Hey guys, I have had a good run with toner transfer but the more I get into these small packages, the more failures I am getting. The surface mount chips (100 pin qfp) are just too demanding. I have tried using that dry-film etch resist that you buy on a roll, apply it to the board with a laminator and have had mixed results. Today it took me all of 7 hours to make a small board that is only 60 MM X 60 MM. I am wondering what it a more reliable method to try next. Chris

Need better reliability than I am getting with toner transfer - what's next?
