Thanks I already zeroed in on Berquist hiflow 100, app is to coat ceramic for isolating power
devices.
concerns now are do we screen print or transfer print or what? What sort of screen to use, will
it stay stuck in frame if constantly heated to keep berquist molten and so on. Trying to
anticipate problem areas, volume is in several 10ks a run range, so opportunity to mass produce
rejects is good.
