Homebrew PCBs

Alan,
Thanks for the encouragement!
Drilling went fine...I got the CEM boards so I wouldn't have to invest 
in a new drill press and carbide bits (maybe next trip to harbor 
frieght)so I just used my Dremel and a high speed bit and things went 
very smoothly. (This was on a layout designed by someone else. I also 
etched a board with my own layout created in Diptrace. I haven't 
finished drilling yet, but I can already see that I'll have to go back 
and increase the pad size on just about everything as some pads will 
only have the smallest of rings left once the hole is drilled.) 
Populating the board was pretty straightforward except for hunting for 
a couple caps in my junk pile. Everything works fine after I corrected 
one misplaced resistor and a solder bridge. This was a pretty simple 
transistor based audio circuit.
I used the two part H2O2 and one part HCL recipe for a total of about 
a cup of solution and was able to etch two single sided 1oz. boards of 
about 9 total square inches (one has a coppper pour and the other 
doesn't.) Not sure if there's any life left in the solution as it's 
about the color of engine coolant, but I'll give it another shot 
before I try to dispose of it.

Best of luck, Alan.
Chester
