    摘要: A resin composition is provided that makes it possible to prevent low-heat resistant components from being damaged when heated in a process of mounting electronic components on a circuit board. There are also provided a method for easily repairing circuit boards that are determined to be off-specification products in the mounting process, and a method for separating and recovering useful circuit boards and/or electronic components from the circuit boards that are determined to be off-specification products in the mounting process. The resin composition comprises (A) 100 parts by weight of an epoxy resin, (B) 30 to 200 parts by weight of a thiol-based curing agent, (C) 5 to 200 parts by weight of an organic-inorganic composite insulating filler and (D) 0.5 to 20 parts by weight of an imidazole-based curing accelerator. According to the recovering method, the resin composition is softened by heating a part or whole of the circuit board in the mounting process, to a temperature in range not lower than the glass transition point of the resin composition and not higher than 110° C., and separating and recovering the electronic components from the circuit board.
