[time-nuts] one-off PC board
I have a board layout that I need made, simple single-side, 2.3 x 6.5 inches. Any suggestions on where I can get this made at a reasonable price? The mask layout I have is a printout from a pdf document that has black where the traces are and is full-size. Others may be interested -- this is for Bob Cordell's state-variable low-distortion oscillator (similar to a Tek SG505), which delivers THD around 3ppm in the audio mid-band, works from 10 or 20Hz up to 100 to 200kHz, with generally very low distortion overall. A very nice inexpensive way to get great amplitude stability and ultra low THD, with output up to 10VRMS... I built this unit years ago, and now, after selling mine, I've discovered I'd like to have one again.

Many board houses offer a similar service. The caveat is that they all expect Gerber files rather than PDF. You might be able to call and see if they can take PDF as a special case. Otherwise try to dig up the CAD files that were used to create the PDF, or recreate the layout in Eagle, gEDA, PCB Artist etc and export as Gerber. Or skip the professional board houses and find someone with an etch tank who can help.

There's a guy in Berlin who offers such a service: http://www.prodigy-pro.com/diy/index.php?topic=37108.0. He started out mostly focusing on creating boards to repair/recreate older audio equipment, but he's turned it into a general PCB service. He actually prefers Illustrator, PDFs or even scans of boards over Gerber files. He's a musician, and his language may be a bit flowery at times, but there's nothing wrong with the quality of his work. Note that he doesn't do solder masks (yet), but neither will anyone else with an etch tank. This may or may not create leakage susceptibility, depending on your circuit and whatever post-treatment you give the board. JDB.

I don't think they can do anything with .PDFs, but if you can come up with Gerbers, check out http://www.batchpcb.com . Great service on 2-layer boards, somewhat slower on 4-layer boards since they take longer to accumulate a full panel from other customers. -- john, KE5FX -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on Behalf Of Dick Moore Sent: Wednesday, August 11, 2010 11:12 PM To: time-nuts@febo.com Subject: [time-nuts] one-off PC board I have a board layout that I need made, simple single-side, 2.3 x 6.5 inches.

Dick: I, for one, would be interested in knowing more about Bob Cordell's state-variable low-distortion oscillator. Do you soft copy details or a pointer to a source?
