TECHNIKS "PRESS & PEEL" PC BOARD KIT

I have made printed circuit boards for years, using Datak positive coated circuit board material and inkjet or laser printer transparencies. I use a contact frame and the full sun to expose the coated boards. I have trouble getting enough contrast (dark enough blacks) to get un-etched traces with any exposure and development using
Datak developer. I have used both ferric chloride and hydrochloric acid / hydrogen peroxide etchants. The ferric chloride requires more care in handling and disposal, but I think the etching is more controllable. With toner transfer and glossy cheap paper I have had multiple failures due to either paper jams in the laser printer, or great difficulty in removing the paper after transfer. With the Press and Peel, the sheet just falls off in cold water,leaving a solid transfer on the copper. I use a small iron designed for applying wood laminates to plywood edges (from Woodworkers Supply) to iron the toner to the copper. Just print the artwork on regular paper, and the cut a piece of Press and Peel to cover the printed artwork, Tape it over the artwork and print again in the same orientation. Cut the paper with the Press and Peel still attached and place both onto the copper (the paper will protect the transfer sheet from the iron) I drill 2 small holes in the copper board, to suspend the board in the etchant with fishing line, and etch in a vertical tank. It is easy to lift the board to agitate the etchant and inspect the progress of etching with the fishing line.

Can't get it to work after several tries. Takes a long time for the ink to dry after printing. Using HP deskjet. Going back to silkscreen.

The first time I didn't iron long enough, but the second time it worked great. I used the sponge method.

this transfer film is worth the money it works awesome and i just follow the instructions.
and i suggest u don't waste time using the "put pcb in echant and wait" method, instead take a cellulose sponge and saturate it with ferric chloride then rub the pcb then the copper will disapear after +-5 rubs. it takes 30 sec to etch!

I never clean the PCB board before ironing and it always sticks just fine. I think the real trick is iron at high temp. and lots of pressure - i.e. press down hard with the iron and massage into all crevices. Is this 8.75 for one sheet? Editors Note: That is $8.75 per package of 5 if you purchase 2 or more packages.
