The PVD Direct Plating Silver on ceramic dielectric filters is an advanced coating technology applied with 5G base station and other semiconductors for electronic industries. One typical application is Ceramic Radiating Substrate. Silver / Copper conductive film deposition on Aluminum Oxide (Al2O3), AlN substrates by PVD vacuum sputtering technology, has above all one big advantage compared to traditional manufacturing methods: DBC LTCC HTCC, which has much lower production costs. Royal Technology’s team collaborated with our customer to develop the PVD Silver Plating process successfully applying with sputtering technology which can replace conventional liquid silver brushing process.
