Abstract

A semiconductor laser COS alloy strength detection device and detection method, the lower end of the indenter can be seen through the eyepiece of the microscope, the position where the COS needs to be peeled off can be accurately found during observation, and the accuracy of the detection result is improved. The position of the fixing bar can be adjusted by the translation mechanism, so that the laser tube seat on the die bar that needs to remove COS is located just below the pressing needle. Use the indenter drive mechanism to drive the indenter down to complete the peeling of the COS on all the laser tube bases on the die strip. After the COS is stripped off, observe whether the silver glue residue on the tube base is void and uniform, so that the alloy can be accurately judged. Whether the strength meets the requirements. The whole device is simple in structure, low in cost, convenient and reliable in operation and inspection, and solves the problem that the force is not easy to control during manual COS rejection. At the same time, in the process of COS rejection, the operator does not directly contact the product, thus avoiding the human factor causing the product pollution problem.

Description

technical field

[0001] The invention relates to the technical field of semiconductor laser packaging, in particular to a semiconductor laser COS alloy strength detection device and a detection method. Background technique

[0002] Due to the advantages of small size, light weight, high electro-optical conversion efficiency, long life and high reliability, semiconductor lasers have gradually replaced the use of gas and solid-state lasers in the fields of communication, medical treatment, display, industrial production and security. is also gradually expanding. The working principle of a semiconductor laser is: through a certain excitation method, a non-equilibrium is realized between the energy band (conduction band and valence band) of the semiconductor substance, or between the energy band of the semiconductor substance and the energy level of the impurity (acceptor or donor) Stimulated emission occurs when a large number of electrons in the state of population inversion r...
