Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to a test board. Background Technology

[0002] The convenient and directional aging test board is a carrier for aging tests on chips or other electrical components in electronic devices. Its reasonable structural layout can ensure stable and reliable operation for a long time, and also determines the accuracy, safety and convenience of the test.

[0003] The convenient guide-type aging test board includes a motherboard and mounting components. Before testing, the chip needs to be installed on the mounting components. After testing, the chip needs to be removed from the mounting components. The mounting components have mounting slots and latches. When the chip is installed in the mounting slot, it can be latched by the latches. Whether installing or removing the chip from the mounting slot, the operating part of the latches needs to be pressed down to keep the latches outside the path of the chip entering or leaving the mounting slot. However, pressing down will cause the motherboard to bend downward, which may damage the motherboard itself or the components on the underside of the motherboard and affect its service life. At the same time, the bent motherboard causes the chip mounting angle to change, increasing the installation difficulty.

[0004] Therefore, there is an urgent need to develop a test board to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a test board to solve the problem in the prior art where chip removal and installation causes the motherboard to bend, thereby affecting its service life and increasing the difficulty of installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Test board, including:

[0008] frame;

[0009] A first circuit board is disposed on the frame. The first circuit board has a first plate surface and a second plate surface that are arranged opposite each other in the vertical direction. The first plate surface has a mounting assembly that can be plugged into and mated with the component under test.

[0010] A first support member is disposed on the second surface of the first circuit board and located below the mounting assembly, and the first support member protrudes from the second surface.

[0011] As an optional technical solution for the test board, the first board surface of the first circuit board is provided with a first connector; the mounting assembly has a second connector, and the first connector and the second connector are plugged into each other; the test board further includes a second support member, which is disposed on the first board surface of the first circuit board, and the second support member supports the mounting assembly when the first connector and the second connector are plugged into each other.

[0012] As an optional technical solution for a test board, the mounting assembly includes a second circuit board and a mounting base. The mounting base is disposed on the second circuit board and is used to mount the component under test. The second connector is disposed on the side of the second circuit board away from the mounting base. The second support member can support the second circuit board and is disposed corresponding to the mounting base.

[0013] As an optional technical solution for the test board, at least two first connectors and at least two second connectors are provided, each corresponding to one of the two first connectors. The two first connectors are arranged at intervals, and the second support is located between the two first connectors.

[0014] As an optional technical solution for the test board, the second support includes an edge support portion near the first connector and an intermediate support portion extending horizontally from the edge support portion, with the ends of the edge support portion and the intermediate support portion aligned vertically.

[0015] As an optional technical solution for the test board, the first support member and the second support member have the same structure and are arranged correspondingly in the vertical direction.

[0016] As an optional technical solution for the test board, both the first support member and the second support member are screwed to the mounting assembly.

[0017] As an optional technical solution for the test board, the first support and the second support are made of the same material, and the hardness of the first support and the second support is greater than that of the first circuit board.

[0018] As an optional technical solution for a test board, the frame includes two longitudinal support rods extending along a first direction and at least two transverse support rods extending along a second direction perpendicular to the first direction. The two longitudinal support rods are spaced apart along the second direction, and the at least two transverse support rods are spaced apart along the first direction. One end of each transverse support rod is connected to one of the two longitudinal support rods, and the other end of each transverse support rod is connected to the other of the two longitudinal support rods.

