Printed Circuit Boards for the Masses

Printed Circuit Boards for the Masses

Creating PCB’s at home has always been a hassle. But this procedure is simple. You need some Jet Print brand glossy photo paper.

The basic methods available include manually laying out the traces with trace transfers (not recommended), photoreproduction (specialized, and expensive), or the use of a laser printer using the toner transfer method. This latter has been somewhat hit or miss for me, with variable results, until I did a bit of internet research and discovered an absolutely dynamite paper. All the credit goes to Tom Gootee for finding a paper that really works.

The next step is to produce a positive image of the traces you want, using almost any editor, CAD program, etc. The image must print to the exact scale needed. 

Once the image is created, test-print the traces on a sheet of regular paper. You must use a laser printer; inkjet printers will not work. If it all looks good, load a sheet of the Jet Print into your printer tray, set your printer for darkest image, and print. Here is the image of my traces printed to the Jet Print paper.

Cut out the traces, leaving a bit of paper surrounding the traces as a border. Prepare your copper board by first sanding lightly in a cross-hatched pattern with 400 grit paper. Next, degrease and clean the copper with alcohol or similar. My Jet Printed circuit is shown here next to a small, prepared board.

Borrow an iron from the house boss. Set it on its highest temperature, and allow it to warm up. Tack the paper down on one corner of the board. It will immediately begin to fuse and stick. Continue to iron the paper onto the board. Go ahead and use a bit of pressure. This 2″ sq. board was ironed for about 3 minutes. Use the edge of the iron as well to apply higher pressure in a pattern. You can tell when you’re done because you will actually be able to see the traces through the paper. Something in the heating process causes this phenomenon. Give it another minute for luck, then, drop the fused paper and board into a bowl of hot water. It will immediately bubble and begin to separate from the copper. Don’t rush things, let it soak for a good 10 to 30 minutes. You may need to help the paper separate a bit… it won’t float free on its own. But if you used a good hot iron, you won’t have any trouble with trace mask peeling off the copper. It really fuses well.
