Abstract
Embodiments of the present invention relate to integral heating elements in solder pads for flip chip bonding. The integral heating elements are used to solder components together without exposing other locations and components in the assembly to potentially damaging temperatures. Embodiments of the invention may be used in manufacture of magnetic heads for EAMR hard disks to bond a laser sub-mount to an air-bearing slider without exposing magnetic head components to high temperatures.
