| scott. | I appreciate your sincere answer. | would tell me the hint about printer if i's possible | To tune our smt process we have to know what is the major X's | for defect. To know major X's with DOE we need a good measurement equipment.

Did you try Techspray Wondermask W? It is water soluble and can probably be transferred from the bottle to an EFD type syringe for dispensing (we use the P and the PL that way). As far as if it will swell through the reflow, I don't know. We don't us
