Self-adaptive fixture for laser chip

Abstract

The invention discloses a self-adaptive fixture for a laser chip. The self-adaptive fixture comprises a base, an elastic piece installed on the base, and a pressing plate located above the elastic piece, and the base is provided with a locating slot for the chip to be embedded; the elastic piece comprises a connecting part, a deformation part and a locating part, and the end of the locating part of the elastic piece is provided with a right-angle locating notch; the pressing plate is in extrusion contact with the deformation part of the elastic piece; the pressing plate comprises a main body part and a plurality of elastic trim strip parts corresponding to the elastic piece, and the elastic trim strip parts are connected with the main body part, and are in extrusion contact with the elastic piece; and a strip-shaped pressing block is installed on the top surface of the main body part, and connected with the base. According to the self-adaptive fixture, not only can the processing efficiency of the chip be improved, but also the self-adaptive fixture can be adaptive to the dimensional tolerance of chips of the same batch; and the processing and test precision is improved.

Description

technical field [0001] The invention relates to an adaptive fixture for laser chips, belonging to the technical field of chip processing. Background technique [0002] When making laser chips, not only the chip body needs to be mounted on the porcelain substrate, but also the chip body and the porcelain substrate need to be connected through gold wires, and the chip should be photoelectrically tested; therefore, in order to achieve efficient chip production, it is necessary to Chips are fixed in fixtures and processed in batches using placement and gold wire bonding equipment. [0003] At present, there is a chip fixing fixture on the market, which can temporarily fix the chip through the chip groove and the vacuum hole in the chip groove. However, due to the small size of the chip used in the laser, in the actual operation process, not only Vacuum holes are easy to block, and during placement, processing, and transfer of chips to different machines, the chips are prone to ...

Problems solved by technology

[0003] At present, there is a chip fixing fixture on the market, which can temporarily fix the chip through the chip groove and the vacuum hole in the chip groove. However, due to the small size of the chip used in the laser, in the actual operation process, not only The vacuum hole is easy to block, and the chip is easy to loosen and deviate from the initial position during the placement, processing and transfer process of different machines, and even bounce off the chip slot, which increases the difficulty of processing and affects its processing efficiency
