Study on the Matching Between Potting Process and Product Structure Design

In the design of highly reliable microcircuit module, the potting process was adopted usually in the packaging structure to meet the requirements of product in mechanical shocking and vibrating, harsh environment, heat exchanging, insulation, etc. A typical stress failure case of certain potting module was analyzed. A method was proposed to investigate the matching and suitability between the potting process and product structure design, and it was verified by simulation and test. This method provided a theoretical guidance and technical support for the subsequent study on the matching between the potting process and the product structure.
