Recommended lead bond technique is thermocompression wedge bonding with 0.001” (25µm) diameter wire. The bond tool force shall be 35-38 gram. Bonding stage temperature shall be 230-240°C, heated tool (150-160°C) is recommended. Ultrasonic bonding is not recommended. 2.) The recommended die attach is an eutectic 80/20 Gold/Tin solder, using a stage temperature of 285-290°C. Maximum time at temperature is 1 minute. Use of forming gas (90% N2 , 10% H2 ) for best results. 3.) Bond on bond or stitch bond acceptable. 4.) Conductor over conductor acceptable. Conductors must not short.
