Read articleDry film photoresist is a photosensitive film used to transfer a pattern during PCB fabrication. Its job is temporary: it protects selected areas during a subsequent operation, then is removed at the appropriate stage. Understanding that role helps a designer distinguish the manufacturing image from the finished copper and from permanent solder mask. What the […]
