CHAPTER 2
MINIATURE/MICROMINIATURE (2M) REPAIR
PROGRAM AND HIGH-RELIABILITY SOLDERING
LEARNING OBJECTIVES
Upon completion of this topic, the student will be able to:
1. State the purpose and need for training and certification of 2M repair technicians.
2. Explain the maintenance levels at which maintenance is performed.
3. Identify the specialized and general test equipment used in fault isolation.
4. Recognize the specialized types of tools used and the importance of repair facilities.
5. Explain the principles of high-reliability soldering.
INTRODUCTION
As mentioned in topic 1, advances in the field of microelectronics are impressive. With every step
forward in production development, a corresponding step forward must be made in maintenance and
repair techniques.
This topic will teach you how the Navy is coping with the new technology and how personnel are
trained to carry out the maintenance and repair of complex equipment. The program discussed in this
topic is up to date at this time, but as industry advances, so must the capabilities of the technician.
MINIATURE AND MICROMINIATURE (2M) ELECTRONIC REPAIR PROGRAM
Training requirements for miniature and microminiature repair personnel were developed under
guidelines established by the Chief of Naval Operations. The Naval Sea Systems Command (NAVSEA)
developed a program which provides for the proper training in miniature and microminiature repair. This
program, NAVSEA Miniature/Microminiature (2M) Electronic Repair, authorizes and provides proper
tools and equipment and establishes a personnel certification program to maintain quality repair.
The Naval Air Systems Command has developed a similar program specifically for the aviation
community. The two programs are patterned after the National Aeronautics and Space Administration
(NASA) high-reliability soldering studies and have few differences other than the administrative chain of
command. For purposes of this topic, we will use the NAVSEA manual for reference.
The 2M program covers all phases of miniature and microminiature repair. It establishes the training
curriculum for repair personnel, outlines standards of workmanship, and provides guidelines for specific
repairs to equipment, including the types of tools to use. This part of the program ensures high-reliability
repairs by qualified technicians.
