X-Ray Microscopy Kindergarten.
This article is a continuation of "PCB Radiography Kindergarten, Continued.".
The radiography system is equipped with a "microfocus" tube, and its beam has a 30 degree spread cone. So we can get a look at that very same FG TRNG XC9572 CPLD seen earlier, but with 2x magnification:

This time, we can clearly distinguish the gold bonding wires which connect the silicon die to the pins.
Unfortunately, it is not possible to take a shot of the die surface using this type of instrument... (or is it..?)
Exposure: 85 sec. @ 34kV; 0.3mA + 2x beam spread; film: "Eco-30".
