 03 Dec 2006 7:46 UV and PCBs |
|
|
|
I'm having a hard-time with drawing my pcbs with markers, since whenever i'm etching, one face ends up etched, and another one good. Someone told me there's a method about "drawing" the connections with uv (and i believe a mask). What should i consider aquiring for this method? I do have a small UV lamp.
thanks.

| I've tried ironing yesterday on glossy paper, and it failed :/ Is there any other DIY method to make PCBs, except uv and ironing?

Most likely you don't try hard enough. See my post in this thread.

photo paper.
well, i've ironed 'em - one for 5 minutes, another for half an hour, and the last one, i let it alone, with the ironing machine over it for 2 hours. none works (but the last one did stank, and was really hot). each time i tried with both my old inkjet, and a laser from a friend. laser didn't work, but my inkjet (a lexmark z11) made some small tiny traces in the first two tries.

| Just a tip for you guys, if you're doing PCB the "ironing" way, print the PCB pattern in laser in greyscale mode (much darker) on a photo paper (plain paper will also work try it) iron on the copper side until marks of the PCB pattern reveals some of its traces on the back of photopaper (or plain paper) do this by applying pressure pressing on the PCB. After yer done, put it quickly on a lukewarm water with detergent solution, wait for the paper to be soften before peeling and then etch it.
