Hi,
Does anyone know of a machine that is able to measure inner layer 
expansion/shrinkage immediately after multilayer lamination ? Something like 
a machine that uses x-rays to locate the positions of fiducials at known 
coordinates on the panels and then generates the x/y shift with respect to 
nominal. Any information is appreciated.
