Ensinger PEI
Epoxy Technology EPO-TEK® H44 Gold-Filled, Electrically Conductive Epoxy
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy, Electrically Conductive

Material Notes: Product Description: EPO-TEK® H44 is a single component, gold-filled, electrically conductive epoxy adhesive designed for hybrid microelectronic packaging.

Advantages & Application Notes:

  • High viscosity paste. Users should not expect the same creamy viscosity as silver-filled epoxies.
  • Design engineers need to be aware of longer lead times and shorter shelf-life than traditional silver-filled epoxies.
  • Suggested applications for hybrid/hermetic packaging: Die-attach and SMD attach instead of silver epoxy; avoiding silver migration inside sealed packages; medical and aerospace electronics and circuits.
  • Passes NASA low outgassing standard ASTM E595 with proper cure
