Grounding the work area To prevent static damage at the work area: ● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ● Use static-dissipative mats, foot straps, or air ionizers to give added protection. ● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas. ● Disconnect power and input signals before inserting and removing connectors or test equipment ● Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces. ● Keep work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam. ● Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive. Recommended materials and equipment Materials and equipment that are recommended for use in preventing static electricity include: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm ± 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwear straps providing one-megohm ± 10% resistance ● Material handling packages ● Conductive plastic bags ● Conductive plastic tubes ● Conductive tote boxes ● Opaque shielding bags ● Transparent metallized shielding bags ● Transparent shielding tubes Tools and software requirements ● Torx T-15 screwdriver or flathead screwdriver ● Diagnostics software 54 Chapter 4 Removal and replacement procedures ENWW
