DCB Ceramic PCB for Solar Battery
DCB heat-sinking substrate is mainly applied to Concentrator Photovoltaic (CPV). DCB heat-sinking substrate for solar battery is fabricated by using bonding technology under high temperature. The conjuction between copper foils and ceramic is molecular linkage, without any adhesive or glue between copper foil and ceramic. Due to the great adhension between copper foil and ceramic substrate, DCB plate can suffer from harsh thermal cycling test, and isulating property and materail strength can last for several hundrd thousand hours under normal temperature. This is the special charcateristics belong to DCB only.
Becuase of ceramic material has high thermal conductive property, after bonding with copper foil, the whole DCB has a very low thermal resistance. In the succeeding manufacturing process, by the photoresist and chemical etching method and precision laser cutting technology, various accurate and complex trace patterns and outline can be produced on DCB heat-sinking substrate for solar battery.
