That is because the machine or the workshop that produces the wafers is equipped with an FFU high-efficiency filter. When the airflow rubs against the product, it generates static electricity. When the static electricity accumulates to a certain amount, it will absorb dust. Therefore, we recommend installing a static eliminator without a gas source at the lower end of the high efficiency filter to ensure the dynamic balance of the entire workshop.
When the surface of the object is positively charged, the negative ions emitted by the static eliminator will neutralize it. When the surface of the object is negatively charged, the positive ions emitted by the static eliminator will neutralize it.
Speaking of this, customers often have some doubts. For example, when the static electricity on the product is eliminated by the static eliminator, the static eliminator is still emitting positive and negative ions. Will it recharge the static electricity on my product? the answer is negative. A static eliminator is a process of reducing the static electricity on the surface of an object. When there is no static electricity on the surface of the object, a part of the positive and negative ions emitted by the static eliminator will neutralize itself, and a part of it will attract the opposite ions in other places.
