip and the first circuit board 3 and the chip and the second circuit board 4 can be achieved, thereby expanding the design space of the peripheral circuit, reducing the use of the switching circuit, and improving the product applicability of the chip. At the same time, the complexity of the peripheral circuit can also be increased, which is more conducive to the use of the chip in scenarios with complex circuit requirements.

[0070] During the assembly process of the chip and the circuit board, the chip and the second circuit board 4 can be assembled in advance. For example, the pins 2 (second connecting parts 23) on the chip can be inserted into the welding holes opened on the second circuit board 4, and the second connecting parts 23 and the second circuit board 4 can be welded on the end surface of the second circuit board 4 away from the chip.

[0071] Then, the chip and the first circuit board 3 are assembled. For example, the fixing plate 221 can be embedded in the mounting hole provided on the first circuit board 3, so that the fixing plate 221 and the first circuit board 3 form a position limit. In addition, a portion of the fixing plate 221 extends to the outside of the end surface of the first circuit board 3 away from the body 1. Thus, the fixing plate 221 located outside the end surface of the first circuit board 3 away from the body 1 can cooperate with the thread 222 on the fixing plate 221 through the fastener 5, so as to limit the axial (also referred to as vertical) degree of freedom of the first connecting portion 22 and the first circuit board 3. Thereby, the pin 2 can be prevented from falling off from the first circuit board 3 due to external force. The structural connection stability and electrical connection stability between the first connecting portion 22 and the first circuit board 3 can be guaranteed.

[0072] At the same time, a part of the fixing sheet 221 is located in the mounting hole, and the plurality of fixing sheets 221 are deformed under the pressure contact force of the hole wall of the mounting hole, and the plurality of fixing sheets 221 move radially inward toward each other. Under the limitation of the mounting hole, the plurality of fixing sheets 221 cannot recover from deformation, and thus, the deformation force of the plurality of fixing sheets 221 reacts to the hole wall of the mounting hole, forming a pressure contact with the first circuit board 3. Thus, the freedom of the first connecting portion 22 and the first circuit board 3 in the radial direction (also referred to as in the horizontal direction) can be limited. When the length of the fixing sheet 221 extending out of the end face of the first circuit board 3 away from the main body 1 reaches a preset length, or the first circuit board 3 conflicts with the extension portion 21, the fastener 5 can be assembled from the first circuit board 3.

[0073] In summary, the utility model embodiment discloses a chip, the chip may include a body 1 and a plurality of pins 2, each of the pins 2 includes an extension portion 21, a first connection portion 22 and a second connection portion 23 arranged on the body 1, the first connection portion 22 and the second connection portion 23 are arranged on the extension portion 21, and the body 1 is electrically connected to the first circuit board 3 through the first connection portion 22, and the body 1 is electrically connected to the second circuit board 4 through the second connection portion 23. Thus, double-sided connection between the chip and the first circuit board 3 and the chip and the second circuit board 4 can be achieved, thereby expanding the design space of the peripheral circuit, reducing the use of the switching circuit, and improving the product applicability of the chip. At the same time, the complexity of the peripheral circuit can also be increased, which is more conducive to the use of the chip in scenarios with complex circuit requirements.

[0074] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] It is easy for a person skilled in the art to think that any combination of the above embodiments is feasible, so any combination of the above embodiments is an implementation scheme of the present utility model. However, due to space limitations, this specification will not describe them in detail here.
