為什么工(gong)控主板(ban)的價格比(bi)商用(yong)主板(ban)高?相信很多(duo)用(yong)戶朋友都有(you)這個疑(yi)問，下面澤創偉業小(xiao)編就(jiu)來(lai)給大家分析下。
一、保護功能
商用主板沒有提供的任何的保護功能;
工控(kong)主板通過特殊(shu)設計(ji)，在遇到死機等異常(chang)情況，可以實現看門狗自動重(zhong)新啟動、防(fang)浪涌沖擊等功能，全力的(de)保證(zheng)系(xi)統在惡劣環(huan)境的(de)高(gao)穩定性(xing)的(de)要求。
二、工作溫度與散熱方式
商用主板基本(ben)只能在5℃~38℃之間的環境溫度中使用，對機(ji)構的散熱(re)要求低(di)，講究外觀夠炫夠酷。
工(gong)(gong)控(kong)主板(ban)可(ke)以在-20℃~60℃之間的(de)(de)環(huan)境(jing)中穩定、無(wu)故障的(de)(de)工(gong)(gong)作，甚(shen)至(zhi)某些工(gong)(gong)業主板(ban)采用特(te)殊(shu)的(de)(de)寬溫設計，溫度(du)范圍可(ke)達-20度(du)~70度(du)。這對機(ji)(ji)(ji)構(gou)的(de)(de)散(san)熱(re)方案(an)，散(san)熱(re)效(xiao)率都是(shi)一個嚴峻的(de)(de)考(kao)驗。在工(gong)(gong)控(kong)主板(ban)機(ji)(ji)(ji)構(gou)的(de)(de)散(san)熱(re)設計上，必須(xu)使用的(de)(de)特(te)殊(shu)散(san)熱(re)設計，甚(shen)至(zhi)還(huan)采用全鋁(lv)制的(de)(de)機(ji)(ji)(ji)構(gou)外(wai)殼，而且對CPU、南北橋和硬盤等發(fa)熱(re)大戶(hu)，進行特(te)殊(shu)處理，保證工(gong)(gong)控(kong)主板(ban)和整機(ji)(ji)(ji)的(de)(de)正常運(yun)行。
很多(duo)工控機(ji)由于(yu)在惡(e)劣的(de)(de)(de)(de)(de)應用(yong)(yong)(yong)環境下(例如潮濕(shi)、振動、多(duo)塵、輻射、高溫等(deng)等(deng)應用(yong)(yong)(yong)環境)使用(yong)(yong)(yong)，空氣中的(de)(de)(de)(de)(de)塵埃和鹽分，都會對主板(ban)(ban)(ban)造成腐蝕(shi)，影響主板(ban)(ban)(ban)的(de)(de)(de)(de)(de)正常(chang)使用(yong)(yong)(yong)，因此(ci)很多(duo)工控機(ji)有必要采(cai)用(yong)(yong)(yong)無風(feng)扇(shan)(shan)的(de)(de)(de)(de)(de)機(ji)箱結構，防止惡(e)劣環境對系統造成傷害。但(dan)是全(quan)密封無風(feng)扇(shan)(shan)的(de)(de)(de)(de)(de)結構，因為熱源的(de)(de)(de)(de)(de)互(hu)相干(gan)擾，對主板(ban)(ban)(ban)的(de)(de)(de)(de)(de)性能和穩(wen)定性的(de)(de)(de)(de)(de)要求(qiu)比較高，對機(ji)構的(de)(de)(de)(de)(de)散(san)(san)熱方(fang)式和散(san)(san)熱效(xiao)能的(de)(de)(de)(de)(de)要求(qiu)很高，務必要將(jiang)積熱有效(xiao)散(san)(san)發出去。
三、使用環境
工控主板常在惡劣環境下工作(壽命期內永久開機、氣候惡劣、潮濕、振動、多塵、輻射、高溫等等)，而這些環境下是商用主板無法勝任，當今商業主板大部分只能運行在安定的環境下(工作時間短、室內、常溫等等)。
四、主板元器件的用料與設計：
商(shang)用(yong)主板：
