Classification: CPC H | IPC H

Claim 16:
17. A bonding method of package components, comprising:
providing a first package component and a second package component, wherein first electrical connectors and a first dielectric layer are exposed at a bonding surface of the first package component, and second electrical connectors and a second dielectric layer are exposed at a bonding surface of the second package component;
operating a first holder to bring the first package component held by the first holder in contact with the second package component held by a second holder, wherein the first dielectric layer of the first package component is in contact with the second dielectric layer of the second package component;
heating the first and second package components without dimension selectivity by using a remote laser device or a remote infrared heater, such that the first dielectric layer is bonded with the second dielectric layer, wherein the remote laser device or the remote infrared heater is external to the first and second holders, and a wave guide extends into 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.
