NON-FLOW RESIN COMPOSITION FOR UNDERFILL CAPABLE OF CONTROLLING THE CONTROL OF THICKNESS AND AREA, A NON-FLOW UNDERFILL FIM USING THE SAME AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A non-flow resin composition for underfill is provided to ensure viscosity of 500cps or more suitable for film coating and to accurately control the coating thickness and coating area of the underfill. ;CONSTITUTION: A non-flow resin composition for underfill comprises a thermoplastic epoxy prepolymer, a high temperature hardener, a thermoplastic resin for reforming and a melting material. A method for preparing a non-flow underfill film comprises the steps of: reacting an epoxy resin with a low temperature hardener at 80°C to obtain a themoplastic epoxy prepolymer; mixing the obtained themoplastic epoxy prepolymer, high temperature hardener, thermoplastic resin for reforming and melting material to blend a non-flow resin composition for underfill; and applying the non-flow resin composition for underfill to a base film.;COPYRIGHT KIPO 2011
