I think it is useful just to see where varnish should not be (eg connection parts). it is necessary to use another method to measure the thickness.

uV light inspection indicates the "completeness" of coverage, but provides no measurement of coating thickness.

Tape test to check adhesion and multiple point thickness test - each board has 5 points per side documented for thickness testing & we measure pre & post coating thickness with an electronic meter. Also temp & humidty are also logged, and alarms go o

Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho

You aren't going to post our stuff on your "Hey, I'm the wizard site", are you? Board fab, Pad coatings, OSP 1 OSPs: Imidazole (Via Systems) is good. Entek (Enthone) works, but requires strict thickness control in fab. 2 Enthone CU56 allows one t

We consider "IR-reflow soldering profile" to be the supplier's recommended reflow thermal profile that a component temination 'sees' for proper soldering, regardless of the method used to reach that temperature. When you say, "We have a lot of defec
