Abstract

The invention provides a thermal conductivity paste for screen printing with low viscosity, exothermicity, excellent storage stability and physical property of settability. The thermal conductivity paste is separated into A liquid containing acrylate resin and an epoxy resin hardener and B liquid containing epoxy resin and acrylate resin hardener. A thermally conductive filler is blended with one side or both sides of said A liquid and B liquid at a rate of 100 to 1000 weight section to total amount 100 weight section of said acrylate resin and an epoxy resin and the thermally conductive paste obtaining by mixing at a rate that a rate of a compounding ratio of said acrylate resin and an epoxy resin (however, weight %) is set to 10:90-90:10 before using said A liquid and B liquid.

Description

technical field [0001] The present invention relates to a thermally conductive paste (curable thermally conductive resin composition), and more specifically, to a thermally conductive paste used as an insulating material for a substrate. Background technique [0002] In recent years, as electronic equipment has become more functional and smaller and thinner, the density of chip components and semiconductors has increased significantly, and it has become more and more important to make the circuit board on which it is mounted with high heat dissipation. [0003] As such a highly heat-radiating circuit board, a method of mounting a heat-radiating fin on a heat-generating component using a heat-resistant adhesive is used. The so-called heat-resistant adhesive refers to an adhesive that is highly filled with an inorganic filler in a thermosetting or thermoplastic resin. Film-like heat-resistant adhesive made of permanent polyamideimide, thermosetting resin, and thermosetting el...
