銅排應用

銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)主要是(shi)用(yong)(yong)(yong)在一(yi)次線(xian)(xian)路上(shang)（大(da)電(dian)(dian)(dian)流(liu)的(de)(de)相(xiang)線(xian)(xian)、零線(xian)(xian)、地線(xian)(xian)都(dou)會(hui)用(yong)(yong)(yong)到銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)），在電(dian)(dian)(dian)柜(ju)上(shang)較大(da)電(dian)(dian)(dian)流(liu)的(de)(de)一(yi)次元器(qi)件的(de)(de)連(lian)接都(dou)是(shi)用(yong)(yong)(yong)銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)，比如一(yi)排(pai)(pai)(pai)電(dian)(dian)(dian)柜(ju)在柜(ju)與柜(ju)之間連(lian)接的(de)(de)是(shi)主母排(pai)(pai)(pai)，主母排(pai)(pai)(pai)分到每(mei)面電(dian)(dian)(dian)柜(ju)的(de)(de)開關電(dian)(dian)(dian)氣（隔離開關、斷(duan)路器(qi)等）上(shang)的(de)(de)是(shi)分支母排(pai)(pai)(pai)。銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)有(you)鍍(du)錫的(de)(de)也(ye)有(you)裸銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)，在電(dian)(dian)(dian)柜(ju)中銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)連(lian)接處一(yi)般都(dou)要做(zuo)鍍(du)錫處理和壓花(hua)處理或(huo)者加導電(dian)(dian)(dian)膏。空余處就有(you)加熱縮套(tao)管防護，也(ye)有(you)些是(shi)用(yong)(yong)(yong)絕緣油漆(qi)的(de)(de)。 用(yong)(yong)(yong)銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)主要考慮的(de)(de)是(shi)載(zai)流(liu)量，根據(ju)電(dian)(dian)(dian)流(liu)大(da)小選用(yong)(yong)(yong)適合的(de)(de)銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)，連(lian)接處的(de)(de)螺絲一(yi)定要上(shang)緊，否則電(dian)(dian)(dian)流(liu)大(da)時會(hui)出(chu)現燒熔(rong)銅(tong)(tong)(tong)(tong)排(pai)(pai)(pai)的(de)(de)可能(neng)。

鋰離子蓄電池(chi)要(yao)銅箔 copper foil for lithium ion battery

  應用(yong)于鋰(li)(li)離子蓄電池的(de)(de)負(fu)(fu)(fu)極(ji)集流(liu)體的(de)(de)制造的(de)(de)銅箔(bo)。這種(zhong)銅箔(bo)在(zai)(zai)鋰(li)(li)電池內即充當負(fu)(fu)(fu)極(ji)材料(liao)的(de)(de)載體，又作為負(fu)(fu)(fu)極(ji)電子收集與傳(chuan)輸體。所用(yong)的(de)(de)銅箔(bo)必(bi)須有良好的(de)(de)導(dao)電性(xing)(xing)。它應保證與活性(xing)(xing)物質具有良好的(de)(de)接(jie)觸性(xing)(xing)，能夠均勻的(de)(de)涂敷在(zai)(zai)負(fu)(fu)(fu)極(ji)材料(liao)上不(bu)脫落。它應與活性(xing)(xing)具有良好的(de)(de)接(jie)觸性(xing)(xing)，常州正極(ji)材料(liao)，良好的(de)(de)耐蝕性(xing)(xing)，表(biao)面光滑(hua)、厚度均勻性(xing)(xing)。

電解銅箔(bo)與壓(ya)延(yan)銅箔(bo)的(de)異同(tong)點！

壓延銅箔(bo)和電解銅箔(bo)厚度(du)的(de)控(kong)制(zhi)：通常廠里對銅箔(bo)的(de)厚度(du)有很(hen)嚴(yan)格的(de)要求，一般在0.3mil和3mil之間，正極(ji)材料(liao)廠家，有的(de)銅箔(bo)厚度(du)測試儀檢驗(yan)其品質。控(kong)制(zhi)銅箔(bo)的(de)薄(bo)度(du)主要是基于兩個理(li)由：  

1、均勻的(de)銅箔可以有(you)非常均勻的(de)電(dian)阻(zu)溫(wen)度系數(shu)(shu)，介電(dian)常數(shu)(shu)低(di)，這樣能讓信號傳輸損失更(geng)小(xiao)，這和電(dian)容(rong)要(yao)求(qiu)不同，電(dian)容(rong)要(yao)求(qiu)介電(dian)常數(shu)(shu)高，這樣才能在有(you)限體(ti)積下容(rong)納更(geng)高的(de)容(rong)量，電(dian)阻(zu)為什么(me)比電(dian)容(rong)個頭要(yao)小(xiao)，歸根結底是介電(dian)常數(shu)(shu)高啊!  

2、薄銅箔通過大(da)電流(liu)情況下溫(wen)升較小，這(zhe)對于散熱和元件壽命都是(shi)(shi)有很大(da)好(hao)(hao)處(chu)的(de)，數字集(ji)成電路中銅線寬度小于0.3cm也是(shi)(shi)這(zhe)個道理(li)。制作(zuo)精良的(de)FPC成品板非常均勻，光澤柔(rou)和(因(yin)為表面刷(shua)上阻焊劑)，鋰離子電池正極(ji)材(cai)料(liao)，這(zhe)個用肉眼能(neng)看出(chu)來，但要光看覆銅基板能(neng)看出(chu)好(hao)(hao)壞的(de)人卻不多，除非你是(shi)(shi)廠里經(jing)驗豐富的(de)品檢。
