PCB - Post processing

So. Here is a little trick to post process a homemade PCB board.
This is valid for both mechanical and chemical echting.

This is a small USB bit whacker I made for quick prototyping. Well it's not that small but this is a first version and it's a single side board.

1º Step - DRILL
First step if you are not making the drilling with your CNC or you are making an chemical echting make all the drills on the board.

2º Step - DEBURR
Use a very fine grain sandpaper or oil stone do deburr all imperfections off the PCB. That will make it look like this photo.

OK don't mind that accidental cut on the pad...uugghhh. Looks very scratched doesn't it?
Let's make it pretty.

3º Step - "KIND OF" THIN PLATING
Hummm..thin plating finish would be nice. Well you can do something very similar. Apply a silver iodide (silver nitrate based compound) used to repair and clean jewelery. Here in Portugal there's a product called Pratex.
This will also ease the soldering work.

Here is a photo.

Nice!!
Despite the...uuuggghhhh...accident...uuuuggghhh (rush is your enemy). Looks quite good.
