Morning all. So today I have been tasked with conformally coating a few of our first run PCBs for a new product line. The problem is that they have already had all the larger caps potted with RTV. Are there any problems with spraying the CC over the

If you apply the RTV after coating, what happens to bond strength since you are now bonding to the coating and not the board? Will the caps still survive vibration and shock? I specify applying RTV before coating for this reason. Am I correct? I als

We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

Anyone aware of an acrylic conformal coating that is UV curable?

how does polyurethane used for wood floor coating differ from urethane conformal coatings sold for circuit boards? where can i get uv tracer to put in oil based urethane?

Alternatives are: * DSCC Columbus continues to maintain the QPL for MIL-I-46058C. [Engineering is unlikely to change.] * Use International Electrotechnical Commission Standard, IEC 61086 - Coatings for loaded printed wire boards (conformal coatings)

Many companies use IPC-CC-830B as a replacement for the deactivated MIL-I-46058 conformal coating standard.

We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

Humiseal says, "UV cure – These materials are also more difficult to repair as they are the most chemically resistant and mechanically tough of all conformal coatings. Removal is possible locally by using powder abrasion."
