Tiny planets? Metal marbles? Bubble tea pearls? 🧋 Not quite. These are solder powder particles, magnified 2,000×. 🔬 Some of them are smaller than a human hair — but they help make reliable electronic connections possible. To check their quality, Heraeus experts create a cross-section of individual particles using a focused ion beam — almost like a nano-scalpel. This allows a scanning electron microscope (SEM) to reveal what is hidden inside: the microstructure, tiny pores, and inclusions. 🔎 These microscopic details matter. They can influence how reliably electronic components perform in everyday devices, mobility, industrial systems, and advanced electronics. 👉 Swipe to see how one of these tiny particles looks from the inside.
