Abstract
An apparatus for bonding dice onto one or more substrates placed on a base comprises a first bond head and a second bond head. Each bond head incorporates a bonding tool which is configured for holding a die and both bond heads are driven by at least one linear motion actuator towards the substrate. The first and second bond heads are mounted on a stand and each comprises a locking mechanism which is operative to lock the bond head to the stand, and a compliant mechanism that is actuable to exert a bonding force on the bonding tool to bond each die to the substrate after the bond head has been locked to the stand.
