Fortunately, X-ray vision does reveal the secrets of board-level components:

Inductors reveal their wire coils.

Capacitors remain dark and elusive with all their wrapped dielectric layers.

Resistors are almost invisible, except for the solder that melts and creates a fillet on the edges of the resistor.

Invisible crystals are hidden beneath protective walls, but close to the processor to minimize latency and signal interference.

While the dots and swirls in the second image may look like single-celled organisms, they are not.

The swirls are the wire coils of the inductive charger. The large, dark blobs are solder mounts for a chip, and the wavy background pattern is the flash memory chip. More on that later...
