ACF IMPROVED FIXED ARRAY ACFs WITH MULTI-TIER PARTIALLY EMBEDDED PARTICLE MORPHOLOGY AND THEIR MANUFACTURING PROCESSES

摘要

As the anisotropic conductive film (ACF) (a) an adhesive layer having a substantially uniform thickness; And (b) a plurality of conductive particles individually attached to the adhesive layer, wherein the conductive particles have a first non-anomalous alignment of the particle sites partially buried at a first depth in the adhesive layer, A second fixed non-anomalous alignment of the conductive particles embedded with the first conductive layer, wherein the first depth and the second depth are distinctly different; Or a dispersion of conductive particles completely embedded in the adhesive layer. The ACF can be supplied as a sheet, a continuous film or a roll, and the multi-stage morphology can be over the entire length of the product or in the selection area.
