Title:
ANISOTROPIC ELECTRICALLY CONDUCTIVE FILM, CONNECTION STRUCTURE, AND METHOD FOR MANUFACTURING CONNECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/121787
Kind Code:
A1
Abstract:
This anisotropic electrically conductive film 10A in which electrically conductive particles P are held in an insulating resin layer 2 has: a first array axis A1 in which the electrically conductive particles P are arrayed in the short direction; and a second array axis A2 in which the electrically conductive particles P are arrayed in parallel to the array axis A1, and those are arranged in parallel at a prescribed repeating pitch b. When the average particle diameter of the electrically conductive particles P is D, the distance between the first array axis A1 and the second array axis A2 is 0.7 D to 8 D, and the repeating pitch b of the first array axis A1 and the second array axis A2 is greater than 1.5 D. When a center distance d of the closest particles of electrically conductive particles P1 in the first array axis A1 and electrically conductive particles P2 in the second array axis A2 is greater than 2D, and the length of a projection image when the center distance d is projected in the short direction of the anisotropic electrically conductive film is f, an array pitch c1 of the electrically conductive particles P in the first array axis A1 is 2f or greater, and in the adjacent first array axis A1 and the second array axis A2, the electrically conductive particles P in the first array axis A1 and the electrically conductive particles P in the second array axis A2 are not superimposed in the long direction of the anisotropic electrically conductive film 10A.
