VERFAHREN ZUR HERSTELLUNG EINER VIELSCHICHTIGEN GEDRUCKTEN SCHALTUNG

摘要

Multilayer printed circuit boards are formed by providing a plurality of board assemblies having appropriate ground, signal and voltage planes. Each assembly is built around a dimensionally stable core to enhance registration between levels and is processed in such a manner that there exists a relative dimensionally stable configuration when performing method steps important to maintain good registration. The assemblies may constitute a completed multilayer board or may be subsequently combined to provide a more complex multilayer printed circuit board.
