For today's electronic products, we should cover all ESD substrates by designing a solid ESD structure in an integrated circuit, but in most cases, engineers default that the device is safe and compliant, and ESD protection is rarely considered. ESD (Electro-Static discharge) means \"electrostatic discharge\". ESD is a discipline formed since the middle of the 20th century to study the generation, harm and protection of static electricity. Therefore, it is customary to refer to the equipment used for electrostatic protection as ESD, and the Chinese name is electrostatic impedance device. The definition of electrostatic discharge or ESD is the transfer of electrostatic charges between objects or surfaces under different electrostatic potentials. Discharge will release ultra-high voltage in a short time, in the kilovolt (kV) range of 1 to 100 nanoseconds (ns).
Ion fans and ion nozzles can solve electrostatic hazards in the photoelectric industry, electronics industry, and semiconductor industry. Why do they use static electricity as a killer? Why do they regard electrostatic protection as a major project?
Static electricity is generated when two objects made of different electrically neutral materials touch and then separate.
1) Contact between objects A and B electrically neutral objects A and B (with equal amounts of positive and negative charges)
As we all know, ionization blowers can effectively remove static electricity. It has excellent antistatic properties to prevent static electricity pollution and damage.
According to different incentives, the electrostatic damage to semiconductor devices can be divided into three types: human body, machine equipment and semiconductor device. When static electricity comes into contact with the main body of the device wire, the device occurs due to discharge and charges
Many companies believe that as long as they purchase an ion fan, they can easily solve the problem of static electricity. However, they do not consider external reasons and may cause inefficiency of anti-static equipment. It may cause the problem of non-conformity of products.
Many companies regard the desktop ionization fan as normal fun. They will think that the product is not damaged and the appearance is not damaged, so it can be used for a long time. In fact, this is wrong.
