So, you’ve probably heard about flip chip IC technology, maybe in passing or maybe you’re knee-deep in a project that needs it. It’s this pretty neat way of putting computer chips onto circuit boards.

Gold-on-gold stud-bumps comprise a connection technique used in some microminiature flip-chip assemblies: (a) shows bumps on an IC; (b) is a close-up view. Flip-chip processes allow miniaturization of ...
