I recently had to make a couple of PIC boards to automate a small water
pumping system for a local fish plant. It's been many a year since I had to
make a pcb without benefit of a company facility.

Several members on the qrp-canada reflector directed me to sites with
information on laser printer transfers. After a bit of experimentation I
found that printing to 720dpi photo quality ink jet paper on the laser
printer set to its maximum dpi setting worked very well. Lower dpi photo
paper may work as well - I didn't have any to try.

One board required a bit of very minor cleaning up with a razor knife
because I didn't get all the paper fibers removed after the toner transfer.

I'm very impressed with this method of small quantity board production.
Sure beats coatings of sensitizer chemicals and UV exposure lights.


PS. For those on here who sent me info re pcb drawing programs - thanks!
I've been playing with them as time permits.
