thanks for your reply sir, for conformal coating Humiseal 1B31, what are the preferable staking materials? please suggest us..

Can we apply staking after conformal coating.

I would suggest Zymet CN-1703 for staking of the components using this coating material we use it very extensively with Humiseal 1B31, if you would like; I would be happy to coat a couple of your samples for your evaluation.

We have 2 PVA2400 4 axis selective spray machines that we use to spray Humiseal 1B31 and 1A33. They take a bit of programming to get right, though this is easy to do, but do the job OK. Another to consider if you need the 4 axis of movement would b

What masking tape can people recommend for masking the board when conformal coating. I am using a PVA autocoat machine and humiseal 1B31. Current tape, is leaving residue on board when used to hold link wires down whilst glue cures and also when used

My company recently aquired an asymtek coating machine and I have been using Humiseal 1B31, an acrylic coating, in it to coat all the boards given to me. They have now come to me and asked if it is possible to run Humiseal 1A33, a urethane coating, t

Does anyone have any input on the need to bake out an assembly prior to the conformal coat process? I understand baking out components/pwb's prior to processing through the reflow or wave solder process if the material shows excess moisture absorbtio
