I have been making PCB's using laser toner for a long time. With the right materials, I get good results. I've used up a batch of about 30 4"x6" boards, 1/2 oz. copper, that I got "on the cheap" over EBay.
Those boards mostly worked, most of the time, but on maybe 5 of them, I've had foils lift off the board, usually while soldering or desoldering, once for no apparent reason. So I'm looking for s source of better boards, maybe not so cheap this time.
Does anybody have a good reliable source of boards in a reasonable price range? If so, I'd sure like to hear from you.
