HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
•
Persons at a work bench should be earthed via a wrist strap.
•
Equipment cases should be earthed.
•
All tools used during assembly, including soldering tools and solder baths, must be earthed.
•
MOS devices should be packed for dispatch in antistatic/conductive containers.
