Guidelines for Handling Electrostatically-Sensitive Devices (ESD)
B.3 General Protective Measures Against Electrostatic Discharge
Damage
Ensure Sufficient Make sure that the personnel, working surfaces, and packaging are
Grounding
sufficiently grounded when handling electrostatically-sensitive devices.
You thus avoid electrostatic charging.
Avoid Direct
You should touch electrostatically-sensitive devices only if it is unavoidable
Contact
(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.
