Aluminum Oxide PVD Plating Copper System

    The DPC process- Direct Plating Copper is an advanced coating technology applied with LED / semiconductor / electronic industries. One typical application is Ceramic Radiating Substrate. Cooper conductive film deposition on Aluminum Oxide (Al2O3), AlN substrates by PVD vacuum sputtering technology, compared with traditional manufacturing

methods: DBC LTCC HTCC, much lower production cost is its high feature.

Royal technology team assisted our customer to developed the DPC process successfully with PVD sputtering technology.
