Abstract:
PROBLEM TO BE SOLVED: To provide a method of connecting electrical components permitting connection with a high throughput even when using an ACP. SOLUTION: As a method of connecting a first terminal row 6 that is provided in the connection part 5 of a first electrical component with a second terminal row 8 that is provided in the connection part 7 of a second electrical component in an electrically conductive manner, there is used a paste-like anisotropic conductive adhesive 1 with solder particles 3 and conductive particles 4 dispersed in a thermosetting resin 2. Using two-stage steps: a step of soldering and temporarily fixing both connection parts 5 and 7 with both terminal rows 6 and 8 aligned by the solder particles 3; and a step of permanently fixing both connection parts 5 and 7 by the heat-cured thermosetting resin 2, displacement is not caused to both terminal rows 6 and 8 in transferring from a device performing temporary fixing to a device performing permanent fixing.

Abstract:
PROBLEM TO BE SOLVED: To provide a lead-free solder paste having improved reliability. SOLUTION: The lead-free solder paste contains at least two kinds of metallic powders apart in melting points or melting point ranges from each other at least by 5 Kelvins. The quality of the solder paste is thereby additionally improved and particularly the tendency to void formation is reduced. COPYRIGHT: (C)2006,JPO&NCIPI
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.
