Cleaning before Conformal Coating

Electronics Forum | Mon Sep 12 14:38:56 EDT 2005 | patrickbruneel

Amol, Your problem is already very isolated only one part has the problem (the part that is hand soldered) Manual cleaning is very difficult. Why are you not considering a no-clean cored solder to solder the one part and skip the manual cleaning. Do

There's a ton of em'. We used the one from Paul N. Gardner Company, part # WF-CCD. They cost 0.95 each, so if someone decides the gage looks better in their garage, it's not that big of a deal. We set up a program that puts down 4 stokes on a test

I agree with Dave 100%, ATC will expose the board and components weaknesses and potential design problems and/or the need for conformal coating. The life span can only be predicted and/or extended by well-documented field failure analyses history and

I actually bought this tape directly from a disrupter of Saint-Gobain series M797. It was placed on 6" x 9" sheets to have unique conformal coating masking cut outs made. Took some effort to get the process worked out but all is well now.

No-Clean Solder

We are in the early stages of converting al of our customers to No-Clean solder. I expect some customers to have no objections, others I am sure will be concerned about the "residue." I know that chemistries have improved greatly and if the process i

Conformal Coat Thickness

We have used many ways of measuring but all are either messy, inconsistent or time consuming. We have done wet, glass slide dry, etc. We are currently using a kapton tape dot system. Spray the board, remove the dot and measure it, subtract the thick

Bubbles in Conformal Coating

Humiseal recommends a 1 to 1 mix ratio of 1B31 and Thinner 521. I have for that I need to thin my ratio more to get humiseal to spray correctly in our PVA650. Also I am using Humiseal 1B73 but the tech data sheets say the same for spraying. Try thinn
