Gold-tin eutectic
WebBarrier Metal for Gold Tin Eutectic : The 80:20 Gold Tin (AuSn) eutectic is a favored material for attaching laser diodes to Aluminum Nitride (AlN) standoffs. This eutectic melts at the relatively low temperature of 278°C. … WebFeb 28, 1992 · This technique utilizes the unique property of the gold-tin alloy system in that the 232°C tin melting point is significantly lower than the 280 °C eutectic point and solid state interdiffusion. The bonding medium consists of Au Sn multilayer composite deposited directly on the object to be bonded.
