Anti-static requirements and precautions for electronic factories
1. Every worker who touches the circuit board should wear a corded electrostatic wrist
2. Managers who stretch and pull up should wear a cordless electrostatic wrist
3. The technician will test the quality of the electrostatic wrist every two hours
4. For PCB boards, use electrostatic bags
5. For mobile vehicles (components or PCB boards) should be grounded with conductive soft rubber
6. Mopping the floor twice a day
7. For the employee who tested high static electricity (no matter how good the static wrist is, it will not work for him). This is because his skin is too dry, so he can be asked to wash his hands. If his high is every time, he must be pulled up. The manager changed his position (especially chip, CD, VCD bald)
8. The electric batch, power supply, and instruments should be grounded, especially ferrochrome. For the 936 constant temperature ferrochrome, you should pay attention to grounding, because I have been to many factories, and many of them are not grounded (the ground wire is fake), and some 936 ferrochrome There is no grounding inside, which means that the ferrochrome is fake. At this time, the voltage can be measured above 70V. The electric batch and power supply are the same as this high.
9. For employees who are sitting next to the air conditioner or electric fan, they have a lot of static electricity. This is because the air conditioner is windy and the moisture is fast. At this time, you can request to adjust the distance between the workstation and the workstation.
10. It is best to have a wet cloth dragged on it
11. The employee's workbench should use an anti-static grounding buckle and ground it
12. High static electricity in winter
13. It's different when it rains
14. It's different when spotting at night
15. Add a damp cloth at the entrance of the workshop for people to step on
