Abstract:
PROBLEM TO BE SOLVED: To provide an electrode structure achieving an adhesive connection structure inexpensively while simplifying a manufacturing process, and to provide a wiring body, an adhesive connection structure, etc. SOLUTION: In a connection structure C, a mother board 20 includes a rigid board 21 and an adhesive connecting electrode 22 formed on the rigid board 21. The surface of each of an electrode 12 and the electrode 22 is covered with organic films 15 and 25. The adhesive 30 includes conductive particles 36 dispersed in a resin composition 31 consisting essentially of a thermosetting resin. Electrodes 12 and 22 are in an electrical conduction state via the conductive particles 36. The organic films 15 and 25 are an antioxidation film formed by an OSP treatment and have a thermal decomposition temperature higher than the temperature in a solder reflow process. Since the organic films remain after the solder reflow, the solder connection structure and the adhesive connection structure can be formed smoothly. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To mount a component also on a rear of a connection with a FPC on a PCB connected with the FPC. SOLUTION: A wiring board module is provided with the connection where a conductor wire of a first wiring board and a conductor wire of a second wiring board are connected via an anisotropic conductive adhesive. The adhesive contains needle-like or chain-like metallic powder in insulation resin oriented in the thickness direction of the adhesion direction. In addition, a component is mounted on at least one of the first and second wiring boards, and is mounted on the rear opposite to a surface where the connection is formed.

Abstract:
PROBLEM TO BE SOLVED: To make a "rigid connection" of a boundary surface of an electrode connection part of a connection structure, constituted by connecting a 1st electrical structure and a 2nd electrical structure to each other with a conductive adhesive, through a thermosetting treatment, using the conductive adhesive without requiring any dedicated process by fusing metal particulates. SOLUTION: The connection structure comprises the electrode connection part whose continuity is secured by fusing at least one of a 1st electrode, provided to a 1st electric structure and a 2nd electrode provided to a 2nd electric structure and the metal particulates and an intermediate connection part which ensures the continuity of an intermediate part between the 1st electrode and 2nd electrode with the conductive adhesive, and the metal particulates are metal particulates which begin to be fused below the thermosetting temperature of the conductive adhesive, which contain a conductive filler of such a particle size that the filler will not be fused below the thermosetting temperature of the conductive adhesive.
