EPO-TEK® H20E is a highly reliable, silver-filled, two-component epoxy designed for high-performance electrical and thermal conductivity in microelectronic and optoelectronic packaging. This smooth, thixotropic paste is the industry choice for die attach, EMI shielding, and thermal management of LEDs and quartz crystals. With its exceptional die shear strength and NASA E595 low outgassing certification, the H20E is ideal for space-grade and high-vacuum applications where material stability is non-negotiable. Its unique 1:1 mix ratio and stable viscosity facilitate high-speed SMT printing or precision dispensing, while its “heat-cure only” chemistry ensures a long pot life for extended production shifts. H20E provides a durable, conductive path that resists thermal cycling and mechanical shock, making it an essential material for manufacturers of high-reliability power modules, radar systems, and advanced medical sensors.
