Detailed Product Description
Direct copper bonded (DCB) ceramic substrates:
DBC is a complex material, in which two layers of copper are directly bonded onto an aluminium-oxide(Al2O3) or aluminium-nitride(AlN) ceramic base. It has fine electrical insulation and thermal conductive properties, and has widely used in the power hybrids, power control circuits, power semiconductor modules, power supply modules, solid-state relays, high frequency switch mode power supplies(SMPS), electrical heating installations, semiconductor refrigerators, microware and military as well as aerospace technologies and other relative fields.
Features of DCB ceramic substrates:
1Fine mechanical strength, mechanically stable shape, good adhesion and corrosion resistant.
2Excellent electrical and thermal conductive properties.
3The number of thermal cycling reaches 50 thousands, high reliability.
4The themal expansion coefficient is close to that of silicon, So thermal resistance is very low, At same time, the production technologies can be simplified.
5May be structured just like printed circuit boards or IMS Substrates
6Operating temperature: -55 - 850
