Research on Process of Laser Seal Welding Technology for Microwave Module

Because of the importance of the radar and the high reliable and sealed requirements of microwave modules, the study of sealing the microwave module is urgently needed.The aluminum alloy is used as the shell material of the microwave module, and the processing of laser seal welding technology applied to microwave modules is analyzed. The result shows that the good welding quality without any defects like pores or cracks can be achieved with the parameters recommended. Besides, the air leak rate is about 1×10-9 Pa·m3/s and can meet the standards of GJB 548 B. The result has some positive guiding significance for similar products.
