Karl, My experience with panelized boards says that you are experiencing a very high fallout for a 2 layer, 2 up panel. I would get to the root cause of the reject rate right away or change suppliers. We've used "press-in" panels from time to where the routed boards are inserted to a routed frame, but no glue in boards. I would think the labor to glue the boards would be quite high as is the press-in process. I'd expect that you would experience problems in insertion, onsertion or at soldering where the heat might effect the "glue".

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!
