DPC ceramic PCB / Alumina Oxide (Al2O3) PCB, Aluminium Nitride (AIN) PCB Copper Plating by PVD

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 collaborated with our customer to developed the DPC process successfully with PVD sputtering technology.

Applications of DPC:
HBLED
Substrates for solar concentrator cells
Power semiconductor packaging including automotive motor control
Hybrid and electric automobile power management electronics
Packages for RF
Microwave devices
