During the processing and production of LED lamp beads, certain anti-static measures should be taken, such as grounding the workbench, wearing anti-static clothing, anti-static rings, and anti-static gloves for workers. If conditions permit, anti-static ion fans can be installed, while ensuring that the humidity in the workshop is around 65% to avoid static electricity caused by excessively dry air, especially green LED lamp beads are relatively more susceptible to static damage. In addition, the anti-static ability of LEDs of different quality grades also varies, and LED beads of higher quality grades have stronger anti-static ability. There may be many friends who are not very familiar with static electricity. Here, I will introduce the knowledge of static electricity in more detail: the essence of static electricity is the existence of residual charges. Charge is all physical quantities related to the essence of electrostatic phenomena, also known as ESD in English.
Potential, electric field, current, and other related quantities are physical quantities generated by the presence or movement of charges. Many electrostatic problems are caused by people's lack of ESD awareness, and even now many people suspect that ESD can cause damage to electronic products. This is because most ESD damage occurs below the human perception, as the perceived voltage of electrostatic discharge by the human body is about 3KV, and many electronic components can be damaged at hundreds or even tens of volts. Usually, there is no clear boundary after electronic components are damaged by ESD. After installing the components on a PCB, testing can result in many problems, and analysis is also quite difficult. Especially for potential damage, it is difficult to measure significant changes in performance even with precision instruments, so many electronic engineers and designers suspect ESD. In recent years, experiments have confirmed that the reliability of electronic products significantly decreases after a certain period of time due to this potential damage.
