MOVING EMBEDDED PASSIVES FROM THE LAB TO THE FAB

摘要

What if you had to start putting integrated passives in your circuit boards today? What sorts of materials and processes do you have to choose from? Integrated passives for organic substrates are coming, not quickly and not all at once, but they will get here. We're all familiar with the various hurdles to implementing them: lack of design tools, an immature supply chain, uncertainty on cost effectiveness, questions over the best processes, yield issues, tolerance issues and required changes in business models. Covering all of these in any detail would require at least several issues of CircuiTree. In this article, I want to take the viewpoint of a company that manufactures circuit boards which, for whatever reason, wants to implement an integrated passive capability today. What options are available and how might they fit with a company's current capabilities?
