Grace Electronic Materials has announced a new UV curable etch resist. Voltacure SR 338 is a high thixotropy UV curing screen print ink which resists acid or alkaline etch processes (or plating) and strips into solution at pH 11–14 at low temperatures. The ink has good adhesion and flexibility and printed boards can be stacked immediately after cure. Benefits include: fast fine line printing; easy cure; problem‐free stacking; adhesion and flexibility for flex circuits; good etch resistance for thick (2 oz + ) copper; acid or alkaline etching; easy stripping into solution at low temperatures.
