  • Microcavity carrier with image enhancement for laser ablation
    Patent number: 9352539
    Abstract: A carrier belt for fabricating a device or component such as an anisotropic conductive film. The carrier belt includes a substrate having a sacrificial image enhancing layer. Microcavities are formed in the carrier by laser ablation through the image enhancing layer. After the image enhancement layer is removed, a plurality of conductive particles are distributed into an array of microcavities formed by laser ablation on a surface of a carrier belt and transferred to an adhesive layer. The image enhancing layer enables one to form microcavities with a fine pitch and spacing and partitions having a high aspect ratio.

  • FIXED ARRAY ACFs WITH MULTI-TIER PARTIALLY EMBEDDED PARTICLE MORPHOLOGY AND THEIR MANUFACTURING PROCESSES
    Publication number: 20140141195
    Abstract: An anisotropic conductive film (ACF) comprising: (a) an adhesive layer having a substantially uniform thickness; and (b) a plurality of conductive particles individually adhered to the adhesive layer, wherein the conductive particles include a first non-random array of particle sites partially embedded at a first depth within the adhesive layer and a second fixed non-random array or dispersion of conductive particles partially embedded at a second depth or a dispersion of conductive particles fully embedded within the adhesive layer, wherein the first depth and the second depth are distinctly different. The ACF may be supplied as a sheet, a continuous film or as a roll and the multi-tier morphology may be present throughout the length of the product or in select areas.
