Indium Spheres

Spheres are the form of indium I use the most for testing solder wetting properties, because they have a precise volume. (As opposed to shot, which does not have as tightly controlled size or sphericity restrictions.) Spheres are commonly used as interconnections for flip-chip attachment and BGA devices. We also provide spheres alloyed with other elements such as silver. Alloying indium generally hardens the material and decreases its ability to cold weld.
