MIL-PRF-55110 Printed Wiring Board, Rigid, General Specification ForThis specification establishes the performance and qualification requirements for rigid single??sided, double??sided, and multilayered printed wiring boards with or without plated through holes \(see 6.1\). Verification is accomplished through the use of one of two methods of product assurance \(QPL or QPL/QML\). Detail requirements, specific characteristics, and other provisions which are sensitive to the particular intended use are specified in the applicable master drawing.

APPENDIX D

D.3.5

D.3.5 Printed wiring board types. The printed board types shall be as defined in IPC-D-275 or IPC-2222. Printed

board types 4, 5, and 6 described by IPC-D-275 or IPC-2222 were included in type 3 of MIL-STD-275.

D.4. SUPERSESSION

D.4.1

D.4.1 Superseded specifications. Appendix A of this document includes the essential requirements of the previous

revision and can be used to supersede the specifications listed in 6.4.4.

D.4.1.1

D.4.1.1 Reference to superseded specifications. All the requirements of this document (MIL-PRF-55110G) can be

interchangeable with those of MIL-P-55110. Therefore, existing procurement documents (master drawings or OEM

documents) referencing MIL-P-55110 need not be revised, updated, or changed to make reference to

MIL-PRF-55110 in order for this document to be used.

D.4.2

D.4.2 Superseded guidelines and standards. The following design standards have been superseded by IPC-2221

or IPC-D-275 for all types and classes of printed wiring boards:

MIL-STD-275D, dated 26 April 1978.

MIL-STD-275D with notice 1, dated 19 January 1979.

MIL-STD-275D with notice 2, dated 10 October 1979.

MIL-STD-275D with notice 3, dated 5 October 1980.

MIL-P-55110C with notice 4, dated 28 May 1982.

MIL-P-55110C with notice 5, dated 7 February 1984.

MIL-STD-275E, dated 31 December 1984.

MIL-STD-275E with notice 1, dated 8 July 1986.

IPD-D-275, dated September 1991.

IPC-D-275 with amendment 1, dated April 1996.

IPC-2221A, dated May 2003.

IPC-2221 with amendment 1, dated January 2000.

IPC-2221, dated February 1998.

D.4.2.1

D.4.2.1 Estimation of design standard used. When no design standard is listed on the master drawing, either the

design activity or printed board manufacturer, should be contacted to ascertain which design standard should be used

to verify the design parameters during group A or group B inspection.

D.4.2.2

D.4.2.2 Retooling. Printed wiring boards that were designed using superseded Department of Defense design

standards do not require conversion to IPC-2221 or IPC-D-275.

D.4.3

D.4.3 Testing.

D.4.3.1

D.4.3.1 Group A testing. Group A testing should be performed to the specific revision, and amendment if

applicable, called out by the acquisition documents. For example, if printed wiring boards are produced to

MIL-P-55110D with amendment 1, MIL-P-55110D with amendment 3, and MIL-P-55110E, a manufacturer would be

expected to perform group A testing, for the applicable lot, to the requirements of the revision specified. In those

three different revisions (D with amendment 1, D with amendment 3, and E) a requirement for an acceptability criteria

or test procedure may be the exact same, it might be slightly different, it may be significantly different, or there may

not even be a requirement. Retention of qualification summaries for group A should list the lots produced, grouped by

revision, and when applicable, revision with specific amendment.
