Etching circuit boards

morreale Friday 30 of September, 2011
Sylvia's Mini Maker Show has posted a short video on a Super Simple Copper Etchingmethod. It's great and easy since you don't need a photo step to put you pattern on to the copper. You just rub it on from a image created on a plastic slide printed with the patten from a LaserJet printer. Ferric Cloride is used to etch the copper. She right in that it makes a big mess. Don't use it in the bathroom sink. Mom's get very mad. The stains don't come out.
