What is ESD caused by? | ESD is caused by the buildup of electrical charge (Static electricity) on one surface that is suddenly transferred to another surface when they touch |
Another name for static electricity or electricity at rest is? | Triboelectricity |
What type of ESD failure results in a total failure of the component or assembly? | Catastrophic |
What type of ESD failure has happened when the component appears to be operation normally but may experience prematurely failure | Latent |
What are the 3 primary control measures for the ESD program? | Workstation and personnel ground, handling precautions, and protective packaging |
What is the best method for controlling electrostatic discharge across an ESDs device? | Prevent the build-up of the charge. |
Before removing an ESDS circuit card from equipment, the technician will? | Ensure they are at the same potential as the equipment. |
