面對形形色色的電源適配器你(ni)對此了解(jie)多少?什(shen)么(me)是電(dian)源適配(pei)器?壞了要怎(zen)樣維修?今天我們(men)和(he)電(dian)源適配(pei)器廠(chang)家一起來(lai)看一下!

　　什么是電源適配器?

　　電(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)是(shi)小型便攜式(shi)(shi)電(dian)(dian)子設備(bei)及電(dian)(dian)子電(dian)(dian)器(qi)(qi)(qi)的供電(dian)(dian)電(dian)(dian)源(yuan)(yuan)變換(huan)設備(bei)，一般由外(wai)殼、電(dian)(dian)源(yuan)(yuan)變壓器(qi)(qi)(qi)和整流電(dian)(dian)路組成，按(an)(an)其輸入(ru)類型可分(fen)為(wei)交流電(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)和直流電(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi);按(an)(an)連接方(fang)式(shi)(shi)可分(fen)為(wei)插墻(qiang)式(shi)(shi)電(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)和桌面式(shi)(shi)電(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)。廣泛(fan)配(pei)套于電(dian)(dian)話子母機(ji)、游(you)戲機(ji)、語言(yan)復讀機(ji)、隨身聽(ting)、筆記(ji)本計算機(ji)、蜂窩電(dian)(dian)話等(deng)設備(bei)中。

　　電源適配器壞了要怎樣維修?

　　1.如果(guo)原裝(zhuang)適配(pei)器有問題，無法維(wei)修或者(zhe)來不及修，可(ke)以(yi)先使用(yong)其它(ta)適配(pei)器替代(dai)。只要輸出(chu)電(dian)壓(ya)和(he)功率大致相(xiang)當既(ji)可(ke)。筆(bi)記本電(dian)腦電(dian)源(yuan)適配(pei)器內部(bu)還(huan)有穩壓(ya)電(dian)路撐著，不要太過(guo)于擔心輸出(chu)電(dian)壓(ya)不匹配(pei)的(de)問題。而(er)在維(wei)修時(shi)，第一步需要做的(de)就是(shi)工(gong)具(ju)準備(bei)。我們(men)需要用(yong)萬(wan)用(yong)表(biao)、螺絲(si)刀、焊(han)接(jie)工(gong)具(ju)。

　　2.電(dian)(dian)(dian)源(yuan)適配(pei)器上有(you)四個塑料帽(mao)，盡可(ke)能不要破(po)壞適配(pei)器外(wai)(wai)殼(ke)，外(wai)(wai)殼(ke)破(po)壞后，會(hui)出現電(dian)(dian)(dian)磁輻射加強等問(wen)題，影響機器穩定。如(ru)果(guo)外(wai)(wai)殼(ke)破(po)壞，盡量(liang)補修(xiu)。拆卸(xie)過程如(ru)果(guo)外(wai)(wai)置電(dian)(dian)(dian)源(yuan)不供電(dian)(dian)(dian)，這時可(ke)以插上電(dian)(dian)(dian)池試試，如(ru)果(guo)機器可(ke)以正常啟動，就有(you)可(ke)能是電(dian)(dian)(dian)源(yuan)線(xian)或(huo)者適配(pei)器有(you)問(wen)題。打(da)開外(wai)(wai)觀，打(da)開屏(ping)蔽層后，最好(hao)是首先檢查焊腳，肉眼(yan)觀察即可(ke)。電(dian)(dian)(dian)路時斷時續，一(yi)般是接(jie)觸不良(liang)。然后用(yong)萬(wan)用(yong)表檢測，查明(ming)電(dian)(dian)(dian)源(yuan)線(xian)是否(fou)有(you)問(wen)。

　　3.在測試過程(cheng)中(zhong)，如(ru)果(guo)發(fa)現電(dian)阻引腳被虛焊(han)了，就(jiu)用焊(han)接工(gong)具補焊(han)上去，將電(dian)源適配(pei)器安裝(zhuang)好(hao)，開機測試、問(wen)(wen)題解決(jue)。需(xu)要(yao)(yao)注意(yi)的(de)(de)是(shi)，如(ru)果(guo)在檢測過程(cheng)中(zhong)，遇到某個(ge)電(dian)容(rong)(rong)有(you)問(wen)(wen)題，可(ke)以購買一(yi)(yi)個(ge)型(xing)號和容(rong)(rong)量一(yi)(yi)樣的(de)(de)電(dian)容(rong)(rong)，把(ba)有(you)問(wen)(wen)題的(de)(de)電(dian)容(rong)(rong)取焊(han)下來，將新電(dian)容(rong)(rong)焊(han)上去即可(ke)。如(ru)果(guo)發(fa)現IC電(dian)源線有(you)問(wen)(wen)題，那么也(ye)可(ke)以按(an)照同(tong)樣的(de)(de)方法(fa)解決(jue)。當然(ran)由于(yu)IC芯片絕對(dui)是(shi)電(dian)源適配(pei)器中(zhong)最重要(yao)(yao)的(de)(de)電(dian)子(zi)元器件之(zhi)一(yi)(yi)，電(dian)容(rong)(rong)過于(yu)復雜(za)。

　　4.由于現在的電(dian)源適配(pei)器已經大量采(cai)用貼片元(yuan)件(jian)(jian)，一(yi)旦元(yuan)件(jian)(jian)出(chu)了(le)(le)問題，維(wei)修的難度就(jiu)更加大了(le)(le)。電(dian)源適配(pei)器的功率(lv)(lv)一(yi)天一(yi)天增大，對電(dian)子(zi)元(yuan)件(jian)(jian)的考(kao)驗也是越(yue)來越(yue)大，如果(guo)電(dian)源適配(pei)器采(cai)用的電(dian)子(zi)元(yuan)件(jian)(jian)質(zhi)量不(bu)過關、PCB布(bu)線(xian)不(bu)當(dang)，就(jiu)很有可能加大故(gu)障概率(lv)(lv)。因此選(xuan)購(gou)一(yi)個質(zhi)量好的電(dian)源適配(pei)器很重(zhong)要!

　　5.檢查(cha)電(dian)容電(dian)阻(zu)電(dian)感有無問題，如電(dian)容出(chu)現鼓包，最好及(ji)時更(geng)換以免(mian)留下隱患。
