CN-224218791-U - Prevent rubbing and hinder aluminium silk bonding anchor clamps

Abstract

The utility model relates to a bonding fixture, in particular to an anti-scratch aluminum wire bonding fixture, which comprises a base, wherein a plurality of T-shaped fixing plates which are distributed in parallel are arranged on the upper surface of the base, a plurality of strip-shaped blocks which are uniformly distributed along the length direction of the T-shaped fixing plates are arranged at the tops of the T-shaped fixing plates, positioning grooves are formed between two adjacent strip-shaped blocks, an adhesion layer is arranged in each positioning groove, and the upper surface of each adhesion layer is lower than the upper surface of each strip-shaped block. Through setting up T type fixed plate, rethread adhesion layer is fixed in the top of T type fixed plate with the tube shell, because the pin of tube shell can not directly contact with T type fixed plate, can avoid causing the risk of tube shell pin damage or deformation at the in-process of fixed tube shell.

Description

Prevent rubbing and hinder aluminium silk bonding anchor clamps Technical Field The utility model relates to a bonding clamp, in particular to an anti-scratch aluminum wire bonding clamp. Background The aluminum wire bonding machine realizes electric interconnection between chips and the substrate and information intercommunication between chips by tightly bonding the metal leads with the bonding pads on the substrate or the frame by using thin metal wires. DIP is an integrated circuit dual in-line package, which is rectangular in shape, with two parallel rows of metal pins on each side to form a pin header. When the circuit is fixed, the pin header is required to be inserted into the DIP matrix fixture. The existing DIP matrix fixture is made of aluminum alloy, has relatively high hardness, can scratch or scratch the inside of the pins during plugging, can deform the pins when severe, and causes the appearance of the product to be inconsistent with the standard, and the bonding yield is low. Disclosure of utility model The utility model aims to solve the technical problems that the inside of a pin is scratched or scratched when the existing clamp is plugged and pulled, and the pin is deformed when the existing clamp is severe, and provides an anti-scratch aluminum wire bonding clamp. In order to solve the technical problems, the technical solution provided by the utility model is as follows: An anti-scratch aluminum wire bonding clamp comprises a base, wherein a plurality of T-shaped fixing plates which are distributed in parallel are arranged on the upper surface of the base; the top of the T-shaped fixing plate is provided with a plurality of strip-shaped blocks uniformly distributed along the length direction of the T-shaped fixing plate; A positioning groove is formed between two adjacent strip-shaped blocks, an adhesion layer is arranged in the positioning groove, and the upper surface of the adhesion layer is lower than the upper surface of each strip-shaped block. Further, a plurality of mounting grooves which are distributed in parallel and have the same number as the T-shaped fixing plates are formed in the upper surface of the base; the T-shaped fixing plate is arranged on the upper surface of the base through the mounting groove. Further, the T-shaped fixing plate is in interference fit with a mounting groove on the upper surface of the base. Further, the adhesion layer is PIND double faced adhesive tape, and the lower surface of the PIND double faced adhesive tape is adhered in the positioning groove. Further, a plurality of counter bores are formed in the upper surface of the base, and the counter bores are matched with bolts to fix the base on the workbench. Compared with the prior art, the utility model has the beneficial effects that: 1. according to the anti-scratch aluminum wire bonding clamp, the T-shaped fixing plate is arranged, the tube shell is fixed on the top of the T-shaped fixing plate through the adhesive layer, the pins of the tube shell cannot be directly contacted with the T-shaped fixing plate, the risk of damage or deformation of the tube shell pins in the tube shell fixing process can be avoided, meanwhile, the plurality of uniformly distributed strip-shaped blocks are arranged on the top of the T-shaped fixing plate to form the plurality of positioning grooves, so that the tube shell placed on the T-shaped fixing plate can be conveniently fixed, bonding efficiency can be improved, and the consistency of bonding technology can be improved. 2. According to the anti-scratch aluminum wire bonding clamp, the PIND double faced adhesive tape is used for fixing the pipe shell in the positioning groove, so that the stability of the installation of the pipe shell can be ensured, and the pipe shell can be protected.
