Dexerials Eyes Particle-Arrayed ACF as Standard for Smartphones

摘要

Dexerials Corporation has been endeavoring to make its particle-arrayed anisotropic conductive film (ACF) ArrayFix® a de facto standard in the smartphone market. ArrayFix is suitable for the connection of fine circuits compared with existing ACFs. The company plans to expand sales of particle-arrayed ACFs to the scale of ¥10 billion (US$93.1 million) by FY2023 ending March 2024. The particle-arrayed ACF commercialized by Dexerials is a joining material, which can stably connect many wirings even in a small space, by arraying conductive particles at the target position. It is suitable for chip-on-glass (COG) connection in which driver IC is mounted on the glass substrate of a display panel. It enables minimum wiring interval of 10μm. Thus, it enhances the accuracy of bonding inspection performed by image processing after mounting, and contributes to the improvement of production yield.
