Sounds like a good rule of thumb, or is that "rule of Clay" ;-)

So you did not have electrical test done on the sega multigame pcbs?

Yes, this is a single layer board. So the price quote I have is for single
layer. Also, the board will have a solder mask on the trace (bottom) side.
It adds very little to the cost to add the solder mask, so I am getting
that done. The solder mask helps alot when soldering components to the pads.
Since it is a single layer board, I will do a quick trace/pad continuity
test on each PCB I send to anyone ordering unassembled PCBs. That way, you
won't get a bum PCB.
