Gathering experience with homemade PCB
October 19, 2008
Oi, yesterday and today I have been trying to make a homemade PCB using Eagle for designing the PCB and printing with a laser printer onto some glossy advertisement paper from junk mail. After several attempts I still haven't gotten a good transfer of toner to the PCB (check images) and I'm wondering if I should just design my PCBs and then send the design files off to Olimex for production
The leftmost board was made using normal magazine glossy paper which is about as thick as normal printer paper. That paper seemed to stuck a bit too much to the toner - I did try that type of paper once more (middle board) and heated it a bit longer than before but still the transfer was incomplete. On the rightmost picture I used thin glossy advertisement paper and that seemed to wrinkle up when exposed to the heated iron and the final board was both filled with cases of lacking traces and traces that were smeared into the surrounding ground layer.
Close but no cigar! I did find out that in order to print on the glossy thin paper I needed to tape it to a normal sheet of printer paper so it wouldn't jam in the printer.
I might give this another go but Olimex is looking better and better by each failed attempt!
