Part 5: The Technological Innovations in Multilayer Ceramic Chip Capacitors
In the early 1980s, a chip capacitor in the "3216" form factor (3.2 by 1.6 mm) had a capacitance of 0.1 µF, but that figure has reached 100 µF today—a thousand-fold increase. This matches electrolytic capacitors, which are characterized by high capacitance. A comparison at the same capacitance shows that miniaturization has also ...

Introduction to Ceramic Capacitors
Electro-plating of tin as the outermost layer gives an evenly thick layer also on edges and corners. But because of a perpendicular orientation of the tin crystals against the surface they are leaving access to oxidizing oxygen if the tin layer is too thin. Therefore it should rather be 10 than 3 μm thick (0.4 mils rather than 0.1 mil).
