REGISTRATION SYSTEM FOR PHOTOTOOLS

摘要

There is herein described a method and apparatus for positioning a phototool. More particularly, there is described a method and apparatus for accurately positioning a phototool capable of photoimaging a substrate (e.g. a web) covered with a wet curable photopolymer wherein the phototool creates an imaged substrate which is used to form images suitable for forming electrical circuits such as for printed circuit boards (PCBs), flat panel displays and flexible circuits.
