Classification: CPC H | IPC H

Claim 12:
13. A bonding method of package components, comprising:
operating a first holder to bring a first package component held by the first holder in contact with a second package component held by a second holder;
providing thermal energy to at least one of the first and second holders by a remote laser device or a remote infrared heater external to the first and second holders, to heat the first and second package components without dimension selectivity, wherein a waveguide configured to transmit the thermal energy extends into the at least one of the first and second holders from the remote laser device or the remote infrared heater; and
performing a selective heating on the first and second package components by using an induction heating system comprising an induction coil winding around the first holder, 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.
