什么是静电？

静(jing)(jing)(jing)电(dian)(dian)(dian)可以理(li)解为(wei)是(shi)(shi)相对静(jing)(jing)(jing)止不(bu)动的电(dian)(dian)(dian)荷，是(shi)(shi)宏(hong)观上可转(zhuan)移(yi)停留在某一(yi)处的电(dian)(dian)(dian)。静(jing)(jing)(jing)电(dian)(dian)(dian)放电(dian)(dian)(dian)是(shi)(shi)指静(jing)(jing)(jing)电(dian)(dian)(dian)由于电(dian)(dian)(dian)位不(bu)同(tong)，因(yin)接触、感应引起的静(jing)(jing)(jing)电(dian)(dian)(dian)转(zhuan)移(yi)过程。静(jing)(jing)(jing)电(dian)(dian)(dian)的产生(sheng)是(shi)(shi)因(yin)为(wei)两个不(bu)同(tong)材质的物体接触后再分离，一(yi)个物体会产生(sheng)带正电(dian)(dian)(dian)荷的静(jing)(jing)(jing)电(dian)(dian)(dian)，另一(yi)个会产生(sheng)带负电(dian)(dian)(dian)荷的静(jing)(jing)(jing)电(dian)(dian)(dian)。

什么是静电敏感度？

静(jing)电(dian)敏感度是指每种电(dian)子元(yuan)器件对(dui)静(jing)电(dian)破坏承受的能力。

静电对PCBA板、电子器件(jian)危害有哪些？

静(jing)电(dian)(dian)会对(dui)PCBA和(he)电(dian)(dian)子元(yuan)器件(jian)板(ban)造(zao)(zao)(zao)成(cheng)(cheng)损伤，即因静(jing)电(dian)(dian)放电(dian)(dian)造(zao)(zao)(zao)成(cheng)(cheng)的电(dian)(dian)子元(yuan)器件(jian)、PCBA板(ban)性能减弱、功能失(shi)效(xiao)（完(wan)全失(shi)效(xiao)、间歇性功能失(shi)效(xiao)造(zao)(zao)(zao)成(cheng)(cheng)的性能不(bu)稳定）。电(dian)(dian)子元(yuan)器件(jian)制造(zao)(zao)(zao)（含传送、运输过程）、印刷电(dian)(dian)路板(ban)、设备制造(zao)(zao)(zao)、设备使用都会受(shou)到(dao)静(jing)电(dian)(dian)的影响。

SMT行业静电(dian)防护原则(ze)有哪些？

①、在静电(dian)(dian)安(an)(an)全区安(an)(an)装(zhuang)、使(shi)用电(dian)(dian)子元器件；

②、用静电屏蔽容器运送、存储电(dian)(dian)子元(yuan)器件或电(dian)(dian)路板；

③、定期检测静电防护系统(tong)是否正常；

④、时刻牢记静电防(fang)护；

防静电着装

SMT生产企业(ye)对静电防护方(fang)法有哪些？

⑴、静电(dian)敏感(gan)度高的电(dian)子元(yuan)器件、电(dian)路板，不和塑胶制品(pin)、工具（含电(dian)脑(nao)及终端机）设备放一(yi)起。

⑵、所有工具、设备连接上地线(xian)。

⑶、使用静电防护桌(zhuo)垫；

⑷、遵从(cong)电气安全(quan)规定、静电防护规定；

⑸、穿戴静电防(fang)护(hu)手(shou)环及衣帽(mao)鞋(xie)；

⑹、及(ji)时(shi)发现静电破坏隐患(huan)。

对于SMT生(sheng)产(chan)线来说，静(jing)电(dian)可是“大(da)敌(di)”，因此做好静(jing)电(dian)防护(hu)非常有必要(yao)。随着(zhe)SMT生(sheng)产(chan)企(qi)业的智能(neng)化、自(zi)动化程度越来越高，生(sheng)产(chan)和存储(chu)环境环节的制度严格执行，企(qi)业已经能(neng)很好的应对静(jing)电(dian)带来的危害了。
