Hi guys, just thought i would tell you about my new way of pcb making. Step 1, Printing the artwork: using glossy advertising junk mail like bigW or K-mart papers tear out a clean page a bit smaller than A4, about 1cm from the top fold the top edge over and hook it onto a standard A4 sheet so the advertising is on the top side, and feed the lot into the paper slot of a brother hl-2040 laser printer and click print. the thin advertising wont jam like this because the normal sheet will pull it through. Step 2, Transferring the toner: find a laminator, the one i use is marbig A4 home laminator bought from safeway, it has silicone rubber rollers that can squash to accept a standard thickness bcb. cut out and align the artwork and feed it to the warmed up laminator. feed it in a couple of times to make sure the board all hot. Step 3, Etching: once the laminator spits out the board soak in hot water with dish wasking liquid and gently rub off bigW's advertising and etch the board. printers like the brother hl-2040 have really delicate toner so i have to be very gentle. any laminator should do, the only mod i did was take the top plastic cover off so i could get closer to the rollers for feeding tiny boards. any feedback would be great -Cheers!
