Tin whiskers: mitigation by the application of silica-loaded silicone conformal coating

Abstract

This poster summarises results of a recent study aimed to increase the reliability of miniature high density electronic assemblies for spacecraft application. It illustrates a means to mitigate against tin whiskers growths by the application of a silicone-based conformal coating containing a high loading of micron-sized silicon particles. The tested coating (MAPSIL 213 - SiO2) seems adequate when applied by brush to a thickness of >50 µm. Scratches, bubbles and edge thinning must be absent in order for this coating to be effective.
