DBC Copper Cooler

The DBC copper cooler consists of several layers of pure copper foil into which different, very fine structures are etched. These layers create three-dimensional structures for efficient cooling in power electronics. The design of the different layers can be adjusted to customer-specific requirements.

During the curamik bonding process, the different layers are connected to each other. This process does not use any additional soldering or adhesive layers that would negatively influence the cooler's thermal resistance.

For special applications such as laser diode cooling, the surface can be diamond-cut to achieve the best possible evenness for soldering on the laser diode.

DBC copper coolers are used for high performance laser diodes at 20 - 100 Watt. Additional applications are for example in IT (CPU cooling) or medical technology (LED light sources).
