High precision vacuum exposure unit especially designed for double sided contact exposure of presensitized base materials such as tampon printing clichés, PCBs, front-panels, daylight films and other UV sensitive coatings.
This line is to form the patterns on the panels by chemical treatment, whose configuration is Developing + Etching + Stripping. Developing and Etching module with our rotary spray system are readily achievable high etching factor to a fine pattern. It can be used a chemical, CuCl2 and FeCl2.\
