Material Notes:

Product Description: EPO-TEK® H24 is a two component, electrically and thermally conductive epoxy adhesive designed for semiconductor die attach and hybrid micro-electronics assembly.Advantages & Application Notes: Low density silver-filled epoxy is ideal for ultrasound and acoustical applications of electronics.Extended pot-life allows for mass production and low waste.Suggested Applications:Hybrid Micro-electronics: SMD and die attach on Au pads and ceramic substrates. Single step curing method of die and SMDs.Electronics: compatible with piezo technologies for ultrasound circuits found in medical, industrial, and petrochemical industries.Scientific / Life Sciences: geo-thermal, geo-seismic, infra-sound, as well as acoustical-optical circuits for interferometers and lasers.Optical: bright and shiny silver flake is advantageous for LED die-attach.A smooth and creamy paste allows for automated or hand dispensing, pin transfer, or screen printing application methods of manufacture.Information Provided by Epoxy Technology
