Hi Patrick,
I use Eagle Lite. That version will do small double sided boards
free. Download from
http://www.eaglesoft.de/freewarePrep your boards the normal way
Put board on a block of wood covered with a doubled paper towel
Set iron to cotton/wool setting with no steam (you need to
experiment with correct temp.
Place board on board, align artwork (trimmed to slightly larger than
board), cover with another doubled paper towel (be careful not to
let transparency slip)
Apply iron for 20-30 seconds. Gently lift from one corner making
sure to hold down transparency while lifting paper towel.
Transparency will usually stick but will stop after transparency
gets it's fill of paper fibers.
Iron and check progress every 30 seconds or so to see when toner is
melting. You need to get it all melted, but not so much that it
smears badly. Watch for traces that are starting to spread and
don't let pad holes close completely.
When you think things are melted well enough, remove the board from
the block of wood and set it aside to cool.
Start your next transfer if you have more.
When the first board has cooled to the touch, but is still warm,
peel the trasparency from the board; starting at one corner. If
little or no toner stays on the transparency, you're done.
If a lot of toner stays on the transparency, stop peeling as soon as
you notice that. Iron more and try again.
Once the transparency has been removed, you may notice some residue
from the transparency. Clean this off with soap, water, and a
toothbrush. You don't need to do this under running water. Wet the
board, apply some soap (I use liquid hand soap), scrub the board
thoroughly (shouldn't have any problems with toner being removed),
rinse board, blot dry and store in plastic bag until ready to etch.
That's it.
I cut and paste my design and array (panelize) it so it fills as
much of the transparency as possible. I leave enough empty space
for a 1" boarder around the perimeter and 0.3 inches or so between
patterns. Keep your fingers off the toner side and store them where
they won't collect dust.
Make sure there's no dust on the board or transparency when you
start transfering.
Regards,
Dennis
