Homebrew PCBs

I've used it to mask the back side which I didn't want etched.

The problem is that the etchant gets in along the edges of the tape
unless you press them down really really well.

Best to try a small piece first to see if your tape/etchant will
exhibit the problem or not. Also clean the board beforehand.

If all else fails mask negative, spray-paint, and peel the tape away
before etching.

Did you know some types of veroboards/stripboards are very efficiently
milled/cut and not etched? That may be an option for you.
