CHAPTER 8 PREVENTATIVE MAINTENANCE ON ELECTRONIC COMPONENTS TO 1-1-700 8.1 GENERAL. This chapter outlines corrosion inspection, removal, repair, and protection for electronic components and assemblies. When maintaining communications electronics equipment, it is important that care be given to selecting the proper tools and processes for preventing corrosion, removing corrosion and repairing corrosion-related damage. When treating corrosion, it is especially important to verify that all corrosion has been removed and all factors contributing to the corrosive environment have been eliminated. 8.2.5 Paragraph 8.7 provides instructions for removing corrosion from electronic equipment. Corrosion must be removed completely while minimizing damage to the surrounding areas. 8.2.6 Paragraph 8.8 provides guidance on selection and application of encapsulates and sealants. Encapsulates and sealants are the two chief ways of protecting electronics against moisture intrusion. 8.2.7 Paragraph 8.9 provides instructions and guidance with respect to specific situations and components common in ground communications electronics. 8.3 REPAIR SEQUENCE. This paragraph provides a step-by-step overview of the corrosion detection, removal, and repair processes. Figure 8-1. ANMST-TIV Corroded Exterior Plugs 8.2 DESCRIPTION. This chapter describes repair sequence, basic corrosion theory, inspection, corrosion removal, cleaning, surface treatments and handling of specific equipment components. The processes are described as follows: 8.2.1 Paragraph 8.3 provides a brief overview of a general electronics repair process. This process is appropriate for removing corrosion damage. 8.2.2 Paragraph 8.4 provides general corrosion theory and background specific to an electronics context. Properly addressing corroded electronic components requires a good understanding of the science of corrosion prevention and control. 8.2.3 Paragraph 8.5 provides guidance and instructions for inspecting electronic components for corrosion. The importance, in frequent comprehensive inspections in corrosion control, cannot be overstated. 8.2.4 Paragraph 8.6 provides instructions for cleaning electronic components. Electronic components must be clean in order to proceed with corrosion removal, repair, and prevention. 8.3.1 Inspect Component. The first step in repairing corrosion is inspecting the affected component. This is done to identify the presence, location, and extent of corrosion (or any other kind of damage). This process is described in detail in paragraph 8.5. 8.3.2 Clean Component and Remove Corrosion. Once the component has been inspected, all foreign material must be removed. This includes dirt, corrosion, products of corrosion, solder flux residue, and any other material that has been deposited on the electronics. Paragraph 8.6 gives detailed information regarding the cleaning process. Corrosion removal is covered in detail in paragraph 8.7. Once the component has been cleaned, briefly reinspect to ensure that all corrosion has been removed. 8.3.3 Identify the Conformal Coating. Before any damaged components can be removed and replaced, it is necessary to remove any conformal coating that may be present. There are five principal types of conformal coating defined by MIL- I-46058. • Acrylic Resin (Type AR) • Epoxy Resin (Type ER) • Silicone Resin (Type SR) • Polyurethane Resin (Type UR) • Paraxylylene (Type XY) 8-1
