Electrostatic Discharge (ESD) Module Practice Test

Ionizers in ESD control emit both positive and negative ions into the air to neutralize static charges on surfaces, people, and objects. By delivering ions to charged areas, the electrical potential on those surfaces is driven toward zero, which reduces the likelihood of a damaging electrostatic discharge when they come near grounded or other charged items. This is especially helpful for insulating materials and nonconductive packaging that don’t dissipate charge easily. Ionizers aren’t used to charge devices, they don’t moisturize the air, and they don’t seal packaging; their role is to balance and neutralize static charges.
