High Speed Fabrication of Highly Uniform Metallic Spheres

An inexpensive method of generating highly uniform metallic balls from capillary stream break-up at ultra high speeds. Manufacture of solder balls (and other metallic balls), commonly used in the electronics industry, can be achieved using this method. Due to the nature of the droplet formation from the capillary stream break-up employed by this method, the resulting balls are highly uniform. The fabrication rate is on the order of tens of thousands of drops/sec, with no sieving or sorting necessary.
