E.3 General Protective Measures Against Electrostatic Discharge
Damage
Ensure sufficient grounding
Make sure that the personnel, working surfaces and packaging are sufficiently
grounded when handling electrostatic sensitive devices. You thus avoid
electrostatic charging.
Avoid direct contact
You should touch electrostatic sensitive devices only if it is unavoidable
(for example, during maintenance work). Hold modules without touching the pins of
components or printed conductors. In this way, the discharged energy cannot
affect the sensitive devices.
If you have to carry out measurements on a module, you must discharge your
body before you start the measurement by touching grounded metallic parts. Use
grounded measuring devices only.
