Epoxy Technology EPO-TEK® H65-175MP Thermally Conductive Epoxy
Categories: Polymer; Thermoset; Epoxy; Epoxy, Thermally Conductive

Material Notes: Product Description: EPO-TEK® H65-175MP is a single component, alumina-filled epoxy for military hybrid die and component attach. It can also be used for semiconductor and high temperature ceramic and vacuum packaging.

Advantages & Application Notes:

  • Viscosity is suitable for automatic syringe dispensers, although it can be applied by screen printing or manual hand Operations.
  • Performs exceptionally well as a die-attach for small chips such as GaAs, LEDs and diodes, as well as SMDs.
  • Capable of resisting 260°C green reflow process, low outgassing in hermetic lid-seal processes near 300°C, and organic burn-in up to 150°C/1000 hours storage.
  • Certified to MIL-STD 883/Test Method 5011 –yields low levels of water extractable monovalent ions such as Chlorides.
  • Capable of JEDEC Level II die-attach packaging on die-paddles and lead-frames.
  • Widely used epoxy; popular choice for non-silver-filled die-attach epoxies; opto-packaging, hybrids, and many types of substrates including kovar, ceramic and BT.
  • Available in many different viscosity ranges
  • Can be used as non conductive staking epoxy, in conjunction with EPO-TEK® H35-175MP for attaching SMDs to the hybrid circuit.
