Description / Abstract:
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.
