Chemically Resistant adhesives
Epoxy Technology EPO-TEK® EM127 Electrically Conductive Epoxy
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy, Electrically Conductive

Material Notes: Product Description: EPO-TEK® EM127 is a single component, heat curable, electrically conductive epoxy adhesive for semiconductor IC and LED die attach applications.

Advantages & Application Notes:

  • Shiny silver appearance after cure is cosmetically desired in the LED industry.
  • One component chemistry provides ease of use and long pot life.
  • Low viscosity and high thixotropy ideal for high speed dotting and stamping processes.
  • High strength after MSL 1 moisture test.
  • Moderate Tg provides a robust and strong chemistry for small sized LEDs < 13 mil x 13 mil
  • Suggested Applications:
  • Semiconductor: die attach onto lead-frames
  • Electronics:
    • Electrically conductive adhesive (“ECA”)for PCB and level 3&4 connections to SMDs, discrete components and connectors.
    • Automotive proven ECA and COB die-attach epoxy.
  • Optics: LED die attach, ECA for LED and fiber optic industry
