Re: Question about etching boards

I made it out of "plexiglass". Initially, I used aquarium sealer but it didn't like the heat so I re-did it with a fusing cement I got from TAP http://www.tapplastics.com/shop/product.php?pid=130& <p>If you use plexiglass, make sure to get the special knife to cut it. <p>My tank is about 9"x9"x 1" (...

I don't bother with single sided any more because I like the other side to be a ground plane. You should start with single sided, though. <p>All you need is a ...
