Electrostatic Discharge (ESD) Products
Electrostatic discharge (ESD) causes damage to electronic components or may influence their reliability. Walking on a synthetic carpet may charge the body with 35 000 volts . The sensitivity of an EPROM may be as low as 100 volts. Consequently serious risk prevails in handling electronic components. In the electronic industry it is practice to avoid such damage by appropriate earthing of equipment and personnel.
Metmeister provides a range of antistatic products to prevent electrostatic damage. The workstation and operator is connected to earth by way of 1M ohm resistors for protection.
Classification of Electrostatic Materials
1. Electrostatic conductive material with a surface resistivity greater than 104ohms/1.2m² and less than 103 ohms/1.2m². Temperature 20-70 degrees C
2. Electrostatic dissapative material with a surface resistivity greater or equal to 104 ohms/1.2m² and less than 1012ohms/1.2m²
3. Insulative material with a surface resistivity greater or equal to 1012ohms
