Anti-static protection
In the electronic production environment including LCD photoelectric manufacturing, the discharge time is mostly microseconds or nanoseconds, but the peak energy of instantaneous discharge can reach hundreds of watts or more, and the peak current can reach several to ten amperes. The process is sufficient to form The damage of microelectronic devices (components); another thing that cannot be ignored is that electrostatic adsorption of dust has an increasing impact on the production of the microelectronics industry.
In fact, in the environment we live in, it is also ubiquitous, and not all companies that are still relying on high energy consumption and high pollution to maintain, just say that the space we are in now is also full of a large number of fine dust particles. If it’s rated by level, it’s at least one hundred thousand. We breathe them all the time. But fortunately, our human body has a strong filter (respiratory system) and ** system, which is generally good for health. For people, it is a balance of the physiological system, which is not a major problem.
However, in the microelectronics or optoelectronics industry, this matter is much more demanding, and a good air cleaning system must be established. The system purification level can be 10,000, 1,000, 100, or even 10. Low, the higher the actual cleanliness, as shown in the table (purification level standards of various industries)
In terms of dust control, what we can achieve is nothing more than two ways of thinking.
A. Efforts to improve the cleanliness of your production environment, such as doing purification projects or improving the level of purification projects and using purification tools, gloves, cotton swabs, hoods, masks, etc.;
B. No one can clean the space, that is, we must try to prevent the fine dust particles staying in the space from being adsorbed on our products, because its adsorption has a lot to do with static electricity. It is necessary to remove the static electricity first. Elimination, so that static electricity can reduce or not adsorb the fine dust. Therefore, we can use static eliminator and sticky roller to improve the cleanliness of the surface of the object.
Is there a device that can remove static electricity and stick to dust? The answer is: yes. If combined, it is the electrostatic precipitator (automatic electrostatic precipitator roller machine). In the optoelectronic industry, many optical molds are flat, not uneven, so its use is becoming more and more widespread. Its main principle is:
The cleaning principle of the electrostatic dust removal machine is to use a high-efficiency static elimination system to remove materials with static dust, and then pass the dust removal roller** to the surface of the material. The dust will immediately transfer to the upper dust collection roller, and the dust on the dust collection roller will be determined. Time is with cleaning liquid or dust removal tape**; after the material is cleaned by the dust removal roller, the static electricity is eliminated by a static eliminator, so that the cleaning operation is completed. The pictures (illustrations) are as follows:

In short, to solve these static electricity problems in the production process of optoelectronics and other electronics, we must first understand its harmful mechanism, and then the harmful way of static electricity. After we solve the static electricity problem, we can protect it as much as possible and improve it. The yield rate of our products, save product costs, and improve production efficiency.
