Test equipments
Precaution in handling component
Common Abbreviations
Common symbol
- Static control test station is to test whether the waist strap is functioning well.
- Grounding test station is test whether the heel strap and static shoe grounded.
- The best method of handling ESD is to use an antistatic workbench, antistatic mat, artistic floor map, Earth Bounding point, Waist strap, heel strap, ESD coat & ESD chair.
- Static dissipative materials have electrical resistance between each other.
Bat- Battery
Pwr- Power
Xfr- Transformer
Gnd- Ground
Disc- Disconnect
Gen - Generator
Caution - Hazardous voltages are present. To reduce the risk of electric shock and danger to personal health, follow the instructions.
Caution - sensitive electronic devices do not ship or store near strong electrostatic, electromagnetic, magnetic or radioactive fields.
Attention – observe precautions for handling electrostatic sensitive devices.
What causes ESD
Conclusion
Preventing ESD
- ESDS can occur in our workplace and must not be underestimated.
- Knowing the safety precaution before handling and installing the electrical component.
- Always wear the necessary static accessories such as static wrist strap and heel strap to prevent ESDS.
- Ensure all electrical components are grounded to protect ourself and the component from static discharges.
- ESD is often generate by triboelectric when there is direct contact or separation with an another material.
- Triboelectric charge will occurs in our daily life.
- Handle any electronic component as a component sensitive to ESD.
- Do not touch a component unless you are in a ESD protected area and are properly grounded by one strap at least.
- Keep your work area free from food and beverages. Make sure it is clear of any static generating materials.
- Avoid any contact between components sensitive to ESD and insulating material.
- Store and transport ESD sensitive items in a static-shielding containers.

Precaution to observe when installing and removing ESD devices
- Ensure that the wrist strap & mats are working well.
- Use a specialize cleaner that is for static mats.
- Remove all nonessential plastic items from the workstation.
- Require personnel to wear footwear that is grounded.
- Wrist strap must be wore when they sit at a workbench.
- Each mat must be connected to the ground point.

- ESDS stands for ElectroStatics Discharge Sensitive device.
- ESD is a transfer of an electrostatic charge between bodies at different potentials and occurs with direct contact.
- It can transfer, or discharge, the electrical charge to component and will cause the component to be damage or no longer functioning.
