摘要:
Provided is an electrical insulating resin composition capable of forming an electrical insulating layer which has excellent flexibility and board adhesiveness, together with high thermal resistance and high humidity resistance, tolerates a high temperature treatment at soldering and can be stably used for a long time under a harsh environment with high temperature and vibration in an automobile. A resin composition containing as organic components at least a rubber like polymer compound (A) composed of a copolymer of an aromatic vinyl compound and a conjugated diene compound and a polymerizable monomer (B) having one or more terminal reactive double bonds is employed as the electrical insulating resin composition. The compound (A) may be partially hydrogenated. The composition may optionally contain an oligomer (C) having a ring structure and having a reactive unsaturated bond in the molecule thereof.

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.

Provided are a gasket that is less likely to deform and installable with excellent workability when it is installed at a portion to be sealed and that can be produced at low cost, a method of producing the gasket, and a gasket installation method. A previously prepared thermoplastic resin film with a predetermined shape is placed in a metal mold composed of a stationary side metal mold and a movable side metal mold. Then, thermoplastic elastomer as an elastic body is insert molded on the film by an injection molding machine to form a gasket. After the molding, the gasket is removed from the metal molds.
