When should Service Technicians wear an Electrostatic Discharge (ESD) wrist strap?

Wearing an Electrostatic Discharge (ESD) wrist strap during any repairs is crucial because it protects sensitive electronic components from static electricity that can cause damage. Static electricity can build up on a technician's body and be discharged when they touch electronic parts, potentially leading to component failure or reduced performance.

Using the ESD wrist strap helps to safely ground the technician, ensuring that there is no potential difference that can result in an electrostatic discharge. This is particularly important not just when handling specific components like motherboards, but throughout the entire repair process, including working on any internal hardware, testing components, or even simple repairs.

The need for an ESD strap is not limited to clean rooms, as static electricity can be a risk in various environments where electronics are handled. Therefore, the correct understanding is to wear an ESD wrist strap during any repairs to maintain the integrity of all electronic components involved.
