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.
