CAUTION
Components which can be destroyed by electrostatic
discharge (ESD)
The optional boards contain electrostatic sensitive devices. These devices may be destroyed
by improper handling. Please pay attention to the following notes regarding the use of
electronic boards:
♦ Electronic boards should only be touched when absolutely necessary
♦ The human body must be electrically discharged before touching an electronic board
♦ 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
packaging material, e.g. conductive foam rubber or household aluminum foil.
The necessary ECB protective measures are clearly shown in the following diagram:
