Hi Doug, I'm kind of thinking like Jerry in that you could vacuum form a plastic over the top of a board. You may have to scrap a board and drill a bunch of holes in it for the vacuum to work. Drill a populated board, fixture it up in a vacuum form machine, heat up the plastic and form it over and all around the components. Remove the new plastic cover and make another one. You might have to figure out a way to seal it around the edges but it might just work. I've done some things in the past with vacuum forming that were incredibly intricate and accurate. Sounds like a fun project.

It was not molded to the PCB but was molded to a model that had been made of the PCB. In that application they actually glued the cover at the corners to the PCB after it had been screwed down to the enclosure. They said it was for the same reason you give, to keep a stream of water from directly contacting the PCB. I do not know where they had it done but I think getting a good model would be the hardest part.

And Friday seems to be a time for silly questions, so here goes. Have any of you ever seen a product that essentially vacuum forms a plastic film over the surface of an assembly? Not a chemical vapor deposition like Parylene or conformal coat process. For a particular (really odd) application, I want to put a rain guard on the surface of an assembly. Something where I could take a squirt gun and shoot water at the assembly and never have it hit the surface (of the assembly). Don't ask why.
