Space and Military Avionics Applications Addendum to IPC-6012E, Qualification and Performance Specification for Rigid Printed Boards
|Publication Date:||1 April 2020|
This addendum provides requirements to be used in addition to, and in some cases, in place of, those published in IPC-6012E to ensure the reliability of printed boards that must survive the vibration, ground testing, and thermal cycling environments of space and military avionics.
When required by procurement documentation/drawin
The procurement documentation takes precedence over this Addendum and referenced standards. In the event of a conflict between this Addendum and the applicable documents cited herein, this Addendum takes precedence. Where referenced criteria of this addendum differ from the published IPC-6012E, this Addendum takes precedence.
Existing or Previously Approved Designs
This Addendum shall not constitute the sole cause for the redesign of previously approved designs. When drawings for existing or previously approved designs undergo revision, they should be reviewed and changes made that allow for compliance with the requirements of this Addendum.
Use of this Addendum
This addendum shall not be used as a stand-alone document.
Where criteria are not supplemented, the Class 3 requirements of IPC-6012E shall apply. Where IPC-6012E criteria are supplemented or new criteria are added by this Addendum, the clause is listed in IPC-6012ES, Table 1, Space and Military Avionics Applications Requirements, and the entire IPC-6012E clause and its associated Table 4-3 entry is replaced by this Addendum except as specifically noted.
The clauses modified by this Addendum do not include subordinate clauses unless specifically stated (i.e., changes made to 3.5 do not affect 3.5.1 unless 3.5.1 is also addressed in this Addendum.)
This addendum supersedes and replaces IPC-6012DS.
