Yeah, I might clean these up a bit. But the mousebite (that's what I
call them) pattern could be done better...

The cracker holes should be designed so that the nubs (left after
breaking) do not protrude beyond the PCB dimensions. This means that
there will fall inside the board and leave a mousebite which can be
about .010 inch, if designed properly. Hope this helps.

Subject: [TN] Question about cracker holes (panel breakaways)


We have been using panels with internal breakaways for over 20 years.
There is a slight amount of material left when they are broken but we
have never had a customer complaint about this.

We have started doing military business and they are rejecting
everything because the cracker hole areas exceed print dimensions.  It
is obvious that the additional material at the cracker hole location
does not have any impact to the end use.

Is there any industry standard that would permit the use of cracker
holes

Also has anyone had similar experiences dealing with military customers
and if so what was the end result?
