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(bei)燒過， 那么在給電路板通(tong)電前， 一定要仔細檢查電源電路是否正常， 在確保不會引起(qi)二(er)次(ci)損傷后(hou)再通(tong)電。

2、通殺(sha)法：將所有(you)的(de)元(yuan)器件都檢測一(yi)遍，直至找到(dao)有(you)問(wen)題的(de)元(yuan)件，達到(dao)修(xiu)復的(de)目的(de)。

3、對比(bi)法：通過和好板的狀態對比(bi)達到查(cha)出故障(zhang)的目的，通過對比(bi)兩塊板的各節點(dian)的曲線來(lai)發現異常。

4、狀(zhuang)態(tai)法：檢查(cha)各(ge)元器(qi)件(jian)(jian)正常(chang)工作(zuo)的(de)(de)時狀(zhuang)態(tai)，如果某元器(qi)件(jian)(jian)工作(zuo)時的(de)(de)狀(zhuang)態(tai)與(yu)正常(chang)狀(zhuang)態(tai)不符合(he)，則該器(qi)件(jian)(jian)或者其受(shou)影響(xiang)的(de)(de)部(bu)件(jian)(jian)有(you)問題(ti)。

5、搭電(dian)(dian)路(lu)法(fa)：即動(dong)手制作一個(ge)電(dian)(dian)路(lu)，該(gai)電(dian)(dian)路(lu)在裝上被(bei)沒的集(ji)成電(dian)(dian)路(lu)后可以工(gong)作，從而(er)驗證被(bei)測集(ji)成電(dian)(dian)路(lu)質量的方法(fa)。

6、原理(li)(li)分析法：分析一塊板的工作原理(li)(li)，知道其原理(li)(li)圖的東西維修起來異(yi)常的簡單。
