Hi BJ, Everyone's favourite answer...it depends! If the volume if large, masking boots will save you both, time and money in the long run. Custom boots are relatively expensive to buy, but they pay themselves over time by savings on masking tape. ma

Hi Tim, I would speak to your guys at Indium, as I am sure they have a paste developed primarily for Conformally Coated products which should alleviate your problems. John

Beyond just the cosmetic dewets reliability is very flux/coating dependent. Don't forget about any touchup or hand soldered parts after wave as well.

Tim, try and incorporate an inline wash system. We use one with a surfactant and it cleans the "NO CLEAN" fluxes well. If you dont have an inline system, you can manual clean the boards with an surfactant and IPA. You can also do an ionic contamin

We are in the process of validating Silicon 1C55 (thermal cure) conformal coating over Alpha LR725 solder paste. I am looking for anyone who may be using this process, or has been exposed to someone who is doing this process. Our concern is with the

HumiSeal 1C55 is used by several of our customers over NO-clean pastes with success. Have you seen anything to cause concern?
