▼Description of Ceramic Substrates DPC
Direct Plated Copper (DPC) is the newest development in the field of Ceramic Substrate PCBs and using this method can result in copper thickness' ranging from 10um (≈ 1/3oz) to 140um (4oz). With DPC track printing and etching is then performed with the thin Copper allowing for very fine tracks and reduced undercutting.
DPC Ceramic Substrateis the long-proven standard for power electronic modules in industrial, home-appliances and automotive applications. Unipretec ceramic substrates DPC have an excellent performance/cost efficiency ratio. The great heat conductivity ofAl2O3 (25 W/mK)andAlN (175 W/mK)as well as the high heat capacity make the substrate irreplaceable in power electronics. The thick copper foils offer extremely good electrical and thermal conductivity and form an outstanding base for the soldering and wire bonding processes.
