AbstractThe objective of this SBIR Phase II project is to make significant steps toward the commercialization of a tin-whiskers containing thin film coating. Atomic Layer Deposition encapsulating films (ALD-Cap) are flexible ceramic films, with exceptional conformality, adherence and mechanical strength. Developed primarily as a low-cost environmental protection and corrosion barrier, ALD-Cap was successfully used to protect MMIC components used by the Navy, as well as other environmentally sensitive devices and components. Tin whiskers pose major safety, reliability and mission readiness threats to all makers and users of high performance and/or high reliability electronics. In the very near future, most military and other high-reliability electronics will likely require both environmental/corrosion protection and tin-whiskers containment/failure-risk-mitigation. ALD-Cap may provide a crucial solution for both problems. These ceramic coatings are more than 50 times tougher than Parylene, the toughest conformal coating attempted so far. At the same time ALD-Cap coatings are proven to be flexible and crack resistant. Tin whiskers containment coating will be further optimized and commercialized to enable fast-track certification of PCBs and components as whiskers-free.
