Description

Technical Field

[0001] The present invention relates to the technical field of silicon board detection, and in particular to a test fixture for detecting a silicon adapter board. Background Art

[0002] Silicon interposer, also known as the middle layer or interposer, usually refers to the functional layer of interconnection and pin redistribution between the chip and the packaging substrate. At present, silicon interposers are mainly made of silicon-based materials. Silicon is used as an interposer and TSV (Through Silicon Via) is used as a line interconnection tool to make the integrated system smaller, more power-efficient, and have higher bandwidth. In order to improve production efficiency, each silicon interposer will eventually be processed into multiple circuit boards. In the prior art, a V-groove is cut on the silicon interposer, and then the circuit board is divided into multiple small boards by breaking.

[0003] During the processing of silicon adapter boards, virtual disconnection and shorting of the metal redistribution layer (RDL) on the same layer of the substrate, or virtual disconnection and shorting between the interlayer via (Via) and the RDL, are common. This type of silicon adapter board is difficult to identify during the inspection before assembly, and is very likely to flow into the module assembly production process line, leaving hidden dangers to the reliability of the module product. It is necessary to add a continuity test link before the silicon adapter board is used for assembly, and both open circuit defects and short circuit defects need to be checked through testing.

[0004] Since the silicon plate with V-grooves is difficult to position during testing, it is easy to be squeezed and broken when the fixture is positioned; in addition, since the silicon plate is thin, and there is a gap between the clamping position of the fixture and the table top, the edge of the silicon plate is easy to get stuck in the gap when clamping; and since there are many small boards that need to be tested on each silicon plate, it is easy to forget the position of the small board that has been tested when recording in the middle, which brings inconvenience. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a test fixture for silicon adapter board detection.

[0009] Preferably, a guide plate is fixedly connected to the front end of the movable plate, and the guide plate is slidably sleeved in front of the operating plate.

[0010] Preferably, the transverse and longitudinal sliding mechanism includes a concave frame fixedly connected to the upper surface of the movable plate, two longitudinal rods are fixedly connected to the inner side of the concave frame, and the outer surfaces of the two longitudinal rods are slidably sleeved with a longitudinal sliding block, one side of the longitudinal sliding block is fixedly connected to an L-shaped frame, two transverse rods are fixedly connected to the inner side of the L-shaped frame, and the outer surfaces of the two transverse rods are slidably sleeved with a transverse sliding block, and the rear end of the connecting frame is fixedly connected to the front surface of the transverse sliding block.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 9 A test fixture for silicon adapter board detection is shown, including a base 1, the upper surface of the base 1 is connected to an operating plate 6 through a rotating mechanism, movable plates 7 are respectively arranged on both sides of the upper surface of the operating plate 6, and distance adjustment mechanisms are arranged at the rear ends of the two movable plates 7. The adjacent sides of the two movable plates 7 are respectively fixedly connected with a plurality of grid plates 8, and the grid plates 8 on both sides are staggered. The staggered distribution design can make the silicon plate body 30 still be supported in the largest possible area when placed, the upper surface of the movable plate 7 on one side is connected to a connecting frame 21 through a horizontal and vertical sliding mechanism, and one side surface of the connecting frame 21 is fixedly connected to an upper plate 22, the lower surface of the upper plate 22 is connected to a lower plate 23 through a lifting mechanism, and the front end of the lower plate 23 is fixedly connected to an indicator frame 24.

[0030] The rotating mechanism includes a raised seat 2 fixedly mounted on the upper surface of the base 1, a servo motor 3 fixedly embedded on the upper surface of the raised seat 2, a spline shaft 4 fixedly connected to the output shaft of the servo motor 3, a spline cylinder 5 fixedly connected to the lower surface of the operating panel 6, and the spline cylinder 5 slidably sleeved on the outer surface of the spline shaft 4. This part of the design facilitates the disassembly and maintenance of the operating panel 6. By lifting the operating panel 6, the spline cylinder 5 can be separated from the surface of the spline shaft 4, which is convenient for operation. The servo motor 3 can control the rotation of the operating panel 6, which is convenient for replacing the edge to continue the detection after detecting one side of the silicon plate body 30.

[0031] The distance adjustment mechanism includes a fixed seat 11 fixedly connected to the back of the operating plate 6, a screw rod 12 is rotatably penetrated inside the fixed seat 11, one end of the screw rod 12 is fixedly connected to a polygonal block 13, and a distance adjustment plate 10 is fixedly connected to the rear end of the movable plate 7, the distance adjustment plate 10 is slidably sleeved behind the operating plate 6, and the screw rod 12 is threadedly penetrated inside the operating plate 6. The polygonal block 13 is convenient for the user to rotate the screw rod 12, and the threads on the surface of the screw rod 12 are bilaterally symmetrical, and when rotating, the two distance adjustment plates 10 will move closer to or farther from each other.

