Embodiment Construction

[0061] Below, with reference to accompanying drawing, give embodiment of the present invention, and illustrate the present invention in more detail, present embodiment has cited concrete material and numerical value as the best example of the present invention, but the present invention is not limited to this embodiment Example.

[0062] figure 1 An anisotropic conductive block 10 showing an embodiment of the present invention. figure 1 Although the anisotropic conductive block 10 of the present embodiment is a rectangular block, it is also applicable to blocks other than rectangular. The anisotropic conductive block 10 is formed by alternately arranging sheet members (hereinafter referred to as "non-conductive sheets") 20 composed of non-conductive members, and sheet members ( Hereinafter, it is also referred to as "zebra-striped sheet") 60 , 62 , 64 , 66 , and 68 . The sheet parts are bonded by a coupling agent. The zebra pattern sheet 60 is composed of non-conductive me...

Abstract

The present invention relates to an anisotropically conductive block, which establishes electrical continuity between electric terminals when it is interposed between the terminals, and its manufacturing method and is aimed at providing an anisotropically conductive block capable of offering conductivity independently in mufti-directions. The anisotropically conductive block (10) is configured by arranging conductive paths (e.g. (24) and (44)) while dislocating the paths in Z direction, wherein the conductive paths are non-conductive in a certain direction (Z direction) and have conductivity in a plurality of directions, in directions substantially in parallel with a plane (X-Y plane) perpendicular to Z direction.

Description

technical field [0001] The present invention relates to an anisotropic conductive block which is inserted between conductive terminals and makes the terminals conductive, and its manufacturing method. Background technique [0002] In recent years, a method of interposing an anisotropically conductive elastomer sheet between an electronic component and a circuit board to provide electrical conduction has been practiced. Here, the term "anisotropic conductive sheet" refers to a sheet that can have conductivity only in a specific direction (usually one direction). The anisotropic conductive sheet may exhibit conductivity only in the thickness direction of the anisotropic conductive sheet, or may exhibit conductivity only in the thickness direction when pressurized in the thickness direction. The latter has a pressurized conductive conductive part, and can realize a miniaturized electrical connection without using solder or mechanical fitting. In addition, it has the character...
