ESDS information and instructions
!
Caution
ElectroStatic Discharge Sensitive devices (ESDS) are individual components,
integrated circuits or modules which could be damaged as a result of electrostatic
fields or electrostatic discharge.
Handling ESDS boards:
When handling components which can be destroyed by electrostatic discharge,
it must be ensured that personnel, the workstation and packaging are well
grounded!
Electronic boards may only be touched by personnel in ESDS areas with
conductive flooring if
– they are grounded with an ESDS bracelet
– they are 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 >10 cm).
Measuring work may only be carried-out on the electronic boards, if
– the measuring unit is grounded (e.g. via a protective conductor) or
– when floating measuring equipment is used, the probe is briefly discharged
before making measurements (e.g. a bare-metal control housing is
touched).
