This document describes materials that can be used for the fabrication of embedded passive resistor devices within the finished printed circuit board substrate. It provides information on general designations and associated characteristics of embedded passive device (EPD) resistor materials. The document shall be used as a qualification and conformance standard for designers and users when designing or constructing printed circuit boards containing these EPD materials. This document contains material designation, conformance (requirements), qualification (characterization) and quality assurance specifications. This document should be used in conjunction with both the IPC-2200 series design and the IPC-6010 series qualification and performance standards. 26 pages. Released April 2008.
