Re: A component inside PCB layers...

Multi-layer PCBs have power and ground planes - entire layers that are pretty much entirely metalled with copper. Quite some heat capacity there. This answers the question elsewhere about where the power comes from - directly underneath through a via.

In fact, embedding a device into the middle layers of a PCB is genius - likely to evade optical inspection.
