        Depending on the board size, and how stingy I am with my etchant (I often
put as little as possible) I get etch times ranging from 5 minutes to 20
minutes, using a "just let it sit in the acid and move it every couple of
minutes" method. The quality of the etch is quite good, and I've got the
time... TTYL
