Photoresist is the simplest and easiest method
2003-10-27 by nedtron@earthlink.net
Greetings, I fully agree. The newer generation of pre-sensitized PCBs are vastly improved not requiring special exposure lamps and use less concentrated solutions of developer. As an example, DATAK's Premier series may be exposed with a ordinary 100 watt lamp bulb and use a 10 to 1 developer concentrate. The DATAK's Premier series are actually manufactured by Ever-Muse of Taiwan. The exposed areas of the pre-sensitized layer slightly change color after exposure allowing inspection and adjustment of the exposure results prior to developing. I get very repeatable results without any touch up, failures, wasted material or wasted labor and using minimal equipment. Fabricating PCBs with 0402 SMT packages, SOICs and fine pitch ICs is routine, repeatable and requires no special attention.

From: "zohar_golan" <zohargolan@...> Subject: Photoresist is the simplest ans easiest method Hi all, throught the years, I've tried all the methods of homemade PCB and the best and simple way is to use the precoated PCBs. I was really amazed by the results of this technic. All of the laser transfer is really a waste of time and effort when the photoresiste is so simple and clean. I didnt even use any special lamp but just a regular 100w table lamp. Zohar
