Static electricity is a serious threat to modern electronic devices. Even though electronic parts have been properly selected and applied, are on the preferred parts list, or have been procured in accordance with a qualification system such as MIL-PRF-38535, they can still be damaged by electrostatic discharge. For this reason, additional electrostatic discharge (ESD) controls are required. Therefore, it is essential that parts are selected with an eye toward their susceptibility to ESD damage, and that detailed precautions are taken to prevent ESD damage to electronic parts and equipment during their fabrication, storage and use.
Damaging electrostatic charges can easily be brought into assembly areas or into the parts storage area by people. They can also be generated in these areas during normal work movements.
