Abstract
The present disclosure relates to an anisotropic conductive film (ACF) with controllable distribution state of conductive substance and a manufacturing method thereof. The ACF includes: a porous template, a plurality of conductive tubes, and an insulation glue layer. A plurality of through holes are configured on the porous template and to penetrate the porous template along a thickness direction of the porous template. Each of the conductive tubes is respectively inserted into one through hole and protrudes from the through hole at both ends, and the insulation glue layer is configured to wrap at least one protruding portion of the conductive tube protruding from the porous template. As such, the distribution state of the conductive tube may be controlled by controlling the density of the through holes within the porous template during the preparation process, and the distribution state of the conductive substances in the ACF may be precisely controlled.
