I thought I would share this with everyone since I have noticed a lot
of postings recently about toner transfer problems.

I had a problem a while back getting the toner to stick to my circuit
board when using my laminator. Out of desperation I preheated my board
using a clothes iron. I monitored the temperature with an IR
thermometer until it got to the correct temperature. After getting to
the desired temperature I passed it through the laminator a few more
times. I managed to get a perfect transfer.

I have not made anymore boards since then, but what I plan to try the
next time I make a board is

1. Pass the board through the laminator a few times to tack the toner
to the board. Very useful when doing two sided boards.
2. Put the clothes iron on board to get the temperature up. I do not
plan to apply any pressure other than the weight of the board. Monitor
temperature with an IR thermometer.
3. Pass the board through the laminator once or twice.

I figure at the very least it should save me passes through the
laminator and reduce the wear and tear.
