This document describes materials that can be used for the
fabrication of embedded resistor devices within the finished
printed circuit board substrate. It provides information on
general classifications and associated characteristics of
embedded passive device (EPD) materials. This document
shall be used as a qualification and conformance standard
for designers and users when designing or constructing
printed circuit boards containing EPD materials. For this
document, embedded passive devices and the phrase
embedded passives are considered to be equivalent.
This document contains embedded resistor material designation,
conformance (requirements), qualification (characterization)
and quality assurance specifications. IPC-4811
should be used in conjunction with IPC-2000 series design
standards and IPC-6010 series qualification and performance
standards.
Embedded capacitor material designation, conformance
(requirements), qualification (characterization) and quality
assurance specifications are contained in IPC-4821.
