To all, We are trying to cost reduce part of our through hole assembly. We build high voltage power supplies and they don't lend themselves to SMT. The boards have the standard LPI solder mask, but we need to mask some component holes for components that are installed after wave solder. Currently we apply ChemaskŪ Peelable solder mask by hand from an 8 fluid ounce bottle. I know there are ways of applying a solder mask using a silkscreen. What equipment is needed? What mask material should I use? What support equipment do I need? Did I leave anything out? Thanks in advance for your input.
