Thanks. Yes, this is a interesting topic, and one that keeps our component engineers busy these days. I'm familiar with the data you referenced. Is there a "easy" method (test method) to use at incoming inspection to verify a termination is "matte

IPC Plating Committee is presently working on a specification for immersion tin [IPC-4554 Specification for Immersion Tin Plating for Printed Circuit Boards] as a solderable surface finish. Immersion tin is normally deposited at 30 to 60 microinches.
