Anti-static requirements and precautions for electronic factories
1. Every worker who touches the circuit board should wear a corded electrostatic wrist
2. The manager who stretches and pulls up should wear a cordless electrostatic wrist
3. The technician should test the quality of the electrostatic wrist every two hours
4. For PCB boards, use electrostatic bags
5. For mobile vehicles (installed components or PCB boards), conductive soft rubber should be used for grounding
6. Mopping the floor twice a day
7. For the employee who is tested as 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. You can ask him to wash his hands. If he is high 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, please pay attention to the grounding. Because I have been to many factories, 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 the power supply are as high as this.
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. Pull on* so there is a damp cloth dragged on it
11. The employee's workbench should be anti-static and grounded
12. High static electricity in winter,
13. It is 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
Just add some thoughts:
1. All personnel entering the workshop must wear anti-static clothes and anti-static hats, and shoes generally have no metal parts.
2. Workers should operate according to SOP, and don't touch IC, ports and other ESD sensitive devices directly.
3. The anti-static ground must be kept well at all times.
By the way, I have a question to ask:
What is the anti-static principle of the cordless electrostatic wrist?
