Is the wireless wristband useful for electronics companies?
Anti-static wrist straps are divided into wired wrist straps and wireless wrist straps. Relatively speaking, wireless wrist straps are more convenient because they are less restrained. However, in fact, the factory chooses more wired wrist straps, although sometimes it is not big to use. Convenient, so why is this?
Let's first understand the principle of the wireless wrist strap: the wireless wrist strap adopts the corona discharge effect and the principle of tip discharge. When the accumulated charge exceeds a certain value, it discharges into the space due to the potential difference, so as to achieve the purpose of eliminating static electricity. The characteristic is that it is convenient to use and does not need to be grounded.
For companies that control the HBM<100V workshop area in accordance with the requirements of S20.20, unlimited wristbands are not allowed. Because the high level of static electricity on the human body cannot be effectively released, the wireless wrist strap we wear may directly cause failure or damage to the static sensitive device when it comes into contact with it. Therefore, the wireless wrist strap cannot be used in the electronics manufacturing industry.
