At present, most factories have recognized the harm of static electricity and have also protected it, but the results obtained are not very good. I have listed a few aspects, you can learn from them. See if your factory has this situation.
Person: 1. Single circuit wrist strap, unable to detect the contact impedance between wrist strap and human skin, resulting in ESD protection failure;
2. The wrist strap is not correct during the operation, and it cannot effectively discharge static electricity and cause the ESD protection to fail;
3. During the operation, Forgot to wear a wrist strap and directly touched the PCB board, which caused the ESD protection to fail.
4. The wrist strap is well worn during the operation, and the ESD protection is invalid due to poor static wire contact.
Machine: 1. The equipment plug row contacts leakage current, which cannot be effectively discharged and causes ESD protection failure;
2. Vibration in the production operation of the equipment causes the ESD protection to fail due to the electrostatic wire falling off or poor contact;
3. The ion elimination equipment is not turned on during the operation, and it cannot effectively neutralize the static electricity on the surface of the object to cause the ESD protection to fail;
4. The failure of the ion elimination equipment itself cannot effectively control the ion balance, resulting in the failure of ESD protection.
Methods: 1. Special personnel regularly check the spot, the first time may not be able to find problems, personnel time-consuming and laborious;
2. The inspection report needs to be filled in manually, which is prone to errors, the customer's "acceptance" is poor, and the staff is time-consuming and laborious.
3. The production and operation personnel do not pay attention to ESD, do not wear wristbands and cannot find the protection in time, resulting in the failure of ESD protection;
4. The production operators do not pay attention to ESD, do not turn on the ion elimination equipment, cannot find the problem in time, and cause the ESD protection to fail
5. ESD protection measures can not be digitized, visualized data, no data tracking analysis.
Environment: 1. The environmental temperature and humidity exceeding the standard can not be found in time, and can not form automatic intelligent and effective management with humidification and dehumidification equipment;
2. The environmental temperature and humidity data can not effectively form an effective data connection with the ESD protection system.
