Failure Analysis of Microwave Module by ESD Effect

In this paper, it is confirmed that the electrostatic discharge is the cause of failure of the microwave module. The confirmation is based on a series of failure analysis, simulation tests as well as theoretical analysis on the failure case of a microwave module. In order to ensure the microwave performance, no electrostatic protection circuit was designed during the production and application of microwave modules, thus making the electrostatic discharge one of the main reasons for microwave module failure. In this paper, the characteristics of the harm of ESD toward microwave module are analyzed and an improved method is proposed through verification test. That is to add electrostatic protection measures around the circuit. This case provides reference and basis for prevention and control of electrostatic discharge hazards during production and application of microwave modules in the future.
