How to use anti-static wrist strap correctly
The anti-static wrist strap electrostatic ring is a device that is worn on the human body's wrist to discharge the accumulated electrostatic charge of the human body. It is divided into wired type and wireless type, with metal ring and elastic conductive wire mixed ring. Among them, the buckle adjustment of the wired anti-static wrist strap can effectively protect the zero-resistance parts from the interference of static electricity and discharge the static electricity of the human body. It is composed of anti-static elastic band, movable snap buckle, spring cord, protective resistor and chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn.
Tools/Materials
Anti-static wrist strap
Electrostatic grounding socket (a qualified electrostatic grounding system)
Method/Step
1. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the earth through the wrist strap and the grounding wire. When in use, the wrist strap is in contact with the skin, and the grounding wire is directly grounded, so that it can exert its maximum effect. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 seconds. The grounded wrist strap is the most basic anti-static equipment and the most commonly used.
2. Make sure that the metal buckle of the anti-static wrist strap is in full contact with the skin, and the other end of the wrist strap is correctly connected to the grounding jack of the device.
3. However, due to the influence of various products or environmental factors during the use of products at the production site, most of the products did not achieve the expected use effect, so a large number of extensibility problems occurred.
1. The anti-static wrist strap has been tested by the equipment outside the workshop, but what is the real-time working status of the anti-static wrist strap during the use of the product?
2. How to prevent the improper wearing of the anti-static wrist strap by the operator from causing failure of electrostatic protection;
3. Relevant departments are mere formalities in the work of electrostatic protection, and perfunctory to the test results of anti-static wristbands, resulting in an increase in product defect rates;
4. Due to the unsure of the operator’s on-site electrostatic protection situation, the company blindly adds electrostatic protection products, resulting in an increase in personnel and company costs:
5. Due to the uncertainty of the operator’s on-site electrostatic protection situation, the operator was required to check the anti-static wrist strap every other time during the work period, which caused a loss of manpower.
