Problems solved by technology

[0003] At present, the basic development direction of the high Tg copper clad laminate materials used in the industry is mainly to use the phenolic curing system, which performs well in the heat resistance of the material, and can basically meet the various performance requirements of the PCB for heat resistance. , although this type of material has the advantages of heat resistance, the material has insufficient toughness, peel strength and PCB processability, because the material is too hard and too brittle and lacks toughness, which makes it relatively large in PCB processability. The problem, but also increase the cost of PCB processing

Abstract

The invention discloses an epoxy resin composition which is prepared from novolac epoxy resin, isocyanic acid modified brominated epoxy resin, high-bromine epoxy resin, a phenolic resin curing agent, an epoxy resin curing accelerator, a heat stabilizer, inorganic filler and an organic solvent. A copper-clad laminate prepared by use of the epoxy resin composition disclosed by the invention has the characteristics of high glass transition temperature (higher or equal to 170 DEG C), good heat resistance and peel strength, good machinability and the like, and can meet the requirements for the heat resistance and processability of materials in a PCB (printed circuit board) processing process.

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and relates to an epoxy resin composition suitable for a lead-free high-Tg copper-clad laminate substrate material of high-density interconnection HDI and a preparation method thereof. Background technique [0002] Beginning on July 1, 2006, the official implementation of two EU directives (Restricting the Use of Hazardous Substances in Electrical and Electronic Products and Directives on Waste Electrical and Electronic Products) marks that the global electronics industry will enter the era of lead-free soldering. Due to the high soldering temperature, the thermal reliability of the copper clad laminate is correspondingly improved. The traditional lead-tin solder can no longer be used, and the soldering temperature required by today's tin-silver-copper and other alternative solders has been greatly increased. The traditional FR-4 copper clad laminate, due to its low heat resistance,...
