  • Page 31: Esd Safety Precautions

    ESD Precautions Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. An electrical discharge is created to neutralize this difference, which can damage electronic com ponents and printed circuit boards. The following measures are generally suffi cient to neutralize this difference before contact is made to protect your equipment from ESD: Use a grounded wrist strap designed to prevent static discharge.
