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:

FG CPLD 2x

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″.

Please prove that you are human:

117 xor 75 = ?

What is the serial baud rate of the FG device ?
