i concur with this
i can say from experience that running traces through the breakaway area
is problematic
ok for protos maybe
the traces tear and flop around, sometimes peeling way back
for limited production you could dremel a 'wide' area of the trace and
then break away

I would use a ribbon cable that was previously suggested, or use a
flex circuit. Running traces to the edge of a board would cause lamination
and corrosion problems. If the copper is run through the tab and then the
board is snapped apart that copper track will be exposed on the edge. Also
rts together. Perhaps you should consider an IDC
connector between the two.

I used via/hole size of 1mm/0.7mm. Could be smaller if they had sharp tool for
V-grooving.

> Hello
Hello, all:
We have had our domain transferred to a new ISP last week, so e-mail has
just begun working normally (I hope!).
Anyway, I want to make a PCB that has a "break-off" area with extra
circuitry on it. The idea is that some users may not need the extra
circuitry, so they can break off th
