PERFORMANCE SPECIFICATION
PRINTED CIRCUIT BOARD/PRINTED WIRING BOARD,
GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments and Agencies
of the Department of Defense.
1. SCOPE
1.1
Scope. This specification establishes the general performance requirements for printed circuit boards or
printed wiring boards (hereafter designated printed board) and the verification requirements for insuring that these
items meet the applicable performance requirements. Certification and qualification to this specification allows
manufacturer’s to apply the Qualified Manufacturers List (QML) program to printed boards procured to non-QML
documents such as MIL-PRF-55110 and MIL-P-50884 (see 6.3.4 and 6.5). The intent of this specification is to allow
the printed board manufacturer the flexibility to implement best commercial practices to the maximum extent possible
while still providing product that meets military performance needs (see 6.3.3). The principle concepts which allow
this flexibility are as follows:
a. The manufacturer forms an internal quality review system or organization referred to in this document as
the Technical Review Board (TRB) (see 6.4.37). The TRB is responsible for the implementation of a
quality management (QM) plan (see 6.4.31).
b. A relationship is established between the manufacturer and the qualifying activity.
The process to implement this specification can be summarized as follows:
c. Self-validation: The TRB verifies the implemented QM plan.
d. Certification: The qualifying activity leads a team to validate the TRB’s effectiveness in implementing their
QM plan.
e. Qualification: The manufacturer demonstrates capability to produce a printed board technology.
f. Maintenance: The TRB keeps the qualifying activity informed on the status of its QM program.
1.2
Description of this document. The main body of this document describes the requirements for obtaining a
QML (see 6.4.26) listing. The appendices of this document are intended to aid the manufacturer in developing its
verification program. Appendix A describes a quality management approach using a TRB concept. Appendix B
contains qualification procedure requirements. Appendix C contains the conformance inspection requirements.
Appendix D describes techniques for test optimization (see 6.4.38). Appendix E provides statistical sampling, basic
test, and inspection requirements. Sectional specification sheets (see 6.4.2) contain the performance requirements
and verification methods for printed boards by technology. Detailed requirements, specific characteristics, and other
provisions which are sensitive to the particular intended use of printed boards are to be specified in the printed board
procurement documentation (see 6.4.18).
