Anti-static wrist strap and foot strap
Anyone who handles ESDS devices should use anti-static wrist straps and foot straps. The role of wrist straps and foot straps is to quickly leak the static charge of the human body to the ground.
A general anti-static wrist strap is composed of a buckle, a belt and a ground connection wire. The straps, buckles and ground connection wires have good electrical contact. In order to ensure the safety of operators, there is usually a 1 megohm resistor in series on the ground connection line of the wrist strap to limit the current flowing through when the human body gets an electric shock to no more than 5 mA.
There are two types of wrist straps: one is used in the operating environment of general ESDS devices, and its resistance to ground in series is 1 megohm. The other is used for the operation of ESDS devices in special environments, and its resistance to ground in series is about 50 kilohms (see ETS).
When using the wrist strap, make sure that the wrist strap is in good contact with the human wrist, the ground connection wire, and the ground wire.
