en.Wedoany.com Reported - Chinese companies have achieved fully independent and controllable mass production across the entire supply chain for ACF anisotropic conductive adhesive film, with product performance comparable to high-end Japanese imported models, some core parameters surpassing them, and prices at only about 60% of similar Japanese products.

ACF anisotropic conductive adhesive film is a key material for connecting screens, chips, and touch modules, responsible for precisely transmitting electrical signals. This material has high technical barriers, requiring precise control of conductive particle distribution at the micron level while balancing conductivity, insulation, high-temperature resistance, and stability.

Over the past 50 years, this technology has been primarily monopolized by Japanese companies. Hitachi, Sony, Sumitomo Chemical, and others once held over 90% of the global ACF market share. Domestic high-end panel manufacturers and semiconductor packaging companies have long been forced to accept high prices and limited supply.

Leveraging their technological monopoly, Japanese companies have long adopted a high-price strategy, often citing insufficient production capacity or technical confidentiality to impose limited or tiered supply on companies from various countries.

Domestic companies have conducted research and development in core ACF formulations, precision coating, particle arrangement, and curing processes. After thousands of experiments, they have overcome challenges such as precise Z-axis conductivity, absolute XY-axis insulation, and long-term high-temperature stability. Leveraging the advantages of the domestic industrial chain, domestic ACF reduces production costs while ensuring performance, with stable supply and shortened delivery cycles.

Domestic ACF has entered the supply chain of leading domestic panel manufacturers and semiconductor packaging companies, achieving batch substitution. Its application scope covers smartphone screens, foldable screens, automotive high-definition touch screens, precision semiconductor packaging, and industrial control display equipment, with market penetration continuously increasing.

ACF is a fundamental core material throughout the entire field of electronics manufacturing. The change in its monopoly landscape may challenge Japan's advantages in niche areas such as optical films, packaging materials, and precision colloids.
