4-2 Removal and Replacement Preliminaries
4.1.2 Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following proper packaging and grounding precautions are necessary to
prevent damage to electric components and accessories.
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or
boxes.
Protect all electrostatic parts and assemblies with conductive or approved containers or
packaging.
Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
Place items on a grounded surface before removing them from their container.
Always be properly grounded when touching a sensitive component or assembly.
Avoid contact with pins, leads, or circuitry.
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
conductive foam.
4.1.3 Personal Grounding Methods
The method for grounding must include either a wrist strap or a foot strap at a grounded
workstation. When seated, wear a wrist strap connected to a grounded system. When standing, use
footstraps and a grounded floor mat.
