Everwide FK862F is a UV-curable adhesive designed for reinforcement and bonding in BGA, CSP, and electronic connectors. It prevents peeling and short circuits during bending, offering high mechanical strength and fracture energy absorption. The cured surface remains dry, dust-free, and non-tacky, making it ideal for high-speed production in electronics encapsulation.
