Abstract
Process for producing circuitized greensheets including multi-layer ceramic sub-laminates and composites comprising thin ceramic greensheets carrying and thin, fine line patterned conductive metal layers. The invention comprises releasably-supporting the thin greensheets on a temporary carrier support having an ablatable release layer, preferably over a patterned conductive layer, and filling the vias with conductive metal paste, whereby the thin greensheets are supported against warpage and distortion. The supported greensheets are formed as single layers, pairs and stacks thereof, as desired, and thereafter separated from the temporary support for use.
