CHAPTER 3MINIATURE AND MICROMINIATURE REPAIRPROCEDURESLEARNING OBJECTIVESUpon completion of this topic, the student will be able to:1. Explain the purpose of conformal coatings <strong>and</strong> the methods used for removal <strong>and</strong> replacement ofthese coatings.2. Explain the methods <strong>and</strong> practices for the removal <strong>and</strong> replacement of discrete components onprinted circuit boards.3. Identify types of damage to printed circuit boards, <strong>and</strong> describe the repair procedures for eachtype of repair.4. Describe the removal <strong>and</strong> replacement of the dual-in-line integrated circuit.5. Describe the removal <strong>and</strong> replacement of the TO-5 integrated circuit.6. Describe the removal <strong>and</strong> replacement of the flat-pack integrated circuit.7. Describe the types of damage to which many microelectronic components are susceptible <strong>and</strong>methods of preventing damage.8. Explain safety precautions as they relate to 2M repair.INTRODUCTIONAs you progress in your training as a technician, you will find that the skill <strong>and</strong> knowledge levelsrequired to maintain electronic systems become more dem<strong>and</strong>ing. The increased use of miniature <strong>and</strong>microminiature electronic circuits, circuit complexity, <strong>and</strong> new manufacturing techniques will make yourjob more challenging. To maintain <strong>and</strong> repair equipment effectively, you will have to duplicate withlimited facilities what was accomplished in the factory with extensive facilities. Printed circuit boards thatwere manufactured completely by machine will have to be repaired by h<strong>and</strong>.To meet the needs for repairing the full range of electronic equipment, you must be properly trained.You must be capable of performing high-quality, reliable repairs to the latest circuitry.MINIATURE AND MICROMINIATURE ELECTRONIC REPAIR PROCEDURESAs mentioned at the beginning of topic 2, 2M repair personnel must undergo specialized training.They are trained for a particular level of repair <strong>and</strong> must be certified at that level. Also, recertification isrequired to ensure the continued high-quality repair ability of these technicians.3-1