商(shang)用(yong)(yong)主(zhu)板由于其更新(xin)換(huan)代的(de)(de)速度比較(jiao)快，且對產(chan)品的(de)(de)穩定性(xing)及使用(yong)(yong)環境的(de)(de)要求比較(jiao)低(di)，故此追(zhui)求的(de)(de)是(shi)產(chan)品的(de)(de)時效(xiao)性(xing)，以及本(ben)身產(chan)品的(de)(de)市場定位(wei)，對元(yuan)器(qi)件選擇(ze)要求上一(yi)般(ban)只需滿足系(xi)統運行(xing)2到(dao)3年的(de)(de)使用(yong)(yong)壽命即可(3年之后(hou)大(da)部(bu)分已經更新(xin)換(huan)代了)，元(yuan)器(qi)件的(de)(de)用(yong)(yong)料上使用(yong)(yong)普通級別的(de)(de)就可以了。例如電容(rong)，商(shang)用(yong)(yong)主(zhu)板都是(shi)大(da)量使用(yong)(yong)普通的(de)(de)電解電容(rong)，一(yi)是(shi)出(chu)于商(shang)用(yong)(yong)市場產(chan)品的(de)(de)使用(yong)(yong)考(kao)慮，二是(shi)為降低(di)主(zhu)板的(de)(de)成本(ben)考(kao)慮。
工(gong)控主板：
1)工控主板的元器件
工控主板選(xuan)料會選(xuan)用(yong)經(jing)過長(chang)時間，高(gao)要(yao)(yao)求(qiu)驗證元(yuan)器(qi)(qi)件(jian)，用(yong)以保證產(chan)品在惡劣條件(jian)下(xia)高(gao)可(ke)靠(kao)性要(yao)(yao)求(qiu)。例如(ru)(ru)工控主板的(de)元(yuan)器(qi)(qi)件(jian)需(xu)要(yao)(yao)適(shi)應(ying)寬溫(wen)環境(jing)(-20℃~60℃)，如(ru)(ru)固態電容(rong)器(qi)(qi)，保證在惡劣環境(jing)下(xia)(壽命期內(nei)永(yong)久開(kai)機(ji)、氣候惡劣、潮濕、振動、多塵(chen)、輻(fu)射、高(gao)溫(wen)等(deng)(deng)等(deng)(deng))正常工作;主板元(yuan)器(qi)(qi)件(jian)需(xu)要(yao)(yao)耐高(gao)溫(wen)、抗(kang)潮濕等(deng)(deng)等(deng)(deng)。
2)工控主板的電容
工(gong)控(kong)主(zhu)(zhu)板(ban)采(cai)用(yong)(yong)(yong)的(de)(de)(de)(de)是高(gao)(gao)(gao)質量(liang)的(de)(de)(de)(de)貼片式(shi)的(de)(de)(de)(de)固(gu)(gu)態電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)、鉭(tan)(tan)、陶(tao)瓷(ci)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)，即使(shi)使(shi)用(yong)(yong)(yong)的(de)(de)(de)(de)電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)，對其品質、性能及(ji)(ji)(ji)壽命要(yao)(yao)求也(ye)遠高(gao)(gao)(gao)于(yu)商用(yong)(yong)(yong)產(chan)品，現在的(de)(de)(de)(de)工(gong)控(kong)主(zhu)(zhu)板(ban)都(dou)基本上采(cai)用(yong)(yong)(yong)固(gu)(gu)態電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)，特別中(zhong)高(gao)(gao)(gao)端的(de)(de)(de)(de)工(gong)控(kong)主(zhu)(zhu)板(ban)。商用(yong)(yong)(yong)主(zhu)(zhu)板(ban)基本都(dou)是大(da)量(liang)采(cai)用(yong)(yong)(yong)針(zhen)腳(jiao)式(shi)的(de)(de)(de)(de)大(da)電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)，因(yin)為大(da)電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)成本低、容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)值大(da)一個(ge)可以頂多個(ge)貼片或坦電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)。