Good Day,

There is an alternative method to the two methods of manufacturing printed circuit board you mentioned, and that is the draw by hand method. I used that method to make my two amplifiers (stereo). It's a relatively time-consuming task and requires a fair bit of patience. But you can correct a mistake before etching the board. All you need is a permanent ink marker. Just draw on the board the tracks and place the board in Ferric Chloride solution.

Yahoo has a PCB Bulletin board/group --

I have done small boards on an HP Plotter -- but you have to own a plotter! You can do the same by hand as suggested above -- you need a water-proof marker.

you can also "dead-bug" your designs -- tack the IC's to the copper with a bit of hot-melt adhesive and wire the components in the air -- in fact this method results in very low parasitic capacitance and ham radio operators use it for prototypes of all sorts of equipment even into the VHF region.

Hi jackinnj

I am considering building a phono stage, maybe "dead bug"[ interesting and comical expression. I have some thin copper sheet, also that thin brown [fiberglas?] board. Would these be suitable for the dead bug method? There will be an opamp socket to attach.

cheers
doggy

How about the toner transfer method? If you have access to a laser printer and some photo paper, you run the design on the photo paper and iron it onto the board, then etch. See this for full instructions.

whats wrong with fotoresist boards? if u can get em there is no problem to make a high quality boards . u dont have to use UV light to expose em , i always use sunlight with great results

Note: I have no connection whatsoever with the companies mentioned in the following post.

I use to use the Peel'n'Press Blue paper and to good results, but often not very consistant from one time to the next.
http://www.techniks.com/

I recently switched to Toner Transfer System from Pulsar and the results are even better. Really consistant. And I also bought the toner applicator (A GBC plastifier I modified following their instruction) and it cut a lot of the guess work about the ironing part of the process.
http://www.pulsar.gs/

With this method and a DIY etching tank I get PCB's in around half an hour turn time including the tank warm up time.

Hard to beat and incredibly cheap!

Hope this helps!
Sébastien

I've seen some jet printers that can print directly to a CD.
Maybe they can print directly to a PCB.

I've have used the laser printer & inkjet paper way for years with excellent results.
See my link at Head-fi forum

Unfortunately the inks used in inkjet printers are water soluble and cannot be used for PCBs

I use the inkjet photo glossy paper for the toner transfer (printed with laser printer!). It works fine. For example I obtained in this way the PCB visible in this thread
