The present invention relates to a reworkable epoxy resin composition, more specifically, (a) 0.1 to 10 parts by weight of monofunctional epoxy resin; (b) 10 to 50 parts by weight of the bifunctional epoxy resin; (c) 5 to 50 parts by weight of a trifunctional or higher polyfunctional epoxy resin; And (d) 20 to 60 parts by weight of an acid anhydride curing agent; wherein the monofunctional epoxy resin or the bifunctional epoxy resin is an epoxy resin composition comprising an epoxy resin having a flexible structure. . According to the present invention, it has excellent processability, electrical, mechanical, and chemical properties of the existing liquid epoxy material, and can be reworked, and the epoxy resin composition on the substrate is completely released during the process so that no residue is left. Workability, productivity, and reliability of the composition user can be obtained. |
