发明名称 Shaped material for use in sealing electronic parts
摘要 The present invention provides a film-coated shaped material for use in sealing an electronic part having high shape retentivity and prepared by blanking a film-coated epoxy resin sheet in a shape in conformity with the configuration of the electronic part, the epoxy resin sheet comprising a plastics film having a thickness of 10 to 1000 mu and a layer of a curable epoxy resin composition in a substantially uncured state and formed on one surface of the film, the epoxy resin composition comprising per 100 parts by weight of an epoxy resin, 5 to 50 parts by weight of a thermoplastic resin having a number average molecular weight of at least 5000, 5 to 300 parts by weight of an inorganic filler and a curing agent, and a chip sealing material flow preventing frame comprising the above film-coated epoxy resin. The present invention further provides a shaped material for use in sealing an electronic part, having high shape retentivity and comprising the film-coated epoxy resin sheet, the shaped material being thermally curable by two divided steps, i.e., a first step of gelling the shaped material at a temperature at which the material melts and adheres to an adherend without flowing out, and a second step of curing the epoxy resin composition at a higher temperature than in the first step without allowing the composition to flow out, and a chip sealing material flow preventing frame comprising the shaped material.
