This document describes materials that can be used for the fabrication of embedded passive capacitor devices within the finished printed circuit board substrate. For this document, embedded passive devices and the phrase embedded passives are conside red to be equivalent. It provides information on general designations and associated characteristics of embedded passive device (EPD) capacitor materials. The document shall be used as a qualification and conformance standard for these materials. Thi s document contains material designation, conformance (requirements), qualification (characterization) and quality assurance specifications. This document covers the requirements for dielectric, conductive, and insulating materials that are used with materials for the manufacture of printed circuit boards containing embedded passive capacitor functionality.
