To the group Most might know this but to correct scratches and other imperfections on TT I use a paint pen. I went to Hobby Lobby and got a Tree House Studio...
Is that something like a Sharpie? I've been using Sharpies for a while now, they are available in what they call a "Fine Tip" and an "Ultra Fine tip". If the...

Ken, This is real paint and comes in all collors. I think there are many brands of paint pens. The paint is very resistant to the etch solution. I used red...

Hi, While I'm an experienced design engineer, I've never done a PC board in 40+ years of design. We had a special department to do that. Now retired, I thought...
