Dbc Aln Plate Direct Bonded Copper Ceramic Substrate - China
price: 3.55 Dollar US$
DBC ALN Plate Direct Bonded Copper Ceramic Substrate Product Description: Material: Ceramics
Place of Origin: Guangdong, China Product Applications: Cooling, heat dissipation Package: Standard export package
Paymant terms: T/T, L/C, Paypal, Direct bonded copper (DBC) substrates are commonly used in power modules, because of their very good thermal conductivity.
They are composed of a ceramic tile (commonly alumina) with a sheet of copper bonded to one or both sides by a high-temperature oxidation process (the copper and substrate are heated to a carefully controlled temperature in an atmosphere of nitrogen containing about 30 ppm of oxygen; under these conditions, a copper-oxygen eutectic forms which bonds successfully both to copper and the oxides used as substrates).
The top copper layer can be preformed prior to firing or chemically etched using printed circuit board technology to form an electrical circuit, while the bottom copper layer is usually kept plain.
The substrate is attached to a heat spreader by soldering the bottom copper layer to it.