[0032] The front end of the moving plate 7 is fixedly connected with a guide plate 9, and the guide plate 9 is slidably sleeved in front of the operating plate 6. The guide plate 9 is used to improve the stability of the moving plate 7 when it moves.

[0033] The horizontal and vertical sliding mechanism includes a concave frame 14 fixedly connected to the upper surface of the moving plate 7, two longitudinal rods 15 are fixedly connected to the inner side of the concave frame 14, and the outer surfaces of the two longitudinal rods 15 are slidably sleeved with a longitudinal slider 16, one side of the longitudinal slider 16 is fixedly connected to an L-shaped frame 19, and two transverse rods 17 are fixedly connected to the inner side of the L-shaped frame 19, and the outer surfaces of the two transverse rods 17 are slidably sleeved with a transverse slider 20, and the rear end of the connecting frame 21 is fixedly connected to the front surface of the transverse slider 20. When the indicator frame 24 moves forward and backward, the longitudinal slider 16 will slide forward and backward along the surface of the longitudinal rod 15, and when the indicator frame 24 moves horizontally, the transverse slider 20 moves horizontally along the surface of the transverse rod 17.

[0034] A reinforcing plate 18 is fixedly connected to the upper surface of the L-shaped frame 19 , and the reinforcing plate 18 is used to enhance the strength of the L-shaped frame 19 to prevent the L-shaped frame 19 from being deformed due to excessive overturning moment.

[0035] The lifting mechanism includes a guide rod 25 fixedly connected to the front end of the upper surface of the lower plate 23, the upper end of the guide rod 25 slides through the inner side of the upper plate 22, and a threaded rod 26 is rotatably connected to the rear end of the upper surface of the lower plate 23. The upper end of the threaded rod 26 is threaded through the inner side of the upper plate 22, and a screw head 27 is fixedly connected to the upper end of the threaded rod 26. The screw head 27 facilitates the user to rotate the threaded rod 26, and the guide rod 25 is used to improve the stability of the lower plate 23 when it moves up and down.

[0036] The lower end of the threaded rod 26 is fixedly connected with a rotating disk 29, and the upper surface of the lower plate 23 is fixedly connected with a limiting sleeve 28, the rotating disk 29 is rotatably embedded in the inner side of the limiting sleeve 28, and the threaded rod 26 rotates through the upper surface of the limiting sleeve 28. The limiting sleeve 28 plays a limiting role, so that the threaded rod 26 can rotate relative to the lower plate 23, and the lower end of the threaded rod 26 will not separate from the surface of the lower plate 23.

[0037] When in use, the silicon plate body 30 is placed on the upper surface of the grid plate 8. Then, by rotating the screw rod 12, the distance adjustment plates 10 on both sides are moved closer to each other until the movable plates 7 on both sides are respectively attached to the two side edges of the silicon plate body 30, thereby achieving the limiting function of the silicon plate body 30. Since the grid plates 8 on both sides are staggered, it is ensured that the lower surface of the silicon plate body 30 is stably supported, and the silicon plate body 30 is effectively prevented from breaking due to the V-shaped opening 31 on the surface. At the same time, because the grid plate 8 is connected to the movable plate 7, the edge of the silicon plate body 30 will not fall into the gap between the movable plate 7 and the operating plate 6.

[0038] During the detection process, since the silicon board body 30 is composed of a number of small boards distributed in an array, each small board needs to be detected step by step during the detection. During the detection, the indicator frame 24 is moved accordingly to the top of the small board to be detected, and the detection connector is passed through the indicator frame 24 to perform circuit detection on the small board. After the detection is completed, the adjacent small boards are detected one by one by moving horizontally or forward and backward. During this process, due to the existence of the indicator frame 24, the detection position can be effectively recorded to prevent the problem of pausing and recording at a certain small board and remembering the wrong position of the corresponding small board when detecting again, which plays a good indicating role.

[0039] The user rotates the screw head 27 to rotate the threaded rod 26, thereby causing the lower plate 23 to approach or move relative to the upper plate 22, so as to change the distance between the indicator frame 24 and the silicon plate body 30. Without scratching the surface of the silicon plate body 30, the user can get as close to the surface of the silicon plate body 30 as possible, so that the user can pass the detection connector through the indicator frame 24 to detect the small board, thereby bringing convenience to the detection.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