從性質來說，電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)穩(wen)定性不及(ji)(ji)(ji)鉭(tan)(tan)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)、陶(tao)瓷(ci)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)高(gao)(gao)(gao)，壽命不及(ji)(ji)(ji)它們長，耐(nai)高(gao)(gao)(gao)溫程度不及(ji)(ji)(ji)它們好。貼片式(shi)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)比針(zhen)腳(jiao)式(shi)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)更加穩(wen)定。從價格上，鉭(tan)(tan)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)比普通的(de)(de)(de)(de)電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)要(yao)(yao)貴(gui)，且由于(yu)鉭(tan)(tan)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)量(liang)較(jiao)小(xiao)，使(shi)用(yong)(yong)(yong)在主(zhu)(zhu)板(ban)上時(shi)，需要(yao)(yao)使(shi)用(yong)(yong)(yong)更多數量(liang)的(de)(de)(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)，單單鉭(tan)(tan)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)成本就是電(dian)(dian)解(jie)(jie)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)幾十(shi)倍，這(zhe)也(ye)是導(dao)致工(gong)控(kong)主(zhu)(zhu)板(ban)比商用(yong)(yong)(yong)主(zhu)(zhu)板(ban)成本價格高(gao)(gao)(gao)的(de)(de)(de)(de)原因(yin)之一。隨(sui)著(zhu)國產(chan)固(gu)(gu)態電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器廠家越來越多，固(gu)(gu)態電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器的(de)(de)(de)(de)價格的(de)(de)(de)(de)下(xia)降，現在的(de)(de)(de)(de)高(gao)(gao)(gao)檔次的(de)(de)(de)(de)商用(yong)(yong)(yong)主(zhu)(zhu)板(ban)都(dou)在使(shi)用(yong)(yong)(yong)固(gu)(gu)態電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)(rong)器。
3)工控主板的PCB
商用主(zhu)(zhu)板(ban)(ban)采(cai)用的是(shi)4層(ceng)PCB設計，一般的PCB線(xian)路板(ban)(ban)分有四層(ceng)，最上(shang)和最下(xia)的兩(liang)(liang)層(ceng)是(shi)信號(hao)層(ceng)，中(zhong)間兩(liang)(liang)層(ceng)是(shi)接地層(ceng)和電(dian)源(yuan)層(ceng)，將接地和電(dian)源(yuan)層(ceng)放在(zai)中(zhong)間。工業主(zhu)(zhu)板(ban)(ban)采(cai)用的是(shi)6層(ceng)以上(shang)PCB線(xian)路板(ban)(ban)設計，其設計是(shi)為了加強主(zhu)(zhu)板(ban)(ban)的抗(kang)電(dian)磁干擾、電(dian)磁兼容(rong)能(neng)力，增強主(zhu)(zhu)板(ban)(ban)的穩定性(xing)等等。
4)工(gong)控主板的(de)壽(shou)命
與商用(yong)主(zhu)板(ban)2到3年(nian)(nian)使用(yong)壽(shou)命(ming)不(bu)同，大多數的工(gong)控(kong)主(zhu)板(ban)壽(shou)命(ming)要求在3年(nian)(nian)以(yi)上(shang)，部分高(gao)品質的工(gong)控(kong)主(zhu)板(ban)，使用(yong)壽(shou)命(ming)甚至(zhi)達到5—7年(nian)(nian)。
