Knownpcb on Instagram: "A microscopic metal filament. A major reliability risk. Tin whiskers are tiny conductive filaments that can grow from tin-plated surfaces in PCB assemblies. They may bridge adjacent pads and cause short circuits — sometimes long after production or shipment. What makes them especially challenging? • They grow unpredictably • They are often invisible during visual inspection • Failures can occur years later Tin whiskers are not simply a soldering defect. They are driven by
