Thanks for all your comments. >IIRC you're using the toner print and press method. Always on >the look out for info. What printer, paper and etchant ? Yes, I'm using the toner transfer method. This is a blog post I wrote showing the steps: http://www.roboticsguy.com/tutorials/printed-circuit-boards/making-pcbs-the= -toner-transfer-method .. I'm using Graytex 32lb high gloss paper, printing with an old HP LaserJet 4MP, and using a laminator to heat up the board. I think the laminator makes a big difference, it works tremendously better then a clothes iron. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
