In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

I'm using urethane conformal coat and have fisheyes and dewetting after coating even though the PWAs have been through the wash cycle twice. I'm looking at using Ionox 13302 in an ultrasonic cleaner as a short term solution until root cause can be identified and resolved. What are the pros and cons of this solvent? Is there a chance of component damage as there are sone potentiometers on board? Will the labels, inspection stamp impressions, or other markings be removed? What temp does the rinse water have to be and for how long?

I think you are a genuis. The idea in your post is quite helpful and lights me. I have been puzzled for a long time in my new project.
