Abstract:
An electronic component mounted member includes a circuit board, an electronic component connected to the circuit board and an electrically conductive adhesive interposed between the electronic component and the circuit board. In a joining interface of the electrically conductive adhesive and an electrode of the circuit board, an intermediate layer that is formed of a thermoplastic insulating adhesive with a softening temperature of 100null C. to 300null C. is interposed between the electrically conductive adhesive and the electrode. An electrically conductive filler contained in the electrically conductive adhesive is present partially in the intermediate layer, thus allowing an electrical conduction between the electrically conductive adhesive and the electrode of the circuit board. This electronic component mounted member is used, and when a repair is necessary, a portion of the intermediate layer corresponding to the electronic component to be repaired is heated so as to raise a temperature of this portion to at least a melting point of the thermoplastic insulating adhesive, thereby melting the thermoplastic insulating adhesive. Then, the electronic component is removed with this state maintained.
