We approach X-outs from a quality and business sense standpoint:  If
     we allow no X-outs, then that is what we will get, however, our
     sub-panel price will increase due to the higher scrap rate at the PCB
     supplier.  Too many X-outs on a sub-panel cause headaches for assy.
     even though they can account for the X-outs in programming.  The
     trade-offs have produced a 5% X-out typical for sub-panels which
     typically contain 100 pieces on them. 2%-7% is the typical working
     range.  High production volumes would bring this down in to the 1%-3%
     range.
