ESDS instructions and electromagnetic fields
An electrostatic-sensitive device (ESDS) is an individual component, integrated circuit, or
module that can be damaged by electrostatic fields or discharges.
ESDS regulations for handling boards and equipment:
When handling components that can be destroyed by electrostatic discharge, it must be
ensured that personnel, the workstation and packaging are well grounded!
Personnel in ESD zones with conductive floors may only touch electronic components if
they are
– grounded through an ESDS bracelet and
– wearing ESDS shoes or ESDS shoe grounding strips.
Electronic boards may only be touched when absolutely necessary.
Electronic boards may not be brought into contact with plastics and articles of clothing
manufactured from man-made fibers.
Electronic boards may only be placed on conductive surfaces (table with ESDS surface,
conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers).
Electronic boards may not be brought close to data terminals, monitors or television sets.
Minimum clearance to screens > 10 cm).
Measurements may only be carried-out on electronic boards and modules if
– the measuring instrument is grounded (e.g. via a protective conductor) or
– before making measurements with a potential-free measuring device, the measuring
head is briefly discharged (e.g. by touching an unpainted blank piece of metal on the
control cabinet).
