The anti-static wrist strap should be connected to the real ground wire.
The factory has clearly made anti-static grounding measures, which can not pass the test. What is the reason? A customer who is troubled by anti-static technology issues. He is sincerely willing to do anti-static grounding at the time, also for the customer to see. Did not think, there really is a problem.
At that time, for the convenience of work, a grounding wire jack was placed on the anti-static table mat. An electrostatic wrist strap can be inserted. The anti-static mat is laid on the production line. When the operator is working, except for wearing it. After wearing an anti-static clothing, anti-static shoes, and an anti-static mat, wear an anti-static wrist strap on your hand. Because the wrist strap is an effective way to ground the static discharge, connect the wrist strap to the desk mat. Going up, anyway, it is grounded.
In fact, the real standard is to connect the wrist strap to the ground. Because the anti-static table mat has a resistivity, if the anti-static wrist strap is directly grounded so that the static electricity is discharged well, then the anti-static mat is grounded, it has to cross the mat, and the operation is also placed on the mat. Some instruments are not a balance point with the ground, and they are not at a voltage value. Therefore, when grounding, the wrist strap must not be grounded on the grounding pad, and must be connected to the real grounding wire.
By explanation, the factory manager is willing to bear the added cost of doing static grounding. In the case of knowing the error, correcting it in time can create a good development prospect for the future of the factory.
