I am trying to do a "sanity check" on an SMT hourly consulting rates. The work requires expertise in SMT process, IPC inspection guidelines and as well as hand assembly. The work would be performed in China but needs to be performed by an American.

Who performs SPC (Statistical Process Control) in your surface mount or through hole department? The machine operator, an inspector, or a seperate SPC inspector?

From alpha metals lead free alloy impurities bulletin: "Levels greater than 0.025% may start to slow the wetting speed and could affect the hole fill performance. If process performance is OK then levels up to 0.05% are OK."

Why don't you use OEE (or OLE for the whole line) where you will involve downtime (availability), performance and quality rate. We're currently using this metric for our SMT lines, if you need info just let me know.

Thanks, Evtimov. In terms of mechanical drop performance, can we conclude that the higher Ag alloy will have poorer drop shock performance relatively compare to those with lower Ag? The Ag3Sn is a good IMC for welding strength?
