I have an application that requires soldering pieces of metal (copper plate and copper fins to make a heatsink). Each piece is about 1 lb. I cannot test it in our reflow oven (5 zone) since the piece is about 3" in height. Has anyone attempted to

I would say it depends on the process requirements for the board and the reliability requirements as has already been mentioned. If you do two-sided reflow you might allow for fewer rework attempts, for example. If it's a medical device you might on

First, no one knows very much about the relaibility of Pb-free assemblies, much less Pb-free solder with Pb-bearing components. Second, we do know that Pb-free components work with PB-bearing solder. Third, based on comparison laboratory testing,
