Product Description

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.

Key Features

  • Excellent adhesion to various plastics and metal connectors
  • Prevents peeling and short circuits under mechanical stress
  • Fast UV curing for mass production applications
  • Non-tacky, dust-proof cured surface
  • Complies with 2011/65/EU RoHS regulations
  • Low halogen content (Cl < 900ppm, Br < 900ppm, Cl + Br < 1500ppm)

Recommended Applications

  • Connector reinforcement in electronics
  • Encapsulation of BGA and CSP components
  • Bonding of PVC, PET, PI, and metal connectors
