Precise positioning plate for chip test seat

Abstract

A precision positioning plate of a chip test seat comprises a circuit board groove, a fixing hole 1, a fixing hole 2, a positioning column 1, a positioning column 2, a fixing hole 3, a positioning ring 1, a displacement groove 1, a positioning ring 2, a displacement groove 2, a wire passing hole and a fixing hole 4. The thin strip 1, the thin strip 2, the thin strip 3 and the thin strip 4 are arranged in sequence. The thin strip 1, the thin strip 2, the thin strip 3 and the thin strip 4 can move slightly under the action of external force. When the positioning ring 1 needs to move rightwards, a screwdriver is inserted into the left side of the positioning ring 1 to prize the positioning ring 1, and the thin strip 1 generates tiny plastic deformation, so that the positioning ring 1 generates required tiny movement rightwards. Similarly, the positioning ring 1 is moved leftwards; and the positioning ring 1 is moved downwards. And the shifting groove 1 is pried to move the positioning ring 1 upwards. In the same way, the positioning ring (2) generates a desired movement. The method has the advantages that the requirement that the machining precision is within the limit range of a common machining enterprise is met, and the pin probe and the chip pin bonding pad can be accurately paired by finely adjusting the position of the positioning ring of the precision positioning plate of the chip testing seat.

Description

(I) Technical field

[0001] The invention relates to the technical field of chip testing, and in particular to a chip testing seat precision positioning plate. (II) Background technology

[0002] Semiconductor chips can only be used after aging and testing. Aging and testing of chips are generally performed using chip test sockets. The development direction of mainstream chips today is that the number of pins is increasing, the chip area is getting smaller, and the pin spacing is getting smaller. The positioning and fixation of the PCB is completed by the positioning plate, which has positioning holes. The alignment of the pin probe in the chip test socket with the chip pin pad is completed by the positioning holes on the positioning plate and the positioning columns in the test socket. The accuracy requirements of the positioning holes are very high, which has exceeded the limits of many processing companies.

[0003] For this purpose, it is necessary to develop a chip test seat precision positioning board to meet the processing accuracy within the limit range of general processing enterprises. By fine-tuning the position of the positioning holes of the chip test seat precision positioning board, the pin probe and the chip pin pad can be accurately matched. (III) Summary of the invention

[0004] The purpose of the present invention is to develop a chip test seat precision positioning plate, which can meet the processing accuracy within the limit range of general processing enterprises, and can achieve the purpose of precise matching of pin probes and chip pin pads by fine-tuning the position of positioning holes of the chip test seat precision positioning plate.

[0005] To achieve the above purpose, the chip test seat precision positioning plate proposed by the present invention includes: a circuit board slot, a fixing hole 1, a fixing hole 2, a positioning column 1, a positioning column 2, a fixing hole 3, a positioning ring 1, a displacement slot 1, a positioning ring 2, a displacement slot 2, a wire hole, and a fixing hole 4. Thin strips 1, 2, 3, and 4. Thin strips 1, 2, 3, and 4 can move slightly under the action of external force.

[0006] When the positioning ring 1 needs to be moved to the right, insert a screwdriver into the left side of the positioning ring 1 and pry it. The thin strip 1 will produce a slight plastic deformation, so that the positioning ring 1 will produce the required slight movement to the right. Similarly, move the positioning ring 1 to the left; move the positioning ring 1 downward. Pry the shift slot 1 to move the positioning ring 1 upward. In the same way, the positioning ring 2 will produce the required movement.

[0007] Compared with the prior art, the beneficial effects of the present invention are: a chip test seat precision positioning plate, which meets the processing accuracy within the limit range of general processing enterprises, and can achieve the purpose of precise matching of pin probes and chip pin pads by fine-tuning the position of the positioning ring of the chip test seat precision positioning plate.

(V) Specific implementation methods

[0011] Refer to the attached Figure 1 , Attachment Figure 2 The chip test seat precision positioning plate has a circuit board slot (1) for placing a circuit board. The circuit board slot (1) has two fixing holes: fixing hole 1 (2) and fixing hole 2 (3); and two positioning posts: positioning post 1 (4) and positioning post 2 (5). Four fixing holes 3 (6) are larger than the screws used for fixing, so that when the positioning ring 1 (7) and the positioning ring 2 (9) move, the fixing screws can still be used for fixing. The positioning ring 1 (7) and the positioning ring 2 (9) are connected to the chip test seat precision positioning plate by thin strips 1 (71), thin strips 2 (81), thin strips 3 (91) and thin strips 4 (101). The thin strips 1 (71), thin strips 2 (81), thin strips 3 (91) and thin strips 4 (101) can move slightly under the action of external force.

[0012] When the positioning ring 1 (7) needs to be moved to the right, insert a screwdriver into the left side of the positioning ring 1 (7) and pry it. The thin strip 1 (71) will produce a slight plastic deformation, so that the positioning ring 1 (7) will produce the required slight movement to the right. Similarly, move the positioning ring 1 (7) to the left; move the positioning ring 1 (7) downward. Pry the displacement groove 1 (8) to move the positioning ring 1 (7) upward. In the same way, the positioning ring 2 (9) will produce the required movement. In this way, the positioning ring 1 (7) and the positioning ring 2 (9) can be accurately positioned.
