Hello colleagues, Question. Who ever done 4 mil (100uM) electro conductive epoxy dispensing? is it even possible? I did 6 mil but very unstable results... Now I need 4 mil for an application.

This has been a tough one to date. Any ideas will help. Problem definition � random QFP144 part not soldering all leads. Percentage fallout is about 1-5% of boards. Usually leads, one or more, on trailing side to the direction of travel does not wet
