Abstract

The invention relates to electronic paste for preparing a thick-film circuit. The electronic paste comprises a solid-phase constituent and an organic solvent carrier, wherein the weight ratio of the solid-phase constituent and the organic solvent is (65-90):(35-10), and the solid-phase constituent comprises graphene or the graphene and at least one rare-earth oxide. In the electronic paste for preparing the thick-film circuit, provided by the invention, a tiny amount of graphene or graphene particles are dispersed in a thick-film circuit layer and a thick-film dielectric layer, the electrical property, the thermal performance and the chemical performance of the thick-film circuit and the heat conductivity of a thermal interface in a thickness direction are improved at orders of magnitude by the micro fine lattices of the formed carbon micronano material, and the heat dissipation performance and the mechanical strength of a large-power thick-film integrated circuit are substantially improved.

Description

technical field [0001] The invention relates to an electronic paste for preparing a high-power thick-film integrated circuit, in particular to an electronic paste for preparing a heat source of a thick-film circuit chip. Background technique [0002] In the field of intelligent electric heat sources, electronic pastes for thick film circuits are usually divided into low-temperature electronic pastes: 65-250°C, medium-temperature electronic pastes: 250-600°C and high-temperature electronic pastes: 600-1200°C. The high-temperature heat source 600-1200 ℃ thick film circuit is the high-end level of intelligent heat source technology. Low-temperature heat sources have a wide range of applications, medium-temperature heat sources are not used frequently, and high-temperature heat sources are mostly used for special applications due to their complex technology and difficulty. [0003] Despite the rapid development of my country's general-purpose electronic pastes in the past ten y...
