Dielectric Coated Metal Substrate Optimizes Performance

Overview
Bergquist IsoEdge technology enables the use of highly optimized heatsink designs that can effectively increase 3-D packaging densities, reduce part counts and simplify labor at assembly. IsoEdge replaces older, flat-based heat sinks and individual insulators used in combination to meet safety agency criteria. Past designs limited packaging densities and performance and required time-consuming assembly, hi-pot testing and safety approvals. A thin coating of IsoEdge thermally conductive and electrically isolating dielectric provides excellent heat transfer with inherent 3-D electrical isolation to meet stringent safety agency requirements.
Bergquist Thermal Clad IsoEdge Heat Plates minimize thermal impedance and conduct heat effectively and efficiently in high watt-density DC/DC converters.
