Which companies would you consider for protective coatings, (conformal coating) and other levels of protection? I am taking a fresh look at alternatives. Know any good tests for testing compatability of coating with flux - aqueous or no clean? SMT

we are worried about the coating not being able to cover underneath the BGA. If the coat is excessive then it would cause CTE issues. Also if anybody has data on 85/85, 1000 hrs after conformal coating of BGA, would appreciate if you guys can share

I have found that Edding do an aerospace marker, which is water based and does not run with the conformal coating. However, this washes off prior to the coating so it is not much use. Looks like we are just going to have to put some clear tape over

inspect => conformal coat ... and standards are aligned with that philosophy. I can imagine doing a good job inspecting assembly after being coated with particular coating thickness, optical properties, lighting conditions. Ultra-thins are so thin

Does anybody run conformal coating process using UV cure varnish? We have a long experience on solvented urethane coating material but switching to solventless is unknown for us. Could you recommand vendors for UV curing oven? Thanks

Could be as simple as a pail full of UR coating and some wire hangars! Conformal coating is brushed on, sprayed on, and parts are dipped too, not to mention the wonderful vacuum process that is paralene. Gotta have a little more info as to your a

We are having a problem with inspection markings on our boards running when conformal coating is applied We have tried standard permanant markers, and also paint markers, but both run when the coating is applied. There must be someone out there who

Does anyone have a novel idea on how to protect the flex area during conformal spray coating? Currently using Humiseal T30 on the flex but it has to be removed very carefully to insure coating stays intact on the board.

You can inspect joints using an X-ray machine and we use a sand-blaster type machine which blasts (Starch) to remove the conformal coating. (Carbo Blast). However; the inspection should be done prior to Coating, as we all know some jobs are rushed t

Never heard of such a thing. Are you sure the coating isn't just making the solder balls more prominent? Where are the "new" solder balls appearing after coating?
