I worked at a place where a customer complained that the resistance of some components was lowered. It was found to be flux entrapped from the wave solder process. The tube of epoxy, didn't have a date of manufacture, shelf life, or use by date on

Haaaa!!!! Yes, we�ve seen things like that. We found that a high input impedance amplifier worked fine in a room with a controlled environment and worked poorly in the sweat-shop portion of our plant. We were using good ol� WS609, straight water w