一、保護功能
商用主板沒有提供的任何的保護功能;

二、工作溫度與散熱方式
商用主板基本(ben)只能在5℃~38℃之間的環境溫度中使用，對機(ji)構的散熱(re)要求低(di)，講究外觀夠炫夠酷。
工(gong)(gong)控(kong)主板(ban)可(ke)以在-20℃~60℃之間的(de)(de)環(huan)境(jing)中穩定、無(wu)故障的(de)(de)工(gong)(gong)作，甚(shen)至(zhi)某些工(gong)(gong)業主板(ban)采用特(te)殊(shu)的(de)(de)寬溫設計，溫度(du)范圍可(ke)達-20度(du)~70度(du)。這對機(ji)(ji)(ji)構(gou)的(de)(de)散(san)熱(re)方案(an)，散(san)熱(re)效(xiao)率都是(shi)一個嚴峻的(de)(de)考(kao)驗。在工(gong)(gong)控(kong)主板(ban)機(ji)(ji)(ji)構(gou)的(de)(de)散(san)熱(re)設計上，必須(xu)使用的(de)(de)特(te)殊(shu)散(san)熱(re)設計，甚(shen)至(zhi)還(huan)采用全鋁(lv)制的(de)(de)機(ji)(ji)(ji)構(gou)外(wai)殼，而且對CPU、南北橋和硬盤等發(fa)熱(re)大戶(hu)，進行特(te)殊(shu)處理，保證工(gong)(gong)控(kong)主板(ban)和整機(ji)(ji)(ji)的(de)(de)正常運(yun)行。
很多(duo)工控機(ji)由于(yu)在惡(e)劣的(de)(de)(de)(de)(de)應用(yong)(yong)(yong)環境下(例如潮濕(shi)、振動、多(duo)塵、輻射、高溫等(deng)等(deng)應用(yong)(yong)(yong)環境)使用(yong)(yong)(yong)，空氣中的(de)(de)(de)(de)(de)塵埃和鹽分，都會對主板(ban)(ban)(ban)造成腐蝕(shi)，影響主板(ban)(ban)(ban)的(de)(de)(de)(de)(de)正常(chang)使用(yong)(yong)(yong)，因此(ci)很多(duo)工控機(ji)有必要采(cai)用(yong)(yong)(yong)無風(feng)扇(shan)(shan)的(de)(de)(de)(de)(de)機(ji)箱結構，防止惡(e)劣環境對系統造成傷害。但(dan)是全(quan)密封無風(feng)扇(shan)(shan)的(de)(de)(de)(de)(de)結構，因為熱源的(de)(de)(de)(de)(de)互(hu)相干(gan)擾，對主板(ban)(ban)(ban)的(de)(de)(de)(de)(de)性能和穩(wen)定性的(de)(de)(de)(de)(de)要求(qiu)比較高，對機(ji)構的(de)(de)(de)(de)(de)散(san)(san)熱方(fang)式和散(san)(san)熱效(xiao)能的(de)(de)(de)(de)(de)要求(qiu)很高，務必要將(jiang)積熱有效(xiao)散(san)(san)發出去。

四、主板元器件的用料與設計：
商(shang)用(yong)主板：
商(shang)用(yong)(yong)主(zhu)板由于其更新(xin)換(huan)代的(de)(de)速度比較(jiao)快，且對產(chan)品的(de)(de)穩定性(xing)及使用(yong)(yong)環境的(de)(de)要求比較(jiao)低(di)，故此追(zhui)求的(de)(de)是(shi)產(chan)品的(de)(de)時效(xiao)性(xing)，以及本(ben)身產(chan)品的(de)(de)市場定位(wei)，對元(yuan)器(qi)件選擇(ze)要求上一(yi)般(ban)只需滿足系(xi)統運行(xing)2到(dao)3年的(de)(de)使用(yong)(yong)壽命即可(3年之后(hou)大(da)部(bu)分已經更新(xin)換(huan)代了)，元(yuan)器(qi)件的(de)(de)用(yong)(yong)料上使用(yong)(yong)普通級別的(de)(de)就可以了。例如電容(rong)，商(shang)用(yong)(yong)主(zhu)板都是(shi)大(da)量使用(yong)(yong)普通的(de)(de)電解電容(rong)，一(yi)是(shi)出(chu)于商(shang)用(yong)(yong)市場產(chan)品的(de)(de)使用(yong)(yong)考(kao)慮，二是(shi)為降低(di)主(zhu)板的(de)(de)成本(ben)考(kao)慮。
