XRF of particular elements and joint image of a printed circuit board (PCB) sample. Each color represents an element: Red – Cu, green – Sn, cyan – Nb, magenta – Pd, yellow – Br, blue – Ba, white – Ta). The image distortion is caused by the experimental alignment. The samples were measured in a back-scattering setup using a Timepix3-based device with a Si sensor. Show AdvaPIX models.
