- ABOUT ELECTROSTATIC DISCHARGE (ESD)
- To a greater or lesser extent all contact between objects, every separation of one item from another, each sliding of one thing on another, causes a disturbance of electrical charge.
- When charge disturbance take place faster than charge redistribution, static charge accumulates.
- ESD occurs where charges of different electrostatic potentials meet.
- The flow of electrons is usually sudden and releases energy that can damage electrostatic sensitive devices (ESDs).
- This is referred to as tribo electric generations.
- Static charges of 30000 volts are not uncommon and can be generated by the simple act of walking across a floor, yet a discharge of only 10 volts can destroy a class 1 ESD sensitive device.
- A material that inhibits the generation of tribo electric charge is classified as anti-static.
- Anti-static material can be conductive (10^3-10^6 ohms/sq), static dissipative (10^7-10^9 ohms/sq), anti-static (10^10-10^12 ohms/sq) or even insulative (greater than 10^12 ohms/sq).
- Only conductive or static dissipative anti static material should be used in ESD protected areas.
