Based on what you�ve said, comments are: * There is no reason not to expect a trace of Zn in your 85/15 Sn/Pb solderability protection, but Sn/Cu IMC are more prevalent than Zn. * Intermetallic growth and oxidation are very different materials proper

Never try to convince an exec. staff to change manning policies using efficiency, it's a losing cause. Look at your audience, they probably all have MBA's which means they only look at the dollars and cents. To them those aren't production machines o
