S5-95F Guidelines for Handling Electrostatic Sensitive Devices (ESD)
Additional precautions for modules without housings
Note the following measures that have to be taken for modules that are not protected against
accidental contact:
• Touch electrostatical sensitive devices only
- if you wear a wristband complying with ESD specifications or
- if you use special ESD footwear or ground straps when walking on an ESD floor.
• Persons working on electronic devices should first discharge their bodies by touching grounded
metallic parts (e.g. bare metal parts of switchgear cabinets, water pipes, etc.).
• Protect the modules against contact with chargeable and highly insulating materials, such as
plastic foils, insulating table tops or clothes made of plastic fibres.
• Place electrostatic sensitive devices only on conductive surfaces:
- Tables with ESD surface
- Conductive ESD foam plastic (ESD foam plastic is mostly coloured black)
- ESD bags
• Avoid direct contact of electrostatic sensitive devices with visual display units, monitors or TV
sets (minimum distance to screen > 10 cm).
