Does anybody knows any outside service for SIR testing. I am being question if my cleaning process is good enough and I don't have any ways of proofing it.

Chiakl Ion Chromatography has been perfectly described by Dave, but here are a couple of extra considerations: Ion Chromatography will tell you precisely what is present on the surface of your board/assembly but it will not tell you whether it will b
