Applications for thermal circuit boards are largely in two main areas: Power conversion and Lighting. The Power conversion area includes such applications as motor drives and power supplies and typically involves the management of high currents and low voltage circuitry on the same board.
We are also the latest developments of EV power applications are seeing Silicon Carbide chips running at approximately 800v+ and 800 amps. The resulting operating temperatures are 200°C plus making the use of ceramics, with their high-temperature capability, and ideal PCB substrate choice. Equally, for EV the associated drive electronics are likely to be in Heavy Copper.
Effective thermal design and accurate manufacture are therefore the key elements for success and for optimum reliability. We at Daleba have considerable experience in this area together with the manufacturing expertise to meet even the most demanding requirements.
