ATROX CD 590-HT2 is a thermosetting electrically conductive die attach paste designed for substrate-based and metal lead frame semiconductor packages, offering high thermal conductivity and reliable electrical performance. It is available in 5 or 10 cc syringes and cures via a ramp-soak profile at 125 °C for 30 minutes followed by 175 °C for 120 minutes,with optional peaks up to 200 °C. The cured material exhibits a bulk thermal conductivity of 10 W/mK, volume resistivity of 0.00004 Ohm-cm, glass transition temperature of 68 °C, and die shear strength ranging from 81 to 85 kg-f depending on substrate. It operates with CTE of 25 ppm below Tg and 166 ppm above Tg, maintains >24 hour pot life at 23 °C, and is formulated without added PFAS. Storage is recommended at -40 °C for shelf life exceeding six months.
