Hit wax dip of your edge connector. HVLP spray your conformal coating. hot alkaline wash to remove the wash. Followed by de-ionized water. Other techniques using peallable latex. Sarason

Can anyone share some good practices to reduce FOD in the conformal coat area? I am new and trying to get my hands around a serious FOD issue. We get red, black, blue, and white fibers that gets trapped in our conformal coat, causing a lot of scopi

For anyone looking back on this post, I ended up figuring out something that will work for my process. Jack up the atomization pressure on the guns, lower material flow, quicker-lighter coats, less time between coats, and more coats. Smooth, even f

| I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec

Paralene, Paraxylene, or other vacuum deposited coating will require this method to remove the coatings. UR and Acrylics have solvents, as Rob above has mentioned. Plastic bead media and wheat chaff are ones that I know have been used for Paralene

Hi, I am running a circuit board that needs a part to be put on it after cleaning and before conformal coating. the only problem is that after cleaning and hand assembly of the part, there is a thin whitish residue in the ckt board that one can see w

We supply to defense primes, so there's not really any wiggle room on these sort of issues. Thanks for the idea though.

Have you considered Teflon boots over your connectors? 1B31 cleans up quite nicely with IPA. It makes reusable fixture concepts pretty attractive.
