In determining your acceptance of x-outs, consider these points:
1. The cost probably will be higher if you say "NO X-outs allowed."
2. If you allow x-outs, and you are building surface mount assemblies, can
your pick and place equipment build the array and not place on the x-outs?
3. IF you allow x-outs, ask the fabricator to package the arrays with x-outs
separately from those arrays with no x-outs. This will help maintain
throughput at P/P
4. Solder paste reflowed on x-outs (no components) make good tools to
investigate solder coverage, solderability, and for use as inspection guides
to easily see silk-screen on dense assemblies.
my two cents worth
