How to choose high quality anti-static wrist strap manufacturers
The anti-static wrist strap is a kind of wristband that is worn by workers on the wrist to discharge static electricity. It is often used in the production line of electronic products. Divided into corded and cordless, we don't say cordless today, because the electrostatic discharge function of cordless wrist straps is much worse than that of corded ones. Anti-static wrist strap (wired) consists of elastic band, movable snap button, spring cord, protective resistor and plug or chuck. The inner layer of the elastic band is woven with antistatic yarn, and the outer layer is woven with ordinary yarn. When the worker wears the wrist strap on the wrist, buckles the button, and the other end of the plug or the chuck is grounded, so that the static electricity of the body can be effectively released.
After using the anti-static wrist strap for a period of time, the wristband in the cheap wristband will break off and the anti-static effect will not be achieved. It is not known that it has failed, and it has caused electrostatic accidents after touching static sensitive parts. However, the anti-static wrist straps produced by regular manufacturers are not likely to be in this situation. They are subjected to strict rigorous heavy weight bending tests, and the product process, quality and process are strictly monitored and guaranteed. The product can meet the specified number of bends and can guarantee the service life. This is why some foreign companies have designated the use of big foreign brands wristbands.
When a person accidentally touches a high static power source, causing a large amount of static charge to be instantaneously introduced, the antistatic wrist strap can provide ion neutralization (which is a Corona discharge effect) by the external air water molecules of the screw when the ion is not neutralized. The static electricity is effectively eliminated, and the ultimate goal of electrostatic discharge (static voltage balance) is achieved. However, some cheap anti-static wrist straps produced in China may not neutralize static electricity in time. For example, the position of the snap button may sometimes be less tight after several times of use, when the worker is in operation. People continue to move, the static electricity on the body is constantly generated. At the same time, the anti-static wrist strap is sometimes fully fastened, sometimes not fully fastened. It is likely that the static electricity of the body will penetrate the chip within 0.1 seconds, causing an electrostatic accident. Any "spirits".
The current status of domestic anti-static wrist strap manufacturers is low quality and low price. So that the standard is only for the performance of the product, there is no standard for quality. As long as the product can reach 1MΩ resistance is acceptable. No standards or warranties are available for the service life. Therefore, if the product itself has a high requirement for static electricity, in order to prevent the occurrence of static electricity accidents, the principles of anti-static equipment and tools must not be cheap, otherwise the damage caused by electrostatic accidents will be even greater.
