Electrostatic Discharge (ESD) is a natural
occurrence in which electricity is passed through our body, or other
conductor, and discharges onto some object. For example, the shock we
feel when we touch a doorknob is an ESD. This natural occurrence is
becoming a very hot topic in the field of electronics assembly due to
the costly damage ESDs can cause to sensitive electronic equipment.

| What are the Resistivity
Ranges?
|
| Conductive:
Low resistance; carries electric charge quickly. < 105
Ω / square |
| Dissipative: The increased resistance
slows the transfer of charge from one point to another, offering
increased protection during ESD events. ≥105
and < 1012
Ω / square |
| Insulative: High resistance; does not
conduct electric charges well. ≥1012
Ω / square |
|
