工(gong)(gong)(gong)控(kong)主(zhu)板(ban)(ban)(ban)是(shi)區別于普通(tong)電腦(nao)(nao)的主(zhu)板(ban)(ban)(ban)，是(shi)工(gong)(gong)(gong)控(kong)電腦(nao)(nao)的組成部分。由于工(gong)(gong)(gong)業(ye)生(sheng)產環(huan)境(jing)惡(e)劣，通(tong)常要(yao)求(qiu)在(zai)不同的溫度(du)下進行(xing)，工(gong)(gong)(gong)作(zuo)(zuo)溫度(du)范(fan)圍可(ke)達-20度(du)~70度(du)，而且工(gong)(gong)(gong)作(zuo)(zuo)濕度(du)的范(fan)圍也有(you)要(yao)求(qiu)，達到了(le)(le)非凝(ning)露0~95%，同時(shi)還可(ke)能(neng)在(zai)粉塵較多，有(you)電磁干擾和輻射(she)的環(huan)境(jing)長時(shi)間工(gong)(gong)(gong)作(zuo)(zuo)。在(zai)這些(xie)環(huan)境(jing)下，普通(tong)的電腦(nao)(nao)主(zhu)板(ban)(ban)(ban)并不適合，因而研(yan)發出了(le)(le)一種能(neng)夠適應(ying)惡(e)劣生(sheng)產環(huan)境(jing)的工(gong)(gong)(gong)控(kong)主(zhu)板(ban)(ban)(ban)，工(gong)(gong)(gong)控(kong)主(zhu)板(ban)(ban)(ban)的要(yao)求(qiu)是(shi)工(gong)(gong)(gong)作(zuo)(zuo)時(shi)間達到了(le)(le)使(shi)用壽命之長，簡直是(shi)工(gong)(gong)(gong)業(ye)生(sheng)產控(kong)制(zhi)行(xing)業(ye)的福音。

　　工控主板可以在-20℃~60℃之間的環境中穩定、無故障的工作，甚至某些工業主板采用特殊的寬溫設計，溫度范圍可達-20度~70度。這對機構的散熱方案，散熱效率都是一個嚴峻的考驗。在工控主板機構的散熱設計上，必須使用的特殊散熱設計，甚至還采用全鋁制的機構外殼，而且對CPU、南北橋和硬盤等發熱大戶，進行特殊處理，保證工控主板和整機的正常運行。

　　工控主板的強大(da)性能(neng)使得工控主板應用(yong)于各(ge)行各(ge)業，主要(yao)有軍事生產工業，政府(fu)機構，電力(li)生產，車載設備，專(zhuan)業設備控制，導航和銀行。
