We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo

You'd more than likely have repairability issues with the Acrylic based one. The acrylic-based finish is alot harder and more brittle versus the silicone. Some of the new silicones, you can just "peel" with your fingernail, while still getting reli

We are producing boards with Alpha 591S RMA No-Clean paste and are coating after SMC with Dow silicone ( toluene solvent based) conformal coating. We have experienced several failures due to soft shorts ( electrochemical migration?) We have also obse

Hello to all out there, We're considering CC process,and would like to know some defferences between SSC3 of Electrolube and Humiseal 1B73, yes,I know that SSC3 is silicone one,and Humiseal 1B73 is solvent based acrylic as well as other basic propert

Hi, Currently we are facing bubble formation in conformal coatings in the pcba. Have varied various specs of the conformal coating machine, even during manual application also having the same issue. the material used is silicone conformal coating. N

Thanks for the info Sarason. The UVCL is a Urethane. Did not want that hard of finish (for solder rework issues). We like the Acrylic as acetone will remove cured material for solder rework.

We allow no silicone in our shop, because they ruin solderability.
