Simply a question of yield and expense. If the board fab can make panels with zero errors, and you are willing to pay for them, then go with no X-outs. Keep in mind that if you are going to use waste as a parameter in this tradeoff that the board fab will be tossing out whole panels rather than have you waste solder on a couple of ups.

Subject: [TN] X-Out Policy
These is a debate currently raging on internally on whether or not to allow X-outs on panelized assemblies. I am of the opinion to not allow any X-outs as this entails manual intervention on the line to not populate that particular board (we have not programmed any bad board sense into our programs), and to a lesser extent, leads to solderpaste wastage. Furthermore, to me, accepting X-outs means accepting a more variable (if not a out of control) process at the board house. However, I want to to hear to any opinions otherwise if any
What is the industry doing as a whole regarding X-outs?
Thanks,
Amol
