There comes a point in every technology's lifespan where, either by necessity or mandate (i.e., legislation), evolution must occur. We've seen this with the migration from through-hole to surface mount and, of course, the recent transition to Pb-free. One such technology that emerged on the scene more than a decade ago, but never quite got its legs, is embedded passives. Not that there wasn't interest - there was (and is). A relative few leading-edge firms invested in the technology and successfully employed it, but for commercial reasons (and in some instances, patent issues), it was not implemented. Now, however, it seems there is a renewed interest in the technology, largely due to miniaturization requirements. Like SMT many years ago, it appears embedded passives may be the industry's next leap of faith.
