An overview of the NCMS/StorageTek embedded decoupling capacitance project

The need for power-ground decoupling capacitance is nearly universal in electronic circuits. NCMS, NEMI and StorageTek have organized a project aimed at advancing the use of embedded capacitance technology for power supply decoupling. Embedding the capacitance in the PWB frees up space that can be used for other functions. The technology may also improve performance and reliability by reducing the number of solder joints and discrete capacitors, and the associated failure modes. Total system cost may also be lowered as a result of parts reduction and circuit integration. This presentation reviews the details of the project including project members, goals and objectives, test vehicle design, material considerations, electrical and qualification testing, modeling, deliverables, and timeline. This is a short-term project, intended to evaluate available materials, and to result in usable (designable, manufacturable, and cost-effective) embedded capacitance. The ultimate aim is to make this new technology a practical alternative in the very near future.
