Abstract:
This invention relates to a process which produces flat, distortion-free, zero-shrink, low-temperature co-fired ceramic (LTCC) bodies, composites, modules or packages from precursor green (unfired) laminates of three or more different dielectric tape chemistries that are configured in an uniquely or pseudo-symmetrical arrangement in the z-axis of the laminate.
