Hello, I've been doing some PCBs by "hand" for a year or so. Now I would like to use SMD and superficial IC, and I need more accuracy and posibility of making several boards. I tried 4 or 5 times with tonner transfer. Results are not good. I use magazine paper, I tried 2 o 3 of them. Glossy. I print using a LaserJet 6. I iron at high temp, for 10 minutes or even more. I wash in warm water, and leave there a few minutes more. Then I peel the paper (it takes time and effort, sometimes I just damged a track). The pattern is firmly transfered, and it actually takes a lot of effort to remove from the copper using disolvent. BUt the pattern is heavily damaged. Many track cutted, pads missing,... I manage to get some better, but I need very good acuracy for SMD, can't just finish by hand... I don't know what more I can do... I'm thinking on going into photographic methods. I was thinking on getting photosensitive boards, print a mask, and expose it to UV light. Then, as far as I'm concerned, I will have to put in developer, and then etch. Can you guys help me out? any advice?? Any ideas?? Thank you so much
