44 PCB007 MAGAZINE I OCTOBER 2019 take a look at these unique new words, includ- ing expanded definitions, and a quick-glance glossary. MIL-PRF-31032 Overview Terms 1. MIL-PRF-31032: The military specification for unpopulated PCBs. It is a combination of technical requirements from MIL-P-55110, MIL-P-50884, and IPC-6012; the management systems from ISO: 9001; and specific report- ing information about facility and process changes and general summaries of military shipments. 2. Defense Logistics Agency (DLA): The DLA in Columbus, Ohio, reviews the Technical Review Board's (TRB's) semiannual reports, adminis- ters web pages that contain the facilities quali- fication by material type and board complex- ity, maintains configuration management for military specifications, and audits each certi- fied facility every three to four years. 3. MIL-PRF-31032 Qualifying Activity: The qual- ifying activity for MIL-PRF-31032 is communi- cating with the DLA. 4. The Commercial and Government Entity (CAGE) Code: Is obtained by completing a System for Award Management Registration (SAM) and necessary to receive any type of payment from the federal government, and is a five-character ID number used extensively within the federal government assigned by the DoD's DLA. The CAGE Code supports a variety of mechanized systems throughout the government and pro- vides a standardized method of identifying a given legal entity at a specific location. Agen- cies may also use the code for a facility clear- ance or pre-award survey. There is no cost to obtain a CAGE Code. 5. Pre-validation: The manufacturer notifies the qualifying activity of its intent to pursue qualification to MIL-PRF-31032, starting a dia- logue between the two entities crucial to the success of the effort. 6. Validation: A qualifying activity (the or- ganizational element of the government that grants certifications, ergo DLA) will determine an organization's adequacy and compliance with the requirements listed in MIL-PRF-31032. The determination involves verification of the implemented quality management (QM) plan by a TRB, validation of the effectiveness of the implementation of the QM plan, and demon- strated the capability to produce printed board technology [1]. 7. Qualified Manufacturers Listing (QML): Is a detailed listing of the capabilities by material type that the manufacturer demonstrated dur- ing qualification testing. Customers using this list can quickly determine which manufactur- ers are capable of meeting their needs. 8. Specification Sheets: Military specifica- tions that supplement the base document and contain detailed performance requirements for specific printed board technologies. Tech - nologies are classified as different construc- tions or types of printed boards, such as rigid, flex, multilayer, high-speed, etc. This allows special requirements for different technolo - gies to be addressed as well as rapid imple- mentation of new technologies. This specifi- cation also allows the development of custom technology requirements where there is no supporting specification sheet, so customers can push the envelope for new technologi - cal advances without waiting for specification changes [1]. 9. Quality Management Plan (QMP): The man- ufacturer must maintain a documented and disciplined quality system that emphasizes process controls, defect prevention, and con- tinuous improvement. Manufacturers are en- couraged to develop a QM plan based on their existing process flow and quality system. 10. Self-validation: Self-validation is the man- ufacturer's means of determining compliance to MIL-PRF-31032 and the QM program. It is an internal audit to MIL-PRF-31032. Self-val- idation results must be reported to the TRB.