[0019] As an optional technical solution for the test plate, the test plate further includes two wear-resistant components spaced apart on the second plate surface. The bottom of the two wear-resistant components forms a support surface, and the two opposite surfaces of the two longitudinal support rods respectively form two limiting surfaces. The frame can slide and engage with the slide groove of the test mechanism. The support surface is used to support the test plate in the vertical direction, and the two limiting surfaces are used to limit the displacement of the frame relative to the test mechanism in the second direction.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a test board, which includes a frame, a first circuit board, and a first support member. The first circuit board is mounted on the frame, and its first surface has a mounting assembly that can connect to and interlock with the component under test. The first support member is mounted on the second surface of the first circuit board and protrudes from it. This allows the test board to be placed on a platform during chip placement and removal, where it is supported by the first support member. This prevents the first circuit board from bending when the mounting assembly is pressed, thus preventing the electrical components on the second surface from contacting the platform. This facilitates the application of force during pressing and improves operability and convenience. At the same time, the first circuit board does not deform, ensuring the ease of chip installation.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] like Figures 1 to 6 As shown, this embodiment provides a test board, which includes a frame 100, a first circuit board 200, and a first support member 300. The first circuit board 200 is disposed on the lower side of the frame 100. The first circuit board 200 has a first plate surface 201 and a second plate surface 202 disposed opposite to each other in the vertical direction. The first plate surface 201 has a mounting assembly 1000 that can be plugged into and cooperate with the component under test. The first support member 300 is disposed on the second plate surface 202 of the first circuit board 200 and is located below the mounting assembly 1000. The first support member 300 protrudes from the second plate surface 202.

[0041] In use, the second surface 202 of the first circuit board 200 is at the bottom, and the first surface 201 is at the top. When installing the component under test, it is necessary to press against the mounting assembly 1000, so that the first circuit board 200 is subjected to a downward force. With the help of the first support member 300, the test board can be placed on the platform during the chip loading and unloading process. In this state, the first circuit board 200 is supported by the first support member 300. When pressing the mounting assembly 1000, the first circuit board 200 will not bend, so that the electrical components of the second surface 202 will not come into contact with the platform, which facilitates the application of force when pressing and improves operability and convenience. At the same time, the first circuit board 200 does not deform, ensuring the convenience of chip installation.

[0042] Combination Figure 2 and Figure 4As shown, to facilitate electrical and / or communication connections between the first circuit board 200 and the mounting assembly 1000, in some embodiments, the first board surface 201 of the first circuit board 200 is provided with a first connector 210; the mounting assembly 1000 has a second connector 1110, and the first connector 210 and the second connector 1110 are plugged into each other; the test board also includes a second support member 400, which is disposed on the first board surface 201 of the first circuit board 200, and the second support member 400 supports the mounting assembly 1000 when the first connector 210 and the second connector 1110 are plugged into each other. This design allows the mounting component 1000 to be limited by the second support member 400 during installation on the first circuit board 200, preventing over-fitting that could damage the first connector 210 or the second connector 1110. In addition, during chip placement and removal, when the mounting component 1000 is pressed, the pressing force is transmitted to the first circuit board 200 through the second support member 400, and then to the platform through the first support member 300, ensuring that the first circuit board 200 does not deform while preventing damage to the first connector 210 and the second connector 1110.

[0043] To achieve electrical and / or communication connections between the device under test (DUT) and the first circuit board 200, in some embodiments, the mounting assembly 1000 includes a second circuit board 1100 and a mounting base 1200. The mounting base 1200 is disposed on the second circuit board 1100 and used to mount the DUT. A second connector 1110 is disposed on the side of the second circuit board 1100 away from the mounting base 1200. A second support member 400 supports the second circuit board 1100 and is disposed corresponding to the mounting base 1200. This configuration allows the DUT to be mounted and electrically and / or communicationally connected to the mounting base 1200. The mounting base 1200 is electrically and / or communicationally connected to the second circuit board 1100. The second circuit board 1100 and the first circuit board 200 are electrically and / or communicationally connected via the first connector 210 and the second connector 1110. During testing, the first circuit board 200 is electrically and / or communicationally connected to the testing mechanism via gold fingers 230. The pressure is sequentially transferred through the mounting base 1200, the second circuit board 1100, the second support 400, the first support 300, and the first circuit board 200, and finally delivered to the platform. The first circuit board 200 is equipped with a heat sink 220 to dissipate heat during testing.

[0044] Both the first support member 300 and the second support member 400 are screwed to the mounting assembly 1000. In some embodiments, to achieve a fixed connection between the second support member 400 and the mounting base 1200, the mounting base 1200 has a first screw hole, the second circuit board 1100 has a first through hole, and the second support member 400 has a first fixing hole 410. A first screw passes through the first fixing hole 410 and the first through hole and is screwed into the first screw hole.

