2.Workshop special anti-static chair anti-static principle
Grounding is the direct discharge of static electricity through a wire connection to the earth. This is the most direct measure of anti-static measures. For conductors, grounding methods are commonly used, such as artificial wrist straps with anti-static wrist straps and work surface grounding.
Grounding is implemented by the following methods:
1) The human body is grounded through the wrist strap.
2) The human body is grounded through anti-static shoes (or shoelaces) and anti-static floor.
3) The work surface is grounded.
4) Test equipment, tool holder, soldering iron grounding.
5) Anti-static floor and grounding mat.
6) Anti-static transfer vehicles, boxes, and racks should be grounded as much as possible.
7) Earth the anti-static chair or anti-static stool.

1.Why should we buy an anti-static chair or esd stool?
Anti-static chair is necessary for many companies. It uses ESD cushions, backrests and metal accessories and other structures to effectively discharge static electricity to the ground, with very good ESD electrostatic discharge performance, to meet the protection of clean room Static electricity and purification standards.
2.What are the test methods for anti-static chairs?
Point to point resistance and system resistance test:
Electrode structure used: column electrode diameter 63 mm ± 3 mm: electrode material is stainless steel or copper; electrode contact material conductive rubber, hardness 60 ± 10 (Shore A grade), thickness 6mm ± 1mm, the volume resistance is less than 500Ω: The electrode weight is 2.25 kg to 2.5 kg.
When testing point-to-point resistance, the product (material) should be placed on an insulating surface or placed in an actual state of use. Mesa surface resistance and volume resistance are greater than 1x10^13Ω, respectively, and their geometrical perimeter dimensions are larger than the measured material 10 cm. The distance between the electrodes is 300 mm. In the ground test, the distance between the electrodes is 900 mm to 1000 mm.
