Abstract

The invention provides a method and device for testing a COB optical module before Lens coupling, the COB optical module before Lens coupling is hereinafter referred to as a COB optical module, and the method for testing the COB optical module before Lens coupling comprises the steps: obtaining a test instruction; judging whether a COB optical module is inserted into the burn-in board or not; if the COB optical modules are inserted into the burn-in board, the optical detector is controlled to detect the multiple COB optical modules on the burn-in board, target detection results of the multiple COB optical modules are obtained, and if the target detection results are abnormal or normal, and if the detection results are normal, the COB optical modules enter the subsequent process. According to the invention, the COB optical module is detected before the Lens coupling process is carried out on the COB optical module, the abnormal COB optical module is identified, and the manufacturing cost of the COB optical module can be reduced.

Description

technical field [0001] This application mainly relates to the technical field of optical module testing, in particular to a method and device for testing COB optical modules before Lens coupling. Background technique [0002] The packaging process of optical modules includes TO, BOX, COB (chip on board), etc. The process usually used for high-speed optical modules is COB. The current COB optical module production process using the COB process is: 1) patch; 2) wire bonding; 3) plasma cleaning; 4) Lens coupling; 5) aging; 6) structural assembly; 7) firmware upgrade; 8) testing . Lens coupling is to couple and paste a Lens lens on the PCBA of the COB optical module. At this stage, the Lens lens is placed on the bonding surface, glue is dispensed, and the coupling position is adjusted. After the coupling is completed, it is cured by a UV point light source. . The Lens coupling process is extremely important in the existing production process, but the COB optical module has no...
