It depends on PCB I've been making PCB where track were 0.2mm wide. I don't think laser printer method could do this. Of course this particular PCB can be made with laser printer and glossy paper. Sometimes my decision depends on materials I have near by :) I am using both methods laser printer and UV exposure. It depends on PCB I’ve been making PCB where track were 0.2mm wide.

I'm using an etching process that requires less expensive materials, and no optical exposure. You might want to give it a try (laser printer + glossy photo paper to make the resist mask). Francis Hi,
