Electrostatic charging 

Every person without a conductive connection to the electrical potential of his/her 

surroundings can be electrostatically charged. 
The figure below shows the maximum electrostatic charge that can build up on a person 

coming into contact with the materials indicated. These values correspond to IEC 801-2 

specifications.

Basic protective measures against electrostatic discharge 

 

Ensure good equipotential bonding:  

When handling electrostatic sensitive devices, ensure that your body, the workplace and 

packaging are grounded. This prevents electrostatic charge. 

 

Avoid direct contact: 

As a general rule, only touch electrostatic sensitive devices when this is unavoidable  

 

(e.g. during maintenance work). Handle the modules without touching any chip pins or 

PCB traces. In this way, the discharged energy can not affect the sensitive devices. 
Discharge your body before you start taking any measurements on a module. Do so by 

touching grounded metallic parts. Always use grounded measuring instruments.
