I want a special thru hole pad for soldering .05" ribbon cable right to the
pcb.
Such a hole doesn't seem to exist so I tried making one, it failed.
The hole filled in with copper and wasn't as big as I set the diam for
initially.
It was an elongated .025 diam via with a .02 hole size, prolly couldn't get
30awg wire in the hole the fab sent me..
Anyway the next pcb was .03 diam elongated via with .027 size hole and it
works ok, but there is not as much mask between the pads as i'd like when I
space them .05" apart.
Also, the hole size shrinks when you view it in layout and on the pcb the
fab sends back and i'd like it to be bigger.
I think that's where the problem is.
Maybe there's a limit on annular ring that's causing it?
