MAKING THE BOARD: Print the PCB on the picture paper and cut to size Cut copper to match paper size Clean the copper (very important part) I use wet sand paper, you can use ajax as well Wipe copper with denatured alcohol put paper on copper. heat iron on max heat put a paper towel over paper and board. press iron straight down center of iron on board * hold for 30 seconds * remove iron for a couple second and repeat * straight down and hold for 30 seconds * (that part make the paper stay in place on the copper) now slowly iron for 30-60 seconds, make sure you get the edges of the board, they are the hard part. After done, let it cool (turn of that iron too) Get a cup of warm water, sometimes a drop of dish soap (soap is not required) drop in the board. Wait 5-10 minutes. replace warm water with board in cup, and use thumbs to rub the paper off layer at a time, sometime paper falls off (but not often) with thumbs remove any paper film. ETCHING THE BOARD: You can use a plastic flat bowl or a ceramic (if ceramic you can warm the ferric chloride as that helps) fill enough to submerge the board. I put the board face down but make sure you move it around and the face is under the acid. If you move it on occasion for about 15 minutes, with the plastic knife, you will see the copper is gone. remove it, rinse it. I use acetone to remove the toner clean up my mess and drill the board with my old dremel press.
