MIL-HDBK-780D
w/CHANGE 1
4.3 Approved SMD's. SMD's in use by DoD and industry are listed in MIL-HDBK-103.
4.3.1 SMD user. When a contractor or DoD component has a system application for an existing SMD, as listed in
MIL-HDBK-103, it is essential that the applicable MPCAG be informed accordingly.
4.3.2 Changes to SMD's. Utilizing user identification in accordance with MIL-HDBK-103, proposed changes or draft revisions are coordinated with all users of record. Changes are implemented in accordance with the provisions of MIL-PRF-38535. SMD's are maintained by the MPCAG. Approved revisions to SMD's are distributed by the MPCAG to all known users of record.
4.3.3 Nonconcurrence with proposed changes. User nonconcurrence with a proposed change to an SMD requires MPCAG resolution of the stated nonconcurrence. Unresolved nonconcurrence will require MPCAG action as appropriate, i.e., nonconcurrence reply, with technical justification, to the originator of the change proposal, new SMD's that address the diverse needs of the users involved, or advisory to user of need to generate new part acquisition documentation.
5. DETAILED GUIDANCE
5.1 Introduction. This section contains guidance for SMD's.
5.2 Drawing preparation. In coordination with and with the approval of the applicable Program Office, a MPCAG (see 3.3) will respond to a parts approval request with a drawing preparation package consisting of the following:
a. Drawing number
b. All known sources of supply
5.3 Initial drawing preparation.
5.3.1 Blank drawings. Blank drawings are not provided. Drawing format should be in conformance to figures 1 and
2.
5.3.2 SMD coordination. Preliminary draft coordinations with MPCAG and device manufacturers, comment resolution, certificate of compliance transmittal and final SMD preparation should be in conformance with figure 4.
5.3.3 Preliminary and final draft submittal. Preliminary draft will be typed and spaced in accordance with the drawing format (figures 1 and 2). Handwritten or pasted catalog excerpts are not acceptable. This preliminary draft may be on standard 8 1/2" x 11" paper. Once started by the contractor, it is expected that the process described herein will be completed. Preliminary drafts should be clearly marked preliminary draft on the first and last pages.
5.3.3.1 Preliminary draft construction. The preliminary draft is constructed through communication with the applicable MPCAG (see 6.2).
5.3.4 Maintenance. Maintenance of approved SMD's is the responsibility of the applicable MPCAG.
5.3.5 SMD content preparation. The following detail should be reviewed in conjunction with figure 5, especially regarding "boilerplate" location and content. The following detail reflects the current exclusive applicability of SMD's to Microcircuits.
5.3.5.1 Section 1, scope. 1. SCOPE should be as shown on figure 5 and conform to 4.2.2.1 as specified herein.
5.3.5.1.1 Scope. 1.1 Scope. should be as shown on figure 5.
5.3.5.1.2 PIN. The PIN should be structured in accordance with figure 5. The device type should be a two digit number, assigned sequentially, starting with 01, 02, 03, etc., depending upon how many parts are being included in the drawing.
