Categories: Polymer; Thermoset; Epoxy

Material Notes: Appearance: Tan

Cure: Heat Cure

Product Benefits:

  • One component
  • Fast cure at low temperatures
  • Low cure temperature
  • Void-free underfill
  • Low CTE
  • Non-anhydride curing chemistry
  • Long pot life
Application: Underfill

Typical Package Application: Flip chip devices

LOCTITE ECCOBOND E 1172 A is formulated for use with very fine area array devices where SMT transparent processing is critical. This material can underfill devices with 25 micron geometries. LOCTITE ECCOBOND E 1172 A provides a uniform and void-free encapsulant underfill, maximizing the device's temperature cycling capability, distributing stress away from solder connects.
