MIL-HDBK-780D
w/CHANGE 1
3. DEFINITIONS
3.1 Standard microcircuit drawing (SMD). SMD's depict the Government's requirements for an existing commercial item, tested for a military application, disclosing applicable configuration, envelope dimensions, mounting and mating dimensions, interface dimensional characteristics, specified performance requirements, and inspection and acceptance test requirements as appropriate for a military environment.
3.2 General specification. A general specification is prepared in the six-section format and covers requirements and test procedures that are common to a group of parts, materials, or equipments. It is used with either associated device specifications, specification sheets or SMD's (not a mixture); e.g., MIL-PRF-38534 or MIL-PRF-38535 for microcircuits.
3.3 Military Parts Control Advisory Group (MPCAG). A DoD organization which provides advice to the military departments and military contractors on the selection of parts in assigned commodity classes, and collects data on nonstandard parts for developing and updating military specifications and standards.
4. GENERAL GUIDANCE
4.1 Introduction. This section provides general guidelines regarding contents, organization, and paragraphing applicable to the preparation of SMD's. SMD's should be in a standard drawing format in accordance with the guidance contained herein (see figures 1 and 2).
4.2 Sectional arrangement of an SMD. An SMD contains six sections, titled and numbered as shown below. SMD's should be in standard drawing format in accordance with ASME Y14.100 (see figures 1 and 2).

6. NOTES
4.2.1 Subject matter. Subject matter should be kept within the scope of the sections so that the same requirements or information will always appear in the same section of every SMD. If there is no information pertinent to a section, the following should appear below the section heading:
"This section is not applicable to this drawing".
4.2.2 Section 1.
4.2.2.1 Scope. The scope should repeat the item name and its modifiers, and provide a clear, concise abstract of the coverage of the SMD. This brief statement is the beginning paragraph. The scope should not contain requirements that should be part of section 3. Figures are not included in the scope.
4.2.2.2 Part or Identifying Number (PIN). Section 1 includes a paragraph entitled "PIN" which describes how the
SMD PIN is constructed (see 5.3.5.1.2).
