Description

This image can be cut on a vinyl cutter, then attached to a copper clad board before etching it.

The traces you get from this process are really well defined.

If you put the board in a jar, you can agitate it very well with much less hazard of splashing.

Instructions

Cut the image on a vinyl cutter. You can use the black and white .jpg file or the .svg file to get your cut contours.
Weed the sticker of unwanted parts.
Rough up the surface of the board with a pot scrubber or similar.
Stick the vinyl to the copper clad board.
Etch the board in ferric chloride.
Rinse, and populate your board.


The way this board was designed, you can use traditional through-hole components, but you solder them to the board as if they were surface mount components.

If you need to connect pads, you can solder a wire between the pads you want connected.

If you don't have access to a vinyl cutter, you could do a couple of things:
Cut it by hand with a utility knife
Bring your design to a sign shop and see if they are willing to cut it for you
Send out to a service, have them cut it and ship it back to you.

Excuse my curiosity, the image is of any use?

Anyway I think the shape is not correct, for very small things can be useful for more complex causes problems, advise a preferred vinyl matte black color gives more grip in the emulsions and peeling.

This is a great method.

I did some boards with this method about a year ago. One thing I discovered was that if you weeded the vinyl after transferring it to the copper clad board the parts and traces stayed better aligned.
