Study Notes
Electrostatic Discharge (ESD) Prevention
- ESD occurs when different electrical potentials build up between objects due to static charge.
- ESD can damage PC components.
- Static mats equalize static charges by providing a conductive surface that allows charge to dissipate.
- Grounding is essential for ESD Prevention, creating a single electrical potential between you, the case, and the mat.
- You need to establish a connection between the case, the mat, and yourself.
- Ground the case to the mat using an alligator clip.
- Ground yourself by connecting a wristband with a metal plate to your wrist.
- Always unplug the PC system before connecting grounding cables.
- Plugged-in power supplies can still provide a continuous current, even when the system is turned off.
- This can be hazardous as a faulty power supply could leak AC current to the system.
- A static mat and proper grounding procedures are essential for preventing ESD damage.
