As I understand it, though, a 90 sec. 75F wash and a 15 second rinse (plus the lift cycle, another 10 secs., perhaps) at a MAX. of 110F isn't supposed to be nearly enough of a swing to swell that epoxy or expand the foil. According to my contacts at

There are two primary causes of epoxy adhesive bond failure, heat and over exposure to moisture. Ultrasonic cavitation is a only a mechanical "scrubbing" action on a microscopic level. However, if the adhesive bond is week or has small areas of det

When it comes to how much epoxy [aka. "glue"] to dispense to hold a IC or any part with significant mass, on the bottom of a board for wave soldering, is more better? The way I see it, one good dot should be holding such a part on the PCB. If not, th
