高頻(pin)變(bian)壓(ya)器(qi)包銅箔的繞(rao)制方法(fa)

1、銅箔繞制工法

1)銅(tong)(tong)箔的(de)(de)種類及在(zai)變(bian)壓器中的(de)(de)作(zuo)用(yong)；我們以銅(tong)(tong)箔的(de)(de)外(wai)形分有裸(luo)銅(tong)(tong)各背膠(jiao)兩種：銅(tong)(tong)箔表面有覆(fu)蓋一層(ceng)Tape的(de)(de)為(wei)背膠(jiao)，反之(zhi)為(wei)裸(luo)銅(tong)(tong)；以在(zai)變(bian)壓器中的(de)(de)位置不(bu)同(tong)分為(wei)內(nei)銅(tong)(tong)和外(wai)銅(tong)(tong)。裸(luo)銅(tong)(tong)一般(ban)用(yong)于(yu)變(bian)壓器的(de)(de)外(wai)銅(tong)(tong)。銅(tong)(tong)箔在(zai)變(bian)壓器中一般(ban)起屏蔽作(zuo)用(yong)，主要是減小漏感，激磁電流，在(zai)繞組所(suo)通過(guo)的(de)(de)電流過(guo)高時，T4420W銅(tong)(tong)箔哪里好，取(qu)代銅(tong)(tong)線(xian)，起導體的(de)(de)作(zuo)用(yong)。

2)銅箔的加工。

銅(tong)箔(bo)種(zhong)類(lei)及銅(tong)箔(bo)的特(te)點？銅(tong)箔(bo)的種(zhong)類(lei)有哪些呢？要想知(zhi)道(dao)銅(tong)箔(bo)的種(zhong)類(lei)，我(wo)們還是先了解(jie)下什么是銅(tong)箔(bo)吧。銅(tong)箔(bo)其實(shi)是一種(zhong)陰質性電解(jie)材料。

銅(tong)箔(bo)是(shi)沉淀于電(dian)(dian)路板基(ji)底(di)層(ceng)上(shang)的(de)(de)一層(ceng)薄(bo)的(de)(de)、連續的(de)(de)金屬(shu)箔(bo)。銅(tong)箔(bo)作(zuo)為一種(zhong)PCB的(de)(de)導電(dian)(dian)體，容易粘(zhan)合于絕(jue)緣(yuan)層(ceng)，接(jie)受印刷保護層(ceng)，腐(fu)蝕后形成電(dian)(dian)路圖樣。銅(tong)箔(bo)具(ju)有(you)低表(biao)面(mian)氧氣特性(xing)(xing)，可以附著與各種(zhong)不同基(ji)材，如(ru)金屬(shu)，溫州T4420W銅(tong)箔(bo)，絕(jue)緣(yuan)材料等，擁有(you)較(jiao)寬的(de)(de)溫度使用(yong)范圍。主要應用(yong)于電(dian)(dian)磁屏蔽及抗靜電(dian)(dian)，將導電(dian)(dian)銅(tong)箔(bo)置(zhi)于襯底(di)面(mian)，結(jie)合金屬(shu)基(ji)材，具(ju)有(you)優良的(de)(de)導通性(xing)(xing)，并(bing)提(ti)供電(dian)(dian)磁屏蔽的(de)(de)效果。了(le)(le)(le)解了(le)(le)(le)銅(tong)箔(bo)的(de)(de)定義、特性(xing)(xing)和用(yong)途，我們(men)馬上(shang)來了(le)(le)(le)解下(xia)的(de)(de)種(zhong)類吧。

銅箔(bo)(bo)種類及銅箔(bo)(bo)的(de)特點？銅箔(bo)(bo)的(de)種類有：

1、按厚(hou)(hou)度可以(yi)分為厚(hou)(hou)銅箔(大(da)于(yu)(yu)70μm)、常規厚(hou)(hou)度銅箔(大(da)于(yu)(yu)18μm而(er)小于(yu)(yu)70μm)、薄(bo)銅箔(大(da)于(yu)(yu)12μm而(er)小于(yu)(yu)18μm)、超薄(bo)銅箔(小于(yu)(yu)12μm)；

銅(tong)(tong)箔種類及(ji)銅(tong)(tong)箔的特點？壓延銅(tong)(tong)箔和(he)電解銅(tong)(tong)箔的區別：

電(dian)解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)是(shi)利用電(dian)流將(jiang)硫酸銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)溶液中(zhong)的(de)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)離子析出而成(cheng)，再經粗化處理(li)(li)等制程后完成(cheng)。壓(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)則是(shi)用銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)錠碾(nian)壓(ya)而成(cheng)，T4420W銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)箔(bo)(bo)推(tui)薦(jian)，再經鍛火、粗化處理(li)(li)等制程。相對電(dian)解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，壓(ya)延(yan)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)生產比較(jiao)困難，全世界目(mu)前也只有(you)三家可大量產（據(ju)有(you)關報告得知），T4420W銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)箔(bo)(bo)代理(li)(li)商(shang)，延(yan)展性較(jiao)好（可達30％以上，而電(dian)解(jie)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)好的(de)SHTE型也只有(you)15％－20％），主要(yao)應用在FPC、筆記(ji)本電(dian)腦、平板電(dian)腦、打印機等需要(yao)屏蔽(bi)的(de)地方。
