Navy Electricity and Electronics Training Series - Historic Naval ...

Upon satisfactory completion of a 2M training course, a technician will be CERTIFIED to performrepairs. The CERTIFICATION is issued at the level at which the technician qualifies and specifies whattype of repairs the technician is permitted to perform. The two levels of qualification for technicians areMINIATURE COMPONENT REPAIR and MICROMINIATURE COMPONENT REPAIR. Miniaturecomponent repair is limited to discrete components and single- and double-sided printed circuit boards,including removal and installation of most integrated circuit devices. Microminiature component repairconsists of repairs to highly complex, densely packaged, multilayer printed circuit boards. Sophisticatedrepair equipment is used that may include a binocular microscope.To ensure that a technician is maintaining the required qualification level, periodic evaluations areconducted. By inspecting and evaluating the technician's work, certification teams ensure that theminimum standards for the technician's level of qualification are met. If the standards are met, thetechnician is recertified; if not, the certification is withheld pending retraining and requalification. Thisportion of the program ensures the high-quality, high-reliability repairs needed to meet operationalrequirements.Q1. Training requirements for (2M) repair personnel were developed under guidelines established bywhat organization?Q2. What agencies provide training, tools, equipment, and certification of the 2M system?Q3. To perform microminiature component repair, a 2M technician must be currently certified inwhat area?Q4. Multilayer printed circuit board repair is the responsibility of what 2M repair technician?LEVELS OF MAINTENANCEEffective maintenance and repair of microelectronic devices require one of three levels ofmaintenance. Level-of-repair designations called SOURCE, MAINTENANCE, and RECOVERABILITYCODES (SM&R) have been developed and are assigned by the Chief of Naval Material. These codes areD for DEPOT LEVEL, I for INTERMEDIATE LEVEL, and O for ORGANIZATIONAL LEVEL.DEPOT-LEVEL MAINTENANCE.SM&R Code D maintenance is the responsibility of maintenance activities designated by the systemscommand (NAVSEA, NAVAIR, NAVELEX). This code augments stocks of serviceable material. It alsosupports codes I and O activities by providing more extensive shop facilities and equipment and morehighly skilled technicians. Code D maintenance includes repair, modification, alteration, modernization,and overhaul as well as reclamation or reconstruction of parts, assemblies, subassemblies, andcomponents. Finally, it includes emergency manufacture of nonavailable parts. Code D maintenance alsoprovides technical assistance to user activities and to code I maintenance organizations. Code Dmaintenance is performed in shops, located in shipyards and shore-based facilities, including contractormaintenance organizations.INTERMEDIATE-LEVEL MAINTENANCESM&R code I maintenance, performed at mobile shops, tenders or shore-based repair facilities(SIMAS) provides direct support to user organizations. Code I maintenance includes calibration, repair,or replacement of damaged or unserviceable parts, components, or assemblies, and emergencymanufacture of nonavailable parts. It also provides technical assistance to ships and stations.2-2
