Description

technical field [0001] The invention discloses a preparation method of an aralkyl epoxy resin material used for sealing semiconductor equipment, and belongs to the technical field of chemical materials. Background technique [0002] A semiconductor is a material whose electrical conductivity is between that of a conductor and an insulator at room temperature. Semiconductors have a wide range of applications in radios, televisions, and temperature measurement. With the development of high-density mounting of electronic components on printed circuit boards, semiconductor devices have changed from pin-type packages to surface-mount packages. In addition, surface mount ICs, LSIs, etc. have become thin and small packages in order to increase the mounting density and reduce the mounting height. Therefore, the area occupied by the components in the package increases, and the thickness of the package becomes very thin. In addition, with the multi-functionalization and large-capaci...
