I use a picture dry mount press, followed by an iron.
The dry mount press prevents any sliding of the paper on the PC board
during the initial heating, but is not really hot enough to do the
entire job. I then remove the board from the hot press and use an iron
on linen setting for 2 minutes to finish it. The iron provides more
heat to ensure large ground plane areas transfer without holes. YOu
know it's done when the waste sheet covering picture paper just
slightly starts getting brown.
The best paper by far for me is the "Staples Picture Paper, 30 sheets
for 10. item no. 471861 (details here) -
http://www.fullnet.com/u/tomg/gooteepc.htmI let it soak for 5 mins then use a tooth brush to get it off. This is
by far the best technique for toner transfer I've used so far. I tried
label paper, etc. and this particular photo paper combined with
soaking removal works best for me.
