Carroll, You're right. Damn, I forgot all about this super process of the past. Another trip down a lane long ago destroyed. Kinda like route 66. Used the Hydro a couple of times and kicked out of house. Bad, bad process. But along came hole plugging as the advent of solder mask over bare copper and look at us now in control of all processes available. Wonder why so many questions? Whoha hoss!
