I have just spent a whole day trying to make my first PCB (2sided) via toner transfer method, close to what's described in this post.
I finally got all the bugs worked out of my system, then went on to drill the holes in the first side, so I can align the second side to it, and I screwed it up. Totally thrashed the backside of the copper as the bit was coming out. I am using a hand drill and a small drill bit (probably NOT carbide, found it on my garage floor). I have deduced that I need a carbide bit, but do I need a Dremel? I already have a hand drill...
How fast should I be going? I was going really slowly. Should I apply alot of pressure? I saw a guy on youtube using a hammer & punch to make starter holes - seemed kinda stupid to me, but is that really a good idea? Could I have possibly made the copper brittle by heating it too much/too long, or by brillo'ing the hell out if?
On a side note - What do you use to coat the PCB after it's done and before you solder your components? Most professionally made PCBs have a lacquered look. how much insulation does this coating provide?
