Ion fan and ion nozzle can solve the electrostatic hazards in the optoelectronics industry, electronics industry and semiconductor industry. Why do they take static as killers ? Why do they regard electrostatic protection as a major project?
In the semiconductor device production plant, due to the adsorption of dust on the chip, the yield of VLSI will be greatly reduced. Workers in production workshops wear clean work clothes. If the human body is electrostatically charged, dust and dirt are easily adsorbed. If these dust and dirt are brought to the operation site, the quality of the product will be affected, the performance of the product will deteriorate, and the yield will be greatly reduced. . If the radius of the adsorbed dust particles is larger than the line width, the thickness of the film is lower, and the product is most likely to be scrapped.
Although the electrostatic effect is the earliest experimental evidence of electricity, but in modern industrial processes, static electricity is still considered "unknown." The general industry of electrostatic hazards control technology can be described as very strange, often caused many misunders.
As long as there is static in the environment, it can cause harm to the product or even people. Often, one of two types of air ionization is used to dissipate electrostatic charges - alpha or corona. Corona has become the standard for many years and is familiar to most organizations.
What is the life expectancy of a static control device? A static control device will work for millions of cycles if the charged paper does not touch the fibers. Electro Static Technology recommends a distance of 2mm to 7mm between the fiber tips and the charged paper.
According to medical experts, the human body static electricity will bring a certain degree of harm. The static electricity generated by human disturbance can change the normal surface potential difference of the human body, the effect of cardiac electrophysiology on the normal process of ECG and does not interfere with normal conduction.
Static is generated when two objects made of different electrically neutral materials contact and then separate. 1) Contact between objects A and B Electrically neutral objects A and B (with equal quantities of positive and negative charges)
