Ultrathin Discrete Capacitors for Emerging Embedded Technology
Written By: Radim Uher | Tomas Zednicek
Abstract:
Passive components can represent as much as 70% of PCB footprint in today’s electronic systems. The development of a suitable technology whereby integrated passive components are embedded into the PCB body has been one of the key trends in downsizing for more than a decade. Latest achievements have allowed the implementation of this ‘embedding technology’ into pre-production and even mass production. The next step requires the involvement of the complete supply chain, including traditional passive component manufacturers. This paper will present the state of the art in the development of ultrathin discrete capacitor technology and discuss the challenges of overcoming mechanical, electrical and thermo-mechanical issues specific to the embedding processes. Reliability and component life considerations will be also shown and discussed.
