DBC substates is used to produce electronic devices such as resistor card, surface mount devices, hybrid integrated circuits and sensors by silk Screen printing technology and following process drying/curing, firing, and laser trimming of resistors. The finished super-thin DBC substrate has excellent electrical isolation,high thermal conductivity, fine solderability and high bonding strength.
As a new and high capability substrate, DBC substrates have been used widely in electric power and electronicindustry. ln
addition, all products can be nickel plating or gold plating. We can according to customer's requirements to customizedthe DBC of various sizes, specifications and have holes.
