ESD (7)

Please find out more about ESD.

What are consequences of ESD damage?

Best Case: after the detection of faulty components, it is replaced. This means a minimum delay in production.

Acceptable Condition: the identification of the components is done in the last card test card. Components are replaced. And this means delay in production.

A difficult situation: the identification of the faulty card on the device, the components on the card is identified, the component is replaced and the long delays experienced in the production ...

Unacceptable situation: identification of the faulty one in the field. Staff is sent to field to identify. Defective cards and components are identified, the customer's production stops. Reputaion is totally damaged.



What is static electricity?

The static electricity is on a specific surface (-) of excess electrons load or (+) the lack of electrons load. Static electricity means the increase of electric charge on the surface of objects. This electric charge remains on an object until it either flows into the ground, or loses its charge quickly by a discharge. Uneven load distribution and accumulation in this way creates a voltage difference between the surface may interfere with their other surface. This gives rise to the danger of sparks and harmful discharge.[...]


What should be done first so that ESD precautions could be effective?

For ESD precautions to be effective, everyone should have has the necessary training and awareness in the production area and must move in accordance with certain rules. Periodic ESD checks should be done. The values must be measured on a regular basis and should be confirmed in the manufacturing field. There must be a person or team responsible for the ESD precautions and ensure the sustainability of these controls.[...]


What is ESD Standard?

All environment related to ESD, IEC 61340-5-1 standard is available both in Europe and the world. IEC 61340-5-1 is the standard including test procedures and terms, approved ESD control, ESD products. IEC 61340-5-1 EPA (ESD protected area) should be used in areas with different ESD products also includes electrical properties.[...]


What is EPA?

EPA (Electrostatic Protected Area); are working areas the buildup of static electricity t is prevented for sensitive electronic components. Marked boundaries of a E.P.A. is clearly defined and will be attracted by everyone's attention.[...]
