I use an old version of Tango PCB to generate the artwork and print on the paper with a good laser printer. I usually panelize the artwork if it's small to fill the whole 8 1/2 x 11 sheet. I then bond the transfer paper to the copper clad board using a cheap laminator (I have also used an iron with excellent results). When you are done, you pop the board into some water which will release the paper. What you have left are nice toner traces on your copper board. Now etch. The whole process takes me about an hour. The TTS paper isn't real cheap but works great. You can order it from Digikey. The only secret I found to increase the quality of the transfer is to go over the board real well with a "scotchbrite" pad or equivelent (not steel wool). This roughens up the surface just enough for the toner to bond really well. A great system... I have yet to find an easier way. Bob PS there is a link to Dynaart's web page that has the whole process on Don Lancaster's website: http://www.tinaja.com Jim Fong wrote: > > In article <345E3065.4680@concentric.net>, whims@concentric.net says... > > > >Hello all, > > > >I am trying to find a technique to transfer a circuit board layout > >printed by my laser printer onto copper clad.
