We are currently using a 2 layer FR-4 board as a 2-up panel in our assembly 
factory and our board vendor has asked us if we are able to use x-outs. 
 Currently, we are not able to use x-outs given our equipment and line rate. 
 They say that this problem is causing 6%-8% fallout and want to increase 
our cost.  Consequently, our vendor has asked us if we can accept boards 
that have two good boards glued together into a panel.  They claim that 
there will be little difference between the panels and want to move forward 
with a trial run.

Does anyone else produce / use glued boards?
Is this fallout unusually high?
What are some problems we should look out for?

Any information is greatly appreciated!
