Problems solved by technology

[0004] In the above flame retardant technology, the method of adding inorganic phosphorus and organic phosphine compounds will reduce the moisture resistance and cause a decrease in reliability. The use of metal hydroxides will cause a decrease in fluidity and mold release, and increasing the proportion of fillers will also lead to fluidity. falling problem
[0005] In addition, when hydroxide is added as a flame retardant in semiconductor packaging materials, a large amount needs to be added to achieve V-0 level, resulting in a decrease in the fluidity of the material. Since hydroxide has a large amount of hydroxide, Will cause the material to stick to the mold

Abstract

The invention relates to a resin for semiconductor packaging, and particularly relates to an epoxy resin composition which contains a composite flame retardant and can improve soldering resistance of an epoxy resin composition molded material. The epoxy resin composition comprises the main components and contents: 3.5-15 wt% of epoxy resin, 3.1-10 wt% of phenolic resin, 65-87.5 wt% of a filler, and 2-10 wt% of the composite flame retardant (containing zinc molybdate, zinc borate, magnesium hydroxide and aluminum hydroxide). The epoxy resin composition containing the composite flame retardant is a semiconductor packaging material with excellent soldering resistance, and moreover, also has necessary liquidity, moldability, flame retardance and mechanical properties.

Description

technical field [0001] The invention relates to a resin for semiconductor encapsulation, in particular to an epoxy resin composition containing a composite flame retardant which can improve the solder resistance of epoxy resin composition molding materials. Background technique [0002] In recent years, due to environmental protection requirements, the solder used in the installation of semiconductor integrated circuits or discrete devices is being promoted to be "lead-free". Correspondingly, the infrared reflow temperature of soldering has become higher, which requires packaging materials to have higher solder resistance. ; At the same time, the bromine-antimony flame retardant system in the traditional epoxy resin composition for semiconductor packaging will no longer be used, and it will be replaced by an environmentally friendly flame retardant technology. [0003] In response to the above-mentioned needs, there are methods using red phosphorus (see JP Unexamined Publica...
