電路板維修方法

1、觀察法：當我們拿到一塊待維修的電路板時， 首先對它的外觀進行仔細的觀察。如果某品牌電路板被燒過， 那么(me)在(zai)給電路板通電前， 一定要(yao)仔(zi)細檢查電源電路是否正常， 在(zai)確保不會引起二次損傷后(hou)再(zai)通電。

2、通殺法：將所有的元器件都(dou)檢測(ce)一(yi)遍，直至找到有問題的元件，達到修復的目(mu)的。

3、對(dui)比(bi)法(fa)：通(tong)過和好板(ban)的(de)狀態對(dui)比(bi)達到查出故(gu)障的(de)目的(de)，通(tong)過對(dui)比(bi)兩(liang)塊板(ban)的(de)各節點的(de)曲線來發現異(yi)常。

4、狀態法：檢查(cha)各(ge)元器(qi)(qi)件正(zheng)常工(gong)(gong)作的時狀態，如果某元器(qi)(qi)件工(gong)(gong)作時的狀態與正(zheng)常狀態不符(fu)合(he)，則該(gai)器(qi)(qi)件或者(zhe)其受(shou)影響的部件有問題。

5、搭電路法：即動手制作一(yi)個(ge)電路，該電路在裝上被沒的集成(cheng)電路后(hou)可以工作，從而(er)驗(yan)證被測集成(cheng)電路質(zhi)量的方法。

6、原理(li)分(fen)析法：分(fen)析一(yi)塊板(ban)的工作原理(li)，知道(dao)其原理(li)圖的東(dong)西維修起來(lai)異常的簡單(dan)。
