Here are links to the web sites for three instruments specifcally designed to monitor wave solder process. Some have SPC logging capabilities: http://www.ecd.com/emfg/instruments/waverider/ http://www.swpc.co.il/wso.htm http://www.solderstar.com/w

Sorry to nitpick, but counting and responding to the number of defects isn't process control. It's done all the time, but it doesn't really fit the definition and that's what I think DB is trying to investigate.

HHmmmm!! looks like i'm getting it way wrong by wanting to chart the quality of product coming from my wave solder machine. could some of you let me know whats the best way to monitor quality on this process.

Thanks to all for the input. It has helped change our standard SPC program around. (To davef: Dad handled most of it, but Vegas got the rest)

We are looking to have SMD components taped and reeled in Brazil. Are their any suppliers in Brazil? cl@latrex.com.br

Tg is just a way to say when the board goes limp... or a quick way to rank laminates... who cares. For lead free you want to look at Td, Decomposition Temperatures. ( Temp at which the material weight changes by 5% )

=330*C is good advice. Search the fine SMTnet Archives for earlier discussions on Td, like http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=32430

I agree A UPS needs electrecity to work so it is definatly not exempt, and im sure it dosent fall into the other catagary either.

Air Academy Associates has a nice SPC package that has the PFMEA calculations built in to it. It also does Cp/Cpk/regression analysis, MSA, et al.You can combine it with a reaally user friendly DOE software for about $250. Both use Excel. Brian
