Homebrew PCBs

I've also had better results wiht with the glossy advertising (Sunday
newspaper inserts)  than with the Staples inkjet paper. My favorite is the
SEARS insert.

I usually first print the -pcb artwork on regular paper, then using laser
labels, tape a piece of the SEARS ad to cover the printed area. The regular
paper acts as a carrier and feeds through the laser printer neatly.

After removing the paper by soaking, I "flash fuse" the toner, by heating it
with a hair dryer, keeping the hair dryer very close 1/8" or 2mm from the
toner.

The flash fusing seems to help the adhesion and evenness of the toner and
makes it more durable.

TANSTAAFL!
