TW0412-ENVIRON: Tin Whisker Inorganic Coatings Evaluation (TWICE)
This multimedia presentation was given at the IPC Tin Whisker Conference, April 2012, by David Hillman, metallurgical engineer in the Advanced Operations Engineering Department of Rockwell Collins. The author describes a program funded by the Strategic Environmental Research and Development Program (SERDP) to evaluate various conformal coatings to mitigate tin whisker growth. He also introduces an inorganic coating, Alkali Silicate Glass (ASG). He subjects the coatings to temperature/humidity and thermal cycling to evaluate their applicability to long life, high reliability products.He explains the goals of coatings and questions what they can do beyond just capturing and containing whiskers.
This presentation includes the synchronized slides and audio from the original presentation. 22 minutes. Released 2012.
