Patent ID: RE45092

Claim:
An anisotropic conductive connection method comprising: supplying an anisotropic conductive adhesive to a connection terminal of a wiring board; preliminarily connecting a connection terminal of an electronic component to the connection terminal of the wiring board while arranging the anisotropic conductive adhesive therebetween; and heating the electronic component while applying a pressure of 1 MPa or less to the electronic component to connect the wiring board with the electronic component and to completely or almost completely cure the adhesive; wherein the adhesive comprises: a binder resin composition and conductive particles that include a metal flake powder and are dispersed in the binder resin composition, wherein: the metal flake powder enables electrical connection between the connection terminals and the conductive particles due to surface connection; the metal flake powder has a major axis of 10 to 40 μm, a thickness of 0.5 to 2 μm, and an aspect ratio of 5 to 50; and an amount of the conductive particles contained in the anisotropic conductive adhesive is 5 to 35 mass %.
