I recently bought a DIY dry transfer Decal kit from this site:http://www.pulsarprofx.com/decalpro/
I have used a kit from this company for making custom circuit boards, and had success with that kit.
The short of that one is you print your image (PCB traces, pads, etc) in reverse on the provided transfer paper, run the paper over a PC board through a laminator, and drop em into water. The paper comes off the PC board, leaving the toner. Run a sealing foil over the PCB thru through the laminator. The foil adheres to the transferred toner. Then drop it in your etching system, and come out with your custom PC board.
It took me some trial and error to get it right, there was a learning curve. But before this I only used the breadboards from radio shack, I never etched my own board.
The decal kit uses similar techniques and the same hardware (a B&W laser printer, and a laminator.) But no etching.
I haven't had the time to try to make decals with it yet, but based on my experience with the PC board kit, I have high hopes.
Has anybody here tried/had any experience with this kit yet?
I'll post my results as I go along with it.
