METHOD FOR FORMING A HIGH HEAT SINK INSULATION LAYER OF A METAL SUBSTRATES AND THE METAL SUBSTRATES PRODUCED BY USING THE SAME, CAPABLE OF IMPROVING WITHSTAND VOLTAGE, HEAT RESISTANCE, AND THERMAL CONDUCTIVITY

摘要

PURPOSE: A method for forming a high heat sink insulation layer of a metal substrates and the metal substrates produced by using the same are provided to form a second insulating layer by printing low temperature co-fired ceramics on the top of a first insulating layer.;CONSTITUTION: The surface of a metal substrate is processed through sanding. Ceramic is spread on the top of the metal substrate to form a first insulation layer. Low temperature co-fired ceramics is screen-printed on the top of the first insulating layer. A second insulating layer is formed by drying the low temperature co-fired ceramics and making them plastic. The low temperature co-fired ceramics are Bi2O3-B2O3-SiO2-TiO2 or Bi2O3-SiO2-Al2O3-TiO2.;COPYRIGHT KIPO 2011
