因靜電會(huì)減少產(chǎn)品優(yōu)率,電磁干擾會(huì)中斷自動(dòng)設(shè)備運(yùn)行,靜電吸附會(huì)增加表面微粒收集的難度,因此對(duì)靜電的產(chǎn)生進(jìn)行控制也是必要的。因?yàn)殪o電電荷事實(shí)上會(huì)把污染物吸附在產(chǎn)品或工具表面,靜電吸附正變?yōu)闈崈羰矣^注的焦點(diǎn)。例如,將4英寸晶片充電至1KV時(shí),對(duì)直徑為1微米的微粒的吸附力將達(dá)到830000英磅/平方英寸。因此,與重力、空氣動(dòng)力和粘附力相比,帶電物體與微粒間的靜電吸附將更強(qiáng)。
Due to static electricity will reduce the product's excellent rate, the electromagnetic interference will interrupt automatic equipment operation, electrostatic adsorption will increase the difficulty of the surface particles collection, therefore the production of static electricity is necessary. Because of the fact that the electrostatic charge will be absorbed in the product or the surface of the tool, the electrostatic adsorption is becoming the focus of the clean room. For example, the 4 inch wafer charge to 1KV, the diameter of 1 micron particle adsorption capacity will reach 830000 pounds per square inch. Therefore, compared with the gravity, the air force and the adhesion force, the electrostatic adsorption between the charged object and the particle will be stronger.
在空氣凈化工程 http://www.jnjkjh.com/ 中的靜電危害主要表現(xiàn)在:
The main performance of electrostatic hazard in air purification project:
1.吸附灰塵。由于靜電吸附作用，潔凈室內(nèi)空氣微粒吸附在電子元器件表面和墻壁表面，影響產(chǎn)品質(zhì)量和潔凈度。靜電也成為潔凈室新的發(fā)塵源。
1 Adsorption of dust. Due to the electrostatic interaction, the clean indoor air particles adsorbed on the surface of the electronic components surface and wall, affecting product quality and cleanliness. Static electricity has become a new source of dust in the clean room.
2.誘發(fā)火災(zāi)與爆炸。電子工業(yè)潔凈室中會(huì)大量使用易燃易爆氣體、液體和有機(jī)溶劑，靜電會(huì)成為這些氣（液）體和溶劑的引火源，引起火災(zāi)或爆炸。
2 induced fire and explosion. Electronic industrial clean room will be a large number of the use of flammable and explosive gas, liquid and organic solvent, static electricity will become the gas (liquid) and solvent ignition source, causing a fire or explosion.
3.電暈放電，或火花放電，發(fā)出噪聲，干擾電子設(shè)備和電子元器件。
3 corona discharge, or spark discharge, the issue of noise, the interference of electronic equipment and electronic components.
4.產(chǎn)生靜電電場(chǎng)，使電子元器件短路、疲勞或破損。
4 to produce an electric field, so that the electronic components short circuit, fatigue or damage.
