ESWIN's COF tape production line in Hefei starts mass production, opening up new vistas for the industry in the Chinese Mainland

On December 27, 2019, the mass production and delivery ceremony for ESWIN’s COF tape production line was held in Hefei Comprehensive Bonded Zone of Hefei Xinzhan Hi-tech Industrial Development Zone. At the ceremony, the COF tape samples were delivered to well-known IC design companies including Novatek, Solomon, and Raydium. This marks that ESWIN 's COF tape production has officially come into mass production, ushering in a new era for the COF tape industry.

According to Wang Jiaheng, Chairman of Hefei ESWIN Materials Technology Co., Ltd., the production of COF tapes, a key material in the integrated circuit industry chain, is still in embryo in the Chinese Mainland. To ramp up local production and self-sufficiency of COF tapes is the trend. After construction began in April 2018, ESWIN’s production line in Hefei came into mass production and delivered products to customers in just one and a half years. The production line fills the gap in the industry in the Chinese Mainland and will continue to deliver high-quality products and services to customers around the world.

With a total investment of RMB1.27 billion, ESWIN’s COF tape production line in Hefei has a designed capacity of 70 million pieces per month and will bring in annual revenue of about RMB1 billion at full capacity. The COF tapes it produces are mainly used for connecting semiconductor display chips and devices. As a key material for COF packaging, they are ultra-thin, light, highly integrated, and twistable and can be used in a variety of fields such as display devices, AI, Internet of Vehicles, and wearable devices.

The COF tape production line in Hefei has achieved localization of COF tapes in the Chinese Mainland, filling the gap in the industry. It marks another milestone in the Chinese Mainland’s semiconductor industry and is major breakthrough in the field of key materials for integrated circuits.
