摘要: A circuit board laminate includes a metal substrate, an insulation layer disposed on the metal substrate, and a metal foil disposed on the insulation layer. A metal-based circuit board includes a metal substrate, an insulation layer disposed on the metal substrate, and a circuit pattern disposed on the insulation layer. The insulation layer contains a liquid crystal polyester and 50% by volume or more of an inorganic filler. The inorganic filler is made of boron nitride and at least one of aluminum nitride and aluminum oxide. A proportion of boron nitride in the inorganic filler is within a range of 35 to 80% by volume.

摘要: The metal base circuit board according to the present invention includes a metal substrate, an insulating layer provided on the metal substrate, and a conductive foil for circuit formation that is provided on the insulating layer. The metal substrate has a thermal conductivity of 60 W/mK or more and a thickness of 0.2 to 5.0 mm. The insulating layer is formed using an insulating material composition in which an inorganic filler having a thermal conductivity of 30 W/mK or more is dispersed in a non-anisotropic liquid crystal polyester solution. According to the present invention, a metal base circuit board can be provided that can be applied in an inverter and applications requiring high heat dissipation properties, and that has high thermal conductivity, as well as having high thermal stability and electrical reliability.
