Dyeing PCB

Dyeing a bare FR4 PCB plates

Sanded off the green solder mask down to the bare fiberglass board. Looked like this before dying. I wet sanded to avoid fiberglass dust.

Followed the iDye Poly instructions. Only dyed for 15 minutes. Also dyed the nylon screws and spacers at the same time.

I could have sanded more in the center areas of the top plate where it is a little lighter. Having a slightly roughed up surface helps the dye penetrate.

Overall, pretty satisfied with the results.
