Etching DBC Ceramic Substrate for Semi-conductor Cooler  

Etching DBC Ceramic Substrate for Semi-conductor Cooler DBC Ceramic Substrate can be applied in various kinds of packaging of electronic module with possibility to etch various kinds of pattern on copper surface. At high temperatures, a copper foil substrate is bonded directly to the surface (single or double sided) of an AI203 OR AIN ceramic substrate. It is a green product without pollution and public harm, which also has a wide range of operating temperature. This substrate has many superiorities, for example, it is highly resistant to vibration and wear, ensuring its long service life. Also, A large number of high-voltage, high-power devices have high requirements for heat dissipation, and ceramic substrates have a better heat dissipation effect. Moreover, it has excellent electrical insulation performance, excellent soft brazability, high adhesion strength and a large current-carrying capacity. It is widely used in many fields, including electronic heater, automotive el…
