B.3 Basic measures for protection against discharge of static electricity
Ensure sufficient grounding
When working with electrostatic sensitive devices, make sure that the you, your workstation,
and the packaging are properly grounded. This prevents the accumulation of static
electricity.
Avoid direct contact
You should only touch ESD components if unavoidable (for example, during maintenance
work). When you touch modules, make sure that you do not touch either the pins on the
modules or the printed conductors. If you follow these instructions, electrostatic discharge
cannot reach or damage sensitive components.
If you have to take measurements on a module, make sure that you first discharge any static
If you have to take measurements on a module, make sure that you first discharge any static
that may have accumulated in your body. To do this, touch a grounded metal object. Only
use grounded measuring instruments.
