Static prevention route
Ground
Grounding is implemented by the following methods:
1) The human body is grounded through the wrist strap: There are many types of wrist straps. It is recommended to use a wrist strap with a 1 megaohm resistor. The length of the cable should be left with a certain margin.
2) The human body is grounded through anti-static shoes and anti-static floor.
3) Workbench grounding: Use anti-static table mats for the surface of each workbench. Each mat has a 1 megaohm resistor on the string and is reliably connected to the anti-static ground.
4) Test instrument, tool holder, soldering iron grounding.
5) Work area Ground: Anti-static floor, floor mat or anti-static paint grounding. At present, our company uses anti-static paint to ground.
6) Anti-static transfer vehicles, boxes and racks should be grounded as much as possible.
7) Ground the anti-static chair.
Humidification:
The room temperature of the electrostatic safety zone is 23 ° C ± 3 ° C, and the relative humidity is 45-70% RH. The humidity in the protection zone is strictly prohibited to be less than 30%.
Protection
Anti-static overalls and static protective caps and gloves: used to shield the static electricity generated by the workers' clothing and hair during active walking and working.
Anti-static turnover box, anti-static component box: used for turnover, transportation and storage of batch products and components.
Anti-static shielding bag: used for packaging, transportation and storage of individual products and components, with a certain moisture-proof effect.
Anti-static strips and trays: used for storage and handling of a small number of components and products in the production workshop. It is forbidden to store or unpack packaging before use.
Explosion-proof human body electrostatic discharger
By installing an explosion-proof human body electrostatic discharge device, the static electricity carried in the body is released into the earth, thereby reducing the static electricity generated by the body belt. This is also an essential electrostatic protection device in the field of industrial chemicals.
