DBC heat-sinking substrate for solar battery is fabricated
by using bonding technology under high temperature.
The conjunction between copper foils and ceramic is molecular
bond and any adhesion agent is not being used.
Due to the fine adhesion between copper foils and ceramic plate.
it can suffer from strict thermal cycling test.
under the normal temperature environment,the islation performance and material
strength can hold several hundred thousand hours stability.
Other materials can not compare to this on.
Because the ceramic material has fine thermal conductive preperty
the compound material has low resistance.
In the succeeding processes,by the photoresist and chemical etching methods and fine laster cutting process.
DBC heat-sinking substrate for solar battery possesses various accurate
and complex patterns and outlines.
