Material Notes:

Product Description: EPO-TEK® H20E-LV is a two component, 100% solids silver-filled epoxy system designed specifically for chip bonding in microelectronic and optoelectronic applications. It is a low viscosity version of EPO-TEK® H20E, semiconductor die-attach epoxy.Advantages & Application Notes: Especially recommended for use in high speed chip bonding systems where very fast cures are desired. Suggested for JEDEC Level III and II for plastic IC packaging. Capable of resisting TC wire bonding temperatures in the range of 300°C to 400°C. Ease of use: apply by dispensing, screen printing, die-stamping or by hand. Especially suited for high power devices and high current flow. High power LEDs. Opto-electronic packaging material: LED, LCDs and fiber components. Information Provided by Epoxy Technology
