Araldite 7047 is a one-component, silver-filled epoxy adhesive said to combine high electrical and thermal conductivity. Is said to be a high purity, 100% solids system for void-free bonding of circuitry and ICs. Features a work life of up to four days at room temperature and reportedly cures in one hour at 165ºC (329ºF). Is compatible with Pb-free processing. Has aluminum/aluminum lap shear strength of 1300 psi and gold/gold die shear of 1700 psi at room temp. Volume resistivity at room temp. is <0.0002 ohm-cm. Has a Tg of 130ºC (266ºF) and CTE of 72 ppm/ºC.
