The substrate, aluminum RF shield frame, SMT contacts, vias, and the two layers of the PCB are clearly distinguishable. Likewise resistors (nearly transparent) from capacitors (comparatively metal-heavy.)

Exposure: 100 sec. @ 32kV; 0.3mA @ 25cm. film: "Eco-30".

More interesting applications -- later.