[0045] At least two first connectors 210 and at least two second connectors 1110 are provided, each corresponding to one of the two first connectors 210. The two first connectors 210 are arranged at intervals, and the second support member 400 is located between the two first connectors 210. This arrangement allows one second support member 400 to simultaneously protect both the two first connectors 210 and the two second connectors 1110. In addition, the second support member 400, located between the two first connectors 210, has a smaller size, saving costs.

[0046] To achieve a fixed connection between the first support member 300 and the mounting base 1200, combined with Figure 2 and Figure 4 As shown, the first support member 300 has a second fixing hole 310, the first circuit board 200 has a second through hole 240, the second support member 400 has a third fixing hole 420, the second circuit board 1100 has a third through hole 1120, and the mounting base 1200 has a second screw hole 1210. A second screw passes through the second fixing hole 310, the second through hole 240, the third fixing hole 420, and the third through hole 1120 in sequence and is screwed into the second screw hole 1210. By screwing the first support member 300 and the second support member 400 together onto the mounting base 1200, the first circuit board 200 and the second circuit board 1100 can be clamped together, making the test board a single unit and facilitating overall transfer.

[0047] The second support member 400 includes an edge support portion 401 near the first connector 210 and a middle support portion 402 extending horizontally from the edge support portion 401. The ends of the edge support portion 401 and the middle support portion 402 are flush with each other in the vertical direction. In other words, the top surface and bottom surface of the entire second support member 400 are on the same plane. For example, the outline of the top view of the second support member 400 is I-shaped or W-shaped.

[0048] To facilitate processing and maintenance, the first support member 300 and the second support member 400 have identical structures and are arranged correspondingly in the vertical direction. This arrangement reduces mold opening and production costs and improves interchangeability. In this embodiment, the first fixing hole 410, the second fixing hole 310, and the third fixing hole 420 are all smooth holes.

[0049] In some embodiments, the first support member 300 and the second support member 400 are made of the same material, and the hardness of the first support member 300 and the second support member 400 is greater than that of the first circuit board 200, so as to provide support with sufficient strength.

[0050] Combination Figure 6As shown, in some embodiments, the frame 100 includes two longitudinal support rods 110 extending along a first direction and at least two transverse support rods 120 extending along a second direction perpendicular to the first direction. The two longitudinal support rods 110 are spaced apart along the second direction, and the at least two transverse support rods 120 are spaced apart along the first direction. One end of each transverse support rod 120 is connected to one of the two longitudinal support rods 110, and the other end of each transverse support rod 120 is connected to the other of the two longitudinal support rods 110. The vertical direction is the up-down direction, the first direction is the front-back direction, and the second direction is the left-right direction. For example, there are four transverse support rods 120, which are spaced apart along the first direction between the two longitudinal support rods 110 to provide support for the first circuit board 200.

[0051] To ensure smooth docking of the test plate with the testing mechanism during the testing process, in some embodiments, the test plate further includes two wear-resistant components 500 spaced apart on the second plate surface 202. The bottom of the two wear-resistant components 500 forms a support surface 510, and the two opposing surfaces of the two longitudinal support rods 110 respectively form two limiting surfaces 111. The frame 100 can slide and engage with the groove of the testing mechanism. The support surface 510 is used to support the test plate in the vertical direction, and the two limiting surfaces 111 are used to limit the displacement of the frame 100 relative to the testing mechanism in the second direction. The above arrangement constrains the movement path of the test plate, thereby enabling smooth sliding and engagement with the groove of the testing mechanism.

[0052] To facilitate the reciprocating motion of the push-pull test plate in the sliding groove of the testing mechanism, in some embodiments, the frame 100 further includes a grip 130, which is disposed on the outermost transverse support rod 120. The grip 130 is located in the middle of the transverse support rod 120 to improve the balance of force distribution. Exemplarily, the grip 130 is a U-shaped force-applying handle.

[0053] In some embodiments, the end of the frame 100 away from the gripper 130 is provided with a positioning hole 140, which can be inserted and engaged with a positioning pin on the testing mechanism. This arrangement ensures that the gold finger 230 is precisely aligned with the mating part on the testing mechanism, avoiding the risk of wear and breakage of the gold finger 230 during repeated insertions.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
