防(fang)靜電(dian)(dian)(dian)地(di)(di)板又叫做耗散靜電(dian)(dian)(dian)地(di)(di)板，是一(yi)種(zhong)地(di)(di)板，當(dang)它(ta)接地(di)(di)或(huo)連(lian)接到(dao)任何較低電(dian)(dian)(dian)位點時(shi)，使(shi)(shi)電(dian)(dian)(dian)荷(he)能(neng)夠(gou)耗散，以(yi)電(dian)(dian)(dian)阻(zu)在10的(de)5次方(fang)到(dao)10的(de)9次方(fang)歐姆(mu)之間(jian)為特征。《GB50174-2008電(dian)(dian)(dian)子信息系統機(ji)(ji)房設計規范》第20頁8.3.1節(jie)規定(ding)：防(fang)靜電(dian)(dian)(dian)地(di)(di)板或(huo)地(di)(di)面的(de)表面電(dian)(dian)(dian)阻(zu)或(huo)體積電(dian)(dian)(dian)阻(zu)應(ying)為2.5×104～1.0×109Ω。計算機(ji)(ji)房的(de)防(fang)靜電(dian)(dian)(dian)技術，是屬于機(ji)(ji)房安全(quan)與(yu)防(fang)護范疇的(de)一(yi)部(bu)分。靜電(dian)(dian)(dian)引起(qi)的(de)問題不僅(jin)硬(ying)件(jian)人(ren)員很難查出，有時(shi)還會使(shi)(shi)軟件(jian)人(ren)員誤(wu)認為是軟件(jian)故障，從而造成工作混亂。此外，靜電(dian)(dian)(dian)通過人(ren)體對(dui)計算機(ji)(ji)或(huo)其他(ta)設備放電(dian)(dian)(dian)時(shi)（即所謂的(de)打火）當(dang)能(neng)量(liang)達到(dao)固定(ding)值，也會給人(ren)以(yi)觸(chu)電(dian)(dian)(dian)的(de)感(gan)覺（例(li)如(ru)有時(shi)觸(chu)摸電(dian)(dian)(dian)腦(nao)顯(xian)示器或(huo)機(ji)(ji)箱時(shi)）
注意：防(fang)靜電地(di)板鋪設后，需要(yao)(yao)要(yao)(yao)進行防(fang)靜電接(jie)地(di)處(chu)理(li)并(bing)接(jie)保護(hu)電阻盒，不(bu)然(ran)起不(bu)到防(fang)靜電作用(yong)。
