How to registrate holes on photosensitive film?

Multilayer PCB image process needs several photosensitive film. From our 4MCPCB experience, we should make one film per PCB layer at least. Even some of the special multilayer PCB have a similar layer circuit, also require separate the image phontosentive film. This point may confuse by most green PCB designers. The importance of aligning photosensitive […]
