ESD Notes
Electrostatic sensitive devices (ESD) are single components, integrated circuits or devices
that can be damaged by electrostatic fields or electrostatic discharges.
Regulations for the ESD handling:
During the handling of electronic components, pay attention to the grounding of the person,
workplace and packaging!
Electronic components may be touched by persons only when
• these persons are grounded using an ESD bracelet, or
• these persons in ESD areas with a conducting floor wear ESD shoes or ESD grounding
Electronic components should be touched only when this is unavoidable. The touching is
permitted only on the front panel or on the circuit board edge.
Electronic components must not be brought into contact with plastics or clothing made of
artificial fibers.
Electronic components may only be placed on conducting surfaces (table with ESD coating,
conducting ESD foamed material, ESD packing bag, ESD transport container).
Electronic components may not be placed near display units, monitors or televisions
(minimum distance from the screen > 10 cm).
Measurements must only be taken on boards when the measuring instrument is grounded
(via protective conductors, for example) or the measuring probe is briefly discharged before
measurements are taken with an isolated measuring device (for example, touching a bare
metal housing).
