ABSTRACT:
Disclosed is a method of fabricating a microelectronic circuit package. The circuit package has a reinforced fluorocarbon polymer dielectric. According to the disclosed process, vias or through holes are formed in the composite by a process that leaves debris. The debris in the formed vias or through holes is reflowed in order to smooth the via and through hole walls for subsequent plating.
