I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.

We don't have one of those cool air compressed syringes to dispense adhesive. We have to do it by hand. My question is does anyone have any suggestions on syringe size, needle size etc... for successful deposition of SMT adhesive? I know you can go s

I witnessed this at our sister company. It seems to be their standard process. It is not my place to interfere with their processes. I was just curious if there was any chance of brittle solder joints or other defects that might be caused from the WS

SMD Inspection and Touch-up

Electronics Forum | Fri Jul 23 10:47:31 EDT 1999 | Mark D. Milward

There is a practise within the industry of an Inspector inspecting a board, and that same Inspector performing touch-up. My opinion is that the Inspection and Touch-up operations should be separate functions whereby the Inspector is not performing th

Touch-up and Inspection Process

Electronics Forum | Thu Mar 03 09:04:26 EST 2005 | russ

Been following this thread and have a question, Why do "touch-up" people follow different criteria than "Q.C." people. It sounds like the root of the problem is not addressed but bandaids are being put into place. We have no "Q.C." department and
