  • Publication number: 20240404867
    Abstract: An apparatus can include a bonding head. The bonding head can include a bonding head body, a die chuck body, and lands. The bonding head body can be coupled to the die chuck. The lands can define zones. The lands and zones can be configured so that an outer zone can be under vacuum to hold a die while an inner zone is pressurized to cause the die to bow away from the bonding head. The bowed die has a relatively smoother curvature as compared to a die bent by bowing a die chuck that has pins, lands, or both. When the die contacts a substrate using the novel bonding head, the likelihood of trapping air and creating a void during a bonding operation is significantly reduced.
