Oh, and print off multiple copies.
If you don't, the one copy you have won't transfer right and you'll wish you had another copy.
If you do, then guaranteed, the first attempt will work perfectly
There's a guy called Murphy (who's a sod) that knows all about that
Indeed! I know Murphy well hehe. Since my transfer paper is A4 I will print 2 or 3 on one piece.
I think my first etch will be an LED driver for some high powered LED's, a nice simple project to start with for etching, is there a resource that I could look at that will tell me how much current 1 oz copper clad will handle at certain trace thicknesses?
