I started out by putting on rubber gloves. I cleaned my board with
sandpaper but it was kinda rough. Need to use a finer grade next
time. and a final cleaning with aolchol.

I set the iron on high. I taped my board to the paper with scotch
tape and placed a paper towel on it, folded in half. I pressed as
hard as I could and moved it around for 4 minutes and WOW!! The white
specks are pieces of the paper.

(see figure 1)

I put it in the etchent for 15 to 20 minutes or so, no heating or
bubbles, stirring every 30 seconds. and washed with water for 1
minute after all the copper was gone.

(see figure 2)

I had to use the sand paper again to get off the toner being carefull
not to sand too much and POW! There it was...

(see figure 3)

I will get the model of the laserjet printer and the paper later. My
friend did it for me. It looked like the lines spread a little during
the ironing. I will have to wait until I get to work to measure the
line widths. My prints look like 10 mil and my board looks like 15 to
20 mil. I still have to do electrical checks but it looks like it
will pass.
