Ball Bonding Cycle

The ball bonding process is an interconnection technology linking the die to the lead within the micro-scheme.

The four main phases of the cycle are:

Ball shaped volume of gold created through melting of the wire protruding outside the capillary tipFree Air Ball squashed on the die, carrying the imprint of the capillaryShape of wire created by feeding through the capillary from the die to the leadWire squashed on the lead, carrying the imprint of the capillary tip

Each phase is the result of several operations performed by the capillary. These operations can be defined by eight stages that complete the bonding cycle.
