Hi Cecil, We using conformal coating in our manufacturing area, we did use to use Humiseal, others have been Bectron and Peters. We recentalt switched all lacquering to Peters, since it is lead free and it is a lot friendly than Humiseal. To answer

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef

First, it appears that your solder mask and your coating material appear to be incompatible. Second, IPA leaves a residue that's probably not compatible with your coating material, either. IPC-HDBK-830 - Guidelines for Design, Selection and Applic
