Novel Whisker Mitigating Composite Conformal Coat Assessment

An electronic assembly is created by integrating thousands of parts from multiple suppliers utilizing a host of circuit card manufacturing processes. With the lead elimination from electronics resulting from the European Union Reduction of Hazardous Substances (RoHS) legislation, many of the heritage aerospace and defense commercial off the shelf (COTS) solder materials with tin–lead have become obsolete. Most notably there has been an increasing cost and schedule pressure to use commercially available pure tin part finishes and lead–free solders in aerospace and defense electronic systems.
