A method for fabricating an electronic device or component such as an anisotropic conductive film comprising: distributing a plurality of conductive particles into an array of microcavities formed on a surface of a continuous carrier belt, rotating the belt carrying the conductive particles while conveying a surface of an adhesive layer into contact with the surface of the rotating belt, transferring the conductive particles from the microcavities on the belt to the adhesive layer in predefined locations in the adhesive layer corresponding to the array of microcavities on the belt, and separating the adhesive layer from the surface of the belt. In one embodiment, the position of the microcavities is varied in a controlled manner.

Microcavity carrier belt and method of manufacture

Structures and manufacturing processes of an ACF array using a non-random array of microcavities of predetermined configuration, shape and dimension. The manufacturing process includes fluidic filling of conductive particles onto a substrate or carrier web comprising a predetermined array of microcavities, or selective metallization of the array followed by filling the array with a filler material and a second selective metallization on the filled microcavity array. The thus prepared filled conductive microcavity array is then over-coated or laminated with an adhesive film. Cavities in the array, and particles filling the cavities, can have a unimodal, bimodal, or multimodal distribution.
