    摘要: 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 100° C. to 300° 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.

    摘要: A mounting technique with improved adhesive strength and higher reliability against bending stress is provided with the use of a conductive adhesive including a binder resin and a metal filler as main components, in which a functional group is introduced into the molecular chain of the binder resin to form a multidentate bonding with an electrode metal easily. As a thermoplastic resin, at least two kinds of functional groups selected from the group consisting of a carbonyl group, a carboxyl group, an amino group, an imino group, an iminoacetic acid group, an iminopropionic acid group, a hydroxyl group, a thiol group, a pyridinium group, an imido group, an azo group, a nitrilo group; an ammonium group and an imidazole group are introduced. Accordingly, a strong bond with the electrode metal can be achieved. The conductive adhesive is screen-printed to an electrode disposed on a substrate, and after an electrode of a component is mounted, the structure is heated so as to create a mounted structure.
