A similar, but I think easier tecnique, is to print on a special plastic sheet "TEC 200", then transferring it to the copper side of normal PCD by simply laying the sheet upside down on the copper and using heat and a rubber roller to "press it over". A friend of mine is using this technique. You have to print using laser printer or photo copier. In the Nordic Countries and Poland it can be obtained from Elfa, ph +46 08 7353535, artnr 49-516-38. /Morgan O. >Hi, > >I was wondering if anyone has tried (and been successful with) the PCB >trace making method described in the November 1997 Electronics Now article? > A laser printer was used to print the trace onto a piece of paper-backed >flexible copper sheet.
