Any processes that I need to be aware of that differs from standard FR4 during reflow and wave soldering? I've read one of the problems is the thermal expansion of teflon is quite different from copper. I've also seen a "blurb" where teflon absor

Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums

This is a good idea. Heck, you could fill the bags with sand, if you wanted. Like anything else in the shop, bean bags require attention and maintenance. If you don't, eventually the seams on the bags loosen / break and you have to do a "clean-u
