1. Product Overview

LOCTITE® ECCOBOND UF 3810 is a one-component, fast-curing epoxy underfill designed for chip scale packages (CSP) and BGA applications. It offers:

  • Fast cure at moderate temperatures
  • High glass transition temperature (Tg)
  • Halogen-free composition
  • Reworkability
  • Stable electrical performance in temperature humidity bias
  • Room temperature flow capability

2. Applications

  • Underfill for Chip Scale Packages (CSP) and Ball Grid Arrays (BGA)
  • Provides mechanical reinforcement to solder joints and protects against thermal cycling stress
