Flip chip packages offer a very high level of input/output (I/O) density together with miniaturization, a combination that makes them very attractive for a growing number of applications. Still, though, designing the encapsulation process for a new flip chip can be a complex, costly and time-consuming experience. By using it with nondestructive micro-imaging, test boards can cut costs and complexity by rendering results acoustically visible.
