Chemically Resistant adhesives

Epoxy Technology EPO-TEK® H61 Thermally Conductive Epoxy
Categories: Polymer; Thermoset; Epoxy; Epoxy, Thermally Conductive

Material Notes: Product Description: EPO-TEK® H61 is a single component, thermally conductive, electrically insulating, epoxy adhesive for semiconductor, hybrid IC, and electronic circuit assembly applications.

Advantages & Application Notes:

  • It is a thixotropic paste and a non-sagging adhesive. It is also useful for deposition methods like dispensing, printing, or hand held processes.
  • Suggested Applications:
    • Hybrid:
      • Staking SMDs onto the PCB for extra mechanical support; insulation layer between 2 contact pads of caps and resistors.
      • Heat sinking devices on ceramic PCB and PCB to external case; adhesion to Si, Au, kovar, Al-N, BT.
      • Reinforcing and extra mechanical support for wire bond integrity.
    • Electronics:
      • Bonding passive devices such as inductor coils, ferrites, motors, connectors, and various SMDs.
      • Adhesion to FR4 and common PCB substrates and housings.
  • Available in various viscosity alternatives and black color
