Abstract
A film adhesive of a thermoplastic or thermosetting polymeric insulative material can be imparted with anisotropic electroconductivity by dispersing electroconductive fibrils of specified dimensions therein in orientation each lying within a plane substantially parallel to the surface of the film adhesive. The film adhesive is useful in adhesively bonding two circuit boards each having a plurality of electric terminals to be electrically connected each on one circuit board to the oppositely positioned terminal on the other circuit board. The orientation of the fibrils in a plane parallel to the surface of the film adhesive may be either unidirectional or at random.
