Abstract

An epoxy resin composition is provided, and the composition comprises an epoxy resin, a phenolic resin, a catalyst, a filler, optionally a defoaming agent, and optionally an additive. The epoxy resin composition can be used in various electronic applications, such as surface mount device package, such as SOP8, SOP14, SOP16, SOP20, SOP28 package.

Description

technical field [0001] The invention relates to an epoxy resin composition, its preparation method and application. The epoxy resin composition of the present invention can be used in various electronic applications, such as surface mount device packaging, such as SOP 8, SOP14, SOP16, SOP20, SOP28 packaging. Background technique [0002] Voids can be easily found on the outside and inside of semiconductor packages of epoxy molding compounds. The presence of voids can lead to various effects. For example, external voids can affect package appearance, while internal voids can act as weak points leading to poor attachment and thermal fatigue, thereby affecting package performance and lifetime. [0003] Therefore, it is very important to reduce the number of voids in the package. In order to reduce the number of voids in epoxy molding compounds (EMC), much work has been done by different methods. [0004] Kuo-Yuan Lee and co-workers, in U.S. Patent No. 20120077312 A1, provid...
