Homebrew PCBs

Hi Ted,

I posted a couple of pictures to the group.

http://ph.groups.yahoo.com/group/Homebrew_PCBs/photos/browse/a89e?c=

The board layout uses some very wide traces because I wasn't really 
expecting the results to be that good. I think the traces are 25 mil 
or 30 mil. There is some very fine lettering at the bottom of the 
board that did not transfer completely, but I did not expect that to 
come out at all, so it was a pleasant surprise.

I used the same method for the top markings, but they show an 
incomplete transfer. I think that's because I didn't really make much 
of an effort to prepare the surface, and if it was important to me, I 
would have redone it.

I don't know if 1/16'th is the thickest the laminator can handle, but 
it's probably as thick as I'm ever going to use.

Kevin
