Components which can be destroyed by electrostatic discharge (ECB)
Generally, electronic boards should only be touched when absolutely necessary.
The human body must be electrically discharged before touching an electronic board. This can be
simply done by touching a conductive, grounded object directly beforehand (e.g. bare metal cubicle
components, socket outlet protective conductor contact.
Boards must not come into contact with highly-insulating materials - e.g. plastic foils, insulated
desktops, articles of clothing manufactured from man-made fibers.
Boards must only be placed on conductive surfaces.
When soldering, the soldering iron tip must be grounded.
Boards and components should only be stored and transported in conductive packaging (e.g.
metalized plastic boxes, metal containers).
If the packing material is not conductive, the boards must be wrapped with a conductive packing
material, e.g. conductive foam rubber or household aluminum foil.
The necessary ECB protective measures are clearly shown in the following diagram.
