Abstract

The invention discloses a self-adjusting fixture for laser chips, which includes a positioning groove and a bar-shaped groove provided on the top surface of a base. The positioning groove communicates with the bar-shaped groove and is used for placing chips. The front end of the positioning plate is provided with a right-angle positioning notch, the positioning groove has a positioning right angle, the two sides of the right-angle positioning notch are in extrusion contact with the adjacent two sides of the chip, and the two sides of the positioning right angle are in contact with the other two sides of the chip; An elastic piece is also installed in the strip groove, and this elastic piece is connected with the rear end of the positioning plate, and when the elastic piece is in a relaxed state, the front end of the positioning plate is separated from the chip; the base is covered with a limiting plate, so that The positioning plate is located between the limiting plate and the base. The invention can not only reduce the difficulty of processing and testing, improve the processing efficiency and precision, but also enable the chip to be placed in the positioning groove in a horizontal state, avoiding the adverse effects of chip warping on the processing accuracy and clamping stability.

Description

technical field [0001] The invention relates to a self-adjusting clamp for laser chips, belonging to the technical field of chips. Background technique [0002] When making a laser chip, not only the chip body needs to be mounted on the ceramic substrate, but also the chip body and the ceramic substrate need to be connected by gold wires, and the chip needs to be photoelectrically tested; therefore, in order to achieve efficient chip production, it is necessary to Chips are fixed in fixtures, and are processed and tested in batches using equipment such as placement, gold wire bonding, etc. [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 applied to the laser, in the actual operation process, not only the vacuum pump The vacuum hole is easy to block, and during the placement, processing and transfer of the chip in dif...
