BAR strip test carrier

Abstract

The invention provides a BAR strip test carrier which comprises a BAR strip carrier base, BAR strip pressing block fixing blocks and BAR strip locking pieces, and a groove is formed in the middle of the BAR strip carrier base; the number of the BAR strip pressing block fixing blocks is two, and a cross beam is fixedly connected between the two BAR strip pressing block fixing blocks; a probe with an elastically telescopic lower end is fixed on the cross beam, and an engineering plastic pressing block is fixed at the lower end of the probe; the number of the BAR strip locking pieces is two, and one BAR strip locking piece is arranged between each BAR strip pressing block fixing block and the BAR strip carrier base and used for enabling the BAR strip pressing block fixing blocks to be pressed downwards, so that the BAR strips are pressed on the BAR strip carrier base through the engineering plastic pressing blocks. Accurate positioning and stable clamping of the BAR strips can be achieved, the BAR strips cannot slide and collide in the transferring process, the clamping force can be controlled, and feeding and discharging are facilitated.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a BAR test carrier. Background technique [0002] In the chip production of optical communication, the wafer will not be directly cut into individual chips, but will be cut into strips with a number of N (N≥2), which we call BAR (multiple laser generator combination). And this BAR needs to test the parameters of the chip in it. This test process needs to be carried out on the test equipment after positioning the BAR. [0003] The current conventional BAR positioning method is to place the BAR on the tray through a carrier or a fixture, then place the BAR on a platform with vacuum suction through tweezers or a vacuum pen, and then manually move the BAR to the reference position through tweezers, etc. (Ensure that the light emitting direction is vertical to the detection device) [0004] Conventional carriers are horizontal pallets or pallets with limit slots: [0...

Problems solved by technology

However, there is also the problem of inaccurate positioning when loading materials, and there is a disadvantage that it is difficult to place them in an accurate position.
