ESD Training


What is Electrostatic Discharge (ESD) ?

It's the sudden transfer (Discharge) of electricity from One Object To Another. ESD is commolny known as "static electricity."

Some examples are :

  • Lightning
  • The "shock" you sometimes feel in the winter when you walk across a carpet and touch a doorknob.
  • The Sparks you sometimes see when undressing in the dark.

ESD seems harmless, but it can severely damage electronic components and assemblies.


Why should I learn about ESD control ?

Because ESD is one of the most serious problems facing the electronics industry today.

ESD can result in :

  • Products Failures
  • More rejects - higher costs
  • Unhappy customers.

Everyone benefits when ESD is controlled!
Product quality can improve and costs can be kept down. This can increase customer satisfaction - and sales.
You can help prevent ESD!


What cause ESD ?

Every object can hold an electrical charge.

This Charge Is Either: Positive (+) Or Negative (-).

When two objects rub or slide together or are separated, they become charged. When two objects with different charges come close together, electrons can suddenly flow from one object to the other.

This sudden flow of electrons is ESD!




ESD is most often caused by people !

  • Your body easily becomes charged when you move.
  • Your skin, hair and body can store relatively large amount of static electricity.
  • You can transfer (discharge) this electrical charge to components or assemblies - causing ESD damage.




ESD is also increased by :

  • Low relative humidity (dry air).
  • The use of synthetics, plastics and insulators in work area.
  • Your body easily becomes charged when you move.
  • Bending, walking shifting or rolling in a chair, on waxed floors or synthetic carpets.


How is ESD able to damage a component or assembly ?

Even a tiny transfer of electrical charge - one that you can't see, hear or feel - is as damaging as a bolt of lightning to some components and assemblies.
Anyone who works with electronic components or assemblies can cause ESD damage.



Today's components and assemblies are more efficient and smaller then ever before. They are also often much more delicate and sensitive to static electricity !
