Thermally Conductive Epoxy

EPO-TEK® H65-175MP Advantages & Suggested Application Notes:● Viscosity is suitable for automatic syringe dispensers, although it can be applied byscreen printing or manual hand operations.
● Performs exceptionally well as a die-attach for small chips such as GaAs, LEDs anddiodes, as well as SMDs.
● Capable of resisting 260°C green reflow process, low outgassing in hermetic lid-sealprocesses 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 extractablemonovalent 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; optopackaging, hybrids, and many types of substrates including kovar, ceramic, and BT.
● Available in many different viscosity ranges – contact Technical Services attechserv@epotek.com for best recommendation.
● Can be used as non conductive staking epoxy, in conjunction with EPO-TEK® H35175MP for attaching SMDs to the hybrid circuit.
