A Process to Produce Low Cost Solder Balls in Custom Sizes
Keywords: solder ball, manufacturing, process
Solder balls are a growing medium for device and system interconnect. They are available only in ceratin sizes forcing a designer to forego a more efficient design due to unavailability of solder balls in a desired size. This paper outlines a method to manufacture custom size balls with minimal tooling and equipment requirements. There are numerous methods to make solder balls. This method uses easily available existing equipment to produce custom size solder balls.
