Description

Technical Field

[0001] This invention relates to the field of semiconductor integrated circuit manufacturing, and in particular to a jumper board connection device. Background Technology

[0002] In existing traditional jumper board connection devices, the jumper board pins are connected to the base by soldering to achieve current flow. Depending on the testing requirements of different test structures, different jumpers need to be replaced on the jumper board to adjust the equipment's operating status. However, removing or replacing jumpers applies upward stress to the base. While soldering is a simple process, it is not very secure and can easily lead to jumper detachment during removal, severely impacting the lifespan of the testing equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a jumper board connection device that can securely fix the jumper board and thus prevent the pins from falling off when the jumper is removed.

[0004] To solve the above-mentioned technical problems, the jumper board connection device provided by the present invention includes: pins disposed on the bottom surface of the jumper board and contacts disposed on the base.

[0005] The pin has a tenon-shaped structure.

[0006] The contact foot has a first groove for the insertion of the pin, and a mortise structure on the side corresponding to the first groove that engages with the tenon structure.

[0007] When the jumper board and the base are connected, the pin is inserted into the first groove of the contact pin and makes contact through the interlocking of the tenon structure and the mortise structure, thereby fixing the jumper board and the base vertically.

[0008] A further improvement is that, in the state where the tenon structure and the mortise structure are engaged, the first groove outside the tenon structure is fixed by soldering to prevent the jumper board from wobbling left and right.

[0009] A further improvement is that a jumper connector is provided on the top surface of the jumper board, and the bottom of the jumper connector passes through the jumper board and connects to the pin.

[0010] The jumper connector pin is used for jumper connection.

[0011] A further improvement is that the contacts on the base are used to connect to the electrical terminals of the chip under test or the test signal interface of the test equipment.

[0012] A further improvement is that the connection relationship between the jumper board and the jumper is switched according to the testing requirements of the chip under test.

[0013] A further improvement is that the testing equipment includes an EM device.

[0014] A further improvement is that, in the pin, the tenon structure includes a first protrusion disposed on the first side of the first strip structure.

[0015] A further improvement is that the mortise structure includes a second groove disposed on a first side of the first groove; the second groove is used to place the first protrusion.

[0016] A further improvement is that, in a top view, the first strip structure is square.

[0017] A further improvement is that, on the top view, the first protrusion is square and the second groove is square.

[0018] A further improvement is that the bottom surface of the first protrusion is flush with the bottom surface of the first strip structure, the second side of the first protrusion is in contact with the first side of the first strip structure, and the width of the second side is less than or equal to the width of the second side.

[0019] A further improvement is that the pins are made of metal and fixed to the jumper board.

[0020] The tentacles are made of metal and are fixed to the base.

[0021] This invention features a specially designed structure for the interconnecting pins and contacts, incorporating tenon-shaped structures on the pins and mortise-shaped structures on the contacts. The interlocking of these tenon and mortise structures effectively secures the jumper board and base vertically, preventing pins from detaching due to upward pulling forces during jumper removal. Furthermore, the invention allows for soldering within the grooves between the pins and contacts, further preventing lateral movement. Therefore, this invention provides a secure fixation of the jumper board, preventing pin detachment during jumper removal and thus extending the lifespan of the testing equipment.
