Homebrew PCBs

That's fantastic! I've linked to this message in Links/Toner_Transfer to make it simpler to find in the future.

This is not a fluke...I've had many of those, as well as many failures.

I use a GBC personal laminator, modifed as per the Pulsar website (changed one of the thermostats).  To get the perfect transfer, I also use the 0.032" pcb, purchased from Pulsar, but available many places.  Using this half-thickness board and passing it through the laminator 10 times, 5 in each direction, either x or y.  I then place the (very hot) board/vinyl combo in the freezer for 20 minutes.  At that point, the vinyl peels off, leaving 100% of the toner on the board.  No clay residuals like I have with almost any type paper, other than the Pulsar or Chinese stuff.  Perfect, clean, sharp tracks and pads.
