Claim 0:
1. A bonding apparatus, comprising:
a first holder, configured to hold a first package component, and to be controlled for placing the first package component onto a second package component;
a second holder, configured to hold the second package component;
an induction heating system, comprising an induction coil winding around the first holder and configured to perform a selective heating on the first and second package components, wherein first electrical connectors at a bonding surface of the first package component as well as second electrical connectors at a bonding surface of the second package component are targeted by the selective heating and are bonded together as a result of the selective heating, whereas insulating elements in the first and second package components as well as other conductive elements in the first and second package components that are smaller in size than the first and second electrical connectors are not targeted by the selective heating; and
a remote laser device or a remote infrared heater, external to the first and second holders, and configured to provide thermal energy to at least one of the first and second holders through a wave guide extending into the at least one of the first and second holders.
