For screen printing UV curing (UV curing) insulating ink, PET or ITO film can be printed on the insulating layer to conductive lines printed on the top ITO film can be printed in the dot-type compartment. Main purposes: printed circuit printed on the bridge (CROSSOVER) insulating layer, interlayer printed circuit board copper etching, printed circuit printed dot type compartment. In the high temperature and high humidity under the environment remains very good adhesion, UV radiation will be immediately cured, easy to operate.
