Product Description
LOCTITE ECCOBOND UF 3812 reworkable epoxy underfill is designed for CSP, WLCSP and BGA applications. This low viscosity material is formulated to flow at room temperature with no additional preheating required. It cures quickly at moderate temperatures to minimize stress to other components. This material's high glass transition temperature and high fracture toughness enables excellent protection of solder joints during thermal cycling.
LOCTITE ECCOBOND UF 3812 exhibits stable electrical performance under thermal/humidity bias is compatible with most Pb-free solder and has excellent thermal cycling performance.
