Micro-sections of circuit boards

Micro-Sections Of Circuit Boards Node Full Image 2

Space in Images – 2014 – 11 – Micro-sections of circuit boards.

Embedded within these resin discs are vital clues to determine whether future space missions will fail or thrive.
These are microsections taken from printed circuit boards (PCBs), being considered for use by coming ESA projects. Such boards are key building blocks of space missions.

As the electric, electronic and electromagnetic components hosted on PCBs are increasingly miniaturised, satellites are becoming much smarter and more capable – provided the boards function as intended.

ESA’s Materials and Electrical Components Laboratory – based at the ESTEC technical centre in Noordwijk, the Netherlands – has the task of checking if the performance and workmanship of candidate boards and assemblies meet rigorous space-quality standards.

Any defect in the PCBs, or in the soldering process used to attach components to the boards, could impair satellites, or even lead to the total loss of a mission.

For its role as technical gatekeeper, the Lab is equipped with powerful diagnostic tools, including optical and scanning electron microscopes capable of hundred-thousand-scale magnification.

The microsections are cast inside resin to make them easier to prepare and inspect on a microscope, in some cases with dye added to help detect defects and reveal any materials and processes underperformance.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
