一、覆銅板是什么

覆(fu)銅(tong)板是將電(dian)子(zi)玻纖布或其它增強材料(liao)浸以樹脂(zhi)，一面或雙面覆(fu)以銅(tong)箔并經熱壓而制(zhi)(zhi)成(cheng)的(de)一種板狀材料(liao)，被(bei)稱(cheng)為(wei)覆(fu)銅(tong)箔層壓板（Copper Clad Laminate，CCL），簡稱(cheng)為(wei)覆(fu)銅(tong)板。各種不(bu)同(tong)(tong)形(xing)式(shi)、不(bu)同(tong)(tong)功能的(de)印制(zhi)(zhi)電(dian)路(lu)(lu)板，都是在覆(fu)銅(tong)板上有選擇地進(jin)行(xing)加工(gong)(gong)、蝕(shi)刻、鉆孔及鍍銅(tong)等工(gong)(gong)序，制(zhi)(zhi)成(cheng)不(bu)同(tong)(tong)的(de)印制(zhi)(zhi)電(dian)路(lu)(lu)。

覆(fu)銅(tong)(tong)板(ban)(ban)作為印制(zhi)(zhi)(zhi)(zhi)電路(lu)(lu)(lu)板(ban)(ban)制(zhi)(zhi)(zhi)(zhi)造中的(de)(de)(de)基板(ban)(ban)材料，對印制(zhi)(zhi)(zhi)(zhi)電路(lu)(lu)(lu)板(ban)(ban)主要起(qi)互連導通(tong)、絕緣(yuan)和(he)支撐的(de)(de)(de)作用，對電路(lu)(lu)(lu)中信號的(de)(de)(de)傳(chuan)輸(shu)速度、能(neng)量(liang)損失和(he)特性(xing)(xing)(xing)(xing)阻抗等(deng)有(you)很(hen)大(da)(da)的(de)(de)(de)影(ying)響，因(yin)此，印制(zhi)(zhi)(zhi)(zhi)電路(lu)(lu)(lu)板(ban)(ban)的(de)(de)(de)性(xing)(xing)(xing)(xing)能(neng)、品質、制(zhi)(zhi)(zhi)(zhi)造中的(de)(de)(de)加工性(xing)(xing)(xing)(xing)、制(zhi)(zhi)(zhi)(zhi)造水平、制(zhi)(zhi)(zhi)(zhi)造成本(ben)以及(ji)長期(qi)的(de)(de)(de)可靠性(xing)(xing)(xing)(xing)及(ji)穩定性(xing)(xing)(xing)(xing)在很(hen)大(da)(da)程度上取決于(yu)覆(fu)銅(tong)(tong)板(ban)(ban)。

二、覆銅板和pcb板的區別

PCB也(ye)就是印制電(dian)(dian)路(lu)板(ban)(ban)，別(bie)稱印刷線(xian)路(lu)板(ban)(ban)，PCB是電(dian)(dian)子(zi)(zi)(zi)元(yuan)器(qi)(qi)(qi)件(jian)的支撐(cheng)體，同時PCB也(ye)是電(dian)(dian)子(zi)(zi)(zi)元(yuan)器(qi)(qi)(qi)件(jian)電(dian)(dian)氣(qi)連接的載體。PCB能夠提供各元(yuan)器(qi)(qi)(qi)件(jian)固定裝配械支撐(cheng)，實現電(dian)(dian)子(zi)(zi)(zi)元(yuan)器(qi)(qi)(qi)件(jian)之間的布線(xian)、電(dian)(dian)氣(qi)連接和電(dian)(dian)絕緣。

覆(fu)(fu)銅(tong)板全(quan)名覆(fu)(fu)銅(tong)箔層壓板，簡稱(cheng)為(wei)CCL。覆(fu)(fu)銅(tong)板是(shi)在印制電路板制造中的(de)(de)基板材(cai)料，PCB的(de)(de)各項(xiang)性能在很(hen)大程度上(shang)取(qu)決于(yu)覆(fu)(fu)銅(tong)板。

PCB并不是覆銅板。品牌覆銅板是(shi)在膠質板(ban)(ban)的(de)一(yi)面或者雙面覆(fu)(fu)有銅箔(bo)的(de)板(ban)(ban)材，覆(fu)(fu)銅板(ban)(ban)是(shi)制作單面或者雙面PCB的(de)材料。PCB是(shi)將電路的(de)布局布線圖(tu)印制在覆(fu)(fu)銅板(ban)(ban)上，然后經過各種工藝后的(de)電路板(ban)(ban)。

值得一提的是，PCB除了單(dan)面(mian)和雙面(mian)之外(wai)，還(huan)有4層(ceng)、6層(ceng)、8層(ceng)、10層(ceng)的。
