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 Statement of 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 QML program to
printed boards procured to non-QML documents such as MIL-P-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:
a. Self-validation: The TRB verifies the implemented QM plan.
b. Certification: The qualifying activity leads a team to validate the TRB's effectiveness in implementing their QM plan.
c. Qualification: The manufacturer demonstrates capability to produce a printed board technology.
d. 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 Qualified
Manufacturers List (QML)(see 6.4.26) listing. The appendices of this document are intended to aid the manufacturer in developing its
verification program. Appendices A and D are not mandatory. Appendices B, C, and E are mandatory. Appendix A is guidance that
describes a quality management approach using a TRB concept. Appendix B contains qualification procedure requirements. Appendix
C contains the conformance inspection requirements. Appendix D is guidance that describes techniques for test optimization (see
6.4.38). Appendix E provides statistical sampling and basic test and inspection requirements. Sectional associated specifications (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).
Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving
this document should be addressed to: Commander, Defense Electronics Supply Center ATTN: DESC-ELST,
