The Kulicke & Soffa 4124 Gold Ball is a gold ball bonder. The Kulicke & Soffa 4124 Gold Ball is a thermosonic ball bonder. The Kulicke & Soffa 4124 Gold Ball supports ball bonding and wedge bonding.[1][2][3][4][5]
What it is
How it works
A gold ball bonder forms conductive interconnections between an integrated circuit device and a package, printed circuit board, or other substrate. The process uses heat, ultrasonic energy, physical force, and time to create a first ball bond and a second wedge bond.[2]
The 4124 uses electronic flame-off to melt the end of the gold wire and form a ball at the wire tip. The 4124 uses a wire feed system with drag, kicker, and clamp functions to control wire movement during the bonding cycle. The 4124 uses a bonding head with ultrasonic transducer action and force control to place each bond at the selected site.[3]
Where it fits in the process flow
The 4124 is used after the workholder is set up and the device is positioned for bonding. The bonding operation follows ball formation and precedes completion of the bonded wire connection.[4]
Applications
The 4124 is used for gold ball bonding on integrated circuit chips and other devices that require electrical connectivity. The tool can bond devices mounted in standard packages and can also be used on printed circuit boards or other substrates.[2]
The 4124 is suited to thermosonic wire bonding workflows that use gold wire, a formed ball at the first bond, and a wedge bond at the second bond.[3][2]
