The present invention provides an anisotropic conductive film for testing
an electronic component, which comprises a film substrate comprising an
insulating resin and plural conductive paths insulated from each other
and penetrating the film substrate in the thickness direction,
preferably, an anisotropic conductive film wherein the plural conductive
paths are disposed in a houndstooth check pattern and the distance
between conductive paths between adjacent rows of conductive paths is
smaller than the distance between conductive paths within a row of
conductive paths. In another preferable embodiment, the insulating resin
comprises a naphthalene skeleton epoxy resin crosslinked with a phenol
resin and an acrylic rubber, and both ends of the plural conductive paths
are exposed on both the front and the back surfaces of the film
substrate.
