mik3ca Posted September 3, 2006 Report Share Posted September 3, 2006 Until now, I was using transparencies as the media to put my PCB artwork on in order to complete the photofabrication process.The PCB works excellent with a transparency, BUT, in order for this to happen, the artwork must be excellent. In most cases, it is not. When I pass the transparency (designed for inkjet printers) into an inkjet printer, it prints fine, but under bright light, I see random holes in my design (non-printable spots). For this reason, I need to pass the same transparency through the printer twice.The main problem I have with the second pass is that the two copies of the same design do not print one of top of the other. When this is successful (rarely), the image is darkened and no light can pass through it at all. My printer settings won't help because I already set it to the darkest setting.Now I am trying tracing paper. The price is excellent for each sheet, but the only problem I have with it is that it takes alot longer to remove the unwanted photoresist, and alot longer to expose the design and the board to light.With a transparency, I can expose a board and remove unwanted photoresist in an hour.I haven't changed the ratio of developer to water during both cases.I am wondering if there is better media to use to print the design on. I don't want to spend alot of money on it, and I want the media to work with an inkjet printer as well.any suggestions? Quote Link to comment Share on other sites More sharing options...
