There are many anti-static supplies, such as:
Anti-static clothes, shoes, hats, gloves, cuffs.
Anti-static plastic box, hollow plate box, knife card, chair.
Anti-static table mat, wrist strap, foot bowl belt, tweezers.
Anti-static component box, PCB turnover box, turnover car.
Anti-static trolley, shelves, workstations, floor wax.
Anti-static shielding bags, mesh bags, moisture-proof bags.
Static electricity (static electricity), is a charge at rest. When the charge is gathered on an object or the surface of the formation of static electricity, and the charge is divided into positive charge and negative charge two kinds, that is to say, the phenomenon of static electricity is also divided into two kinds that is, positive static electricity and negative static electricity.
When the positive charge gathered in an object on the formation of a positive electrostatic, when the negative charge gathered in an object on the formation of a negative electrostatic, but whether positive or negative electrostatic, when the electrostatic object in contact with the zero-potential object (grounded object) or with its potential difference between the object will occur when the charge is transferred, that is, we see the daily phenomenon of spark discharge.
People often encounter this phenomenon in their daily lives: when they undress at night and go to bed, they often hear crackling sounds in the dark, accompanied by blue light, when they meet and shake hands, their fingers just touch each other, and they will suddenly feel a pinprick of pain in their fingertips, which makes them startled; in the morning, when they comb their hair, their hair is often "floating" up, and the more they do it, the more messy it gets. The more you do it, the more messy it gets.
Harms caused by electrostatic attraction (ESA):
(1) Electronics industry: adsorption of dust, resulting in integrated circuits and semiconductor components of pollution, greatly reducing the yield.
(2) Film and plastic industry: make film or film winding is not aligned; film, CD plastic disk stained with dust, affecting the quality.
(3) paper printing industry: paper winding is not aligned, overprinting is not allowed, the absorption of dirt is serious, and even paper adhesion, affecting production.
(4) textile industry: cause root silk fluttering, tangled flowers broken head, yarn tangled and other hazards.
The hazards of static electricity are **** witnessed, and now more and more manufacturers have begun to implement various degrees of anti-static measures and projects.
However, it is important to recognize that the perfect and effective anti-static project in accordance with the actual situation of different enterprises and different operating objects, the development of appropriate countermeasures. Anti-static measures should be systematic and comprehensive, otherwise, it may be twice the effort, and even cause destructive counterproductive.
