Ian,
All I can say is that if you haven't seen how some
people use the underscoring, it doesn't mean that it
doesn't exist. It's just a matter of time.
FYI designers here use very often undescore to make a
difference between two signals, not to make one of
them negative. RESET and RESET_ are just
Richard,
That is a good idea but unfortunately the printouts
are blackwhite.

Hi all,
I need to split a design that is presently one pcb into two. I will have to
add interconnect connectors, etc. Can this be done more readily in the
gerber phase by cut and pasting two different board designs into one? I
want the two boards to be fabbed at the same time and scored so

Mike,
It sounds like what you want is simply to combine the current boards onto
one panel. This is easy to do at the Gerber stage using CAMtastic. You can
also add the scoring or routing information and dimensions at that point. I
would avoid messing with combining schematics, there would likely
Mike,
I might be tempted to not do anything to the schematic at this time
besides add your two connectors. Add two connectors to your nets and route
the nets as normal. On your board, route the nets right across the split or
leave a gap along the score or break line. Then when you want
Ken,
the proper nomenclature would probably be slot. Can your
rectangular hole have rounded ends? If it can then it can be routed with a
40 mil routing bit. If not then you need a punched hole and that is much
more significant, talk to your fab house.
As for doing it with rounded
Mike,
You might simply add the mating connector pair to the schematic, and run
all required signals through both connectors. No net name changes needed.
Everything else is done in pcb layout. You end up with one board design
which is designed to break in two. You would wind up with some
Ken, I've done this by creating cutouts of the proper size (tiny)
using say four 1mil holes on 5mil pads. I included on the Drill Drawing
a detail showing routing a rectangular cutout from these sets of
1mil holes. You _must specify_ Plate Through for all these special
cutouts. Note that you

The best way to do this is to call your fab and ask them how they want the
information provided.
A slot, or rectangular hole, is done at the fab by using a routing bit -
usually after the board is complete, but before finish plating and
masking. Your fab will have its own procedures and
This is something we use frequently and it works ok the way you described
now. The only variation is that we don't route the whole board but the 2
boards separately , making sure the connectors are in the same position.
That is because we use a top schematic sheet which only has sheet symbols
and

Mike,
In my previous response I misunderstood your question. I had it the other
way around, going two boards into one. Oops, sorry.
Like the others posters are saying, keep the one schematic, add connectors
to existing nets, and route the traces right across the cuts. I think you
can ignore

Due to the way the net labels are attached to the wire

Thanks all,
It's a good sanity check to have so many others tell you what you suspect to
be the case. I like the drill idea and will use it.
