Do you buy in the PCB's from a manufacturer? If so, they may well offer such a service for you. We get quite a few different boards that come with either Kapton tape, or liquid masking already applied.

What's this 'metalic coating on both sides'? Is that like a 'two-sided board'? I expect that your 200�F is the primary side temperature just prior to entering the wave. If not, you need more juice [depending on your flux and all that]. [Some mode
