Foreword

ESDS notices

Caution

ElectroStatic Discharge Sensitive Devices (ESDS) are individual components,

integrated circuits, or modules that can be damaged by electrostatic fields or

discharges.

Regulations for handling ESDS components:

When handling electronic components, you must ensure that the person

carrying out the work, the work place, and packaging are properly grounded.

Personnel in ESDS areas with conductive flooring may only handle electronic

components if:

– They are grounded with an ESDS wrist band

– They are wearing ESDS shoes or ESDS shoe grounding straps

Electronic boards should only be touched if absolutely necessary. They must

only be handled on the front panel or, in the case of printed circuit boards, at

the edge.

Electronic boards must not come into contact with plastics or items of clothing

containing synthetic fibers.

Boards must only be placed on conductive surfaces (work surfaces with ESDS

surface, conductive ESDS foam, ESDS packing bag, ESDS transport

container).

Electronic modules must be kept at a distance from data display equipment,

monitors, and televisions (minimum distance from screen: >10 cm).

Measurements must only be taken on boards when:

– The measuring device is grounded (with a protective conductor, for

example).

– The measuring head has been temporarily discharged before

measurements are taken on a floating measuring device (e.g. touching a

bare metal controller housing).
