- Question & answer
LOCTITE® ECCOBOND UF 3811 is a halogen-free, reworkable, low-viscosity epoxy underfill specially designed for Ball Grid Array (BGA) and Chip Scale Packaging (CSP) applications. It flows at room temperature with no additional preheating required, and cures quickly at moderate temperatures to minimize stress to other components. When cured, it has a high glass transition temperature while maintaining flexibility, so solder joints are protected during thermal cycling and drop testing.
