MILPRF50884F
APPENDIX B
B.6.2.3 Certification of conformance. The printed wiring boards can be certified as being compliant to appendix B
of this document (MILPRF50884).
B.6.3 Benefits of the QML product assurance level. Printed wiring boards produced by QML manufacturers using
the provisions of this appendix in lieu of previous revisions would be compliant to this document
(MILP50884) when using the QML product assurance level with the added benefits as follows:
a.
The QML manufacturer can use pre-existing master drawing and production artwork without any
modifications needed (can use existing production masters test coupons and requires no additional or new
ones).
b.
The printed wiring boards, whether the QML option or the QPL option is used, will be the same.
c.
The level of quality will be the same or higher than the QPL product assurance level.
d.
When using the correct verification test (for the design), the cost should be the same or less due to
enhancements made to accept/reject criteria.
e.
Customers will be more confident that a QML manufacturer has demonstrated the capabilities to build its
design dues to its QML certification and qualification rather the generic standardized qualification test
vehicle of the QPL quality assurance level portion of previous revisions of this document.
B.6.4 Retention of qualification. The manufacturer need only to keep the qualifying activity apprised of its total
QML program, i.e., MILPRF31032 QML and this document's QML product assurance level. This means that the
manufacturer does not have to maintain two separate compliance programs, (i.e., no need for a QPL compliance
program for this document and a QML program for MILPRF31032).
B.6.5 Certification of conformance and acquisition traceability. The manufacturer can certify QML printed wiring
boards processed under their MILPRF31032 QML program as compliant to this document. The certificate of
compliance should reference the QML product assurance level to differentiate the compliant product from printed
wiring boards verified using the QPL product assurance level offered in this document.
B.6.6 Past specification revisions (see appendix D for more details). Printed wiring boards procured to this
document meets and exceeds all quality and reliability requirements of previous revisions of MILP50884.
