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(nei)么在給電路(lu)板通(tong)電前， 一定要(yao)仔細檢查(cha)電源電路(lu)是否正常， 在確保不會引(yin)起二次損傷(shang)后再通(tong)電。

2、通殺法(fa)：將所有的(de)元器件都檢測一遍，直至找到有問題的(de)元件，達到修復的(de)目的(de)。

3、對(dui)比(bi)(bi)法：通過和好板(ban)的狀態對(dui)比(bi)(bi)達到查出故障的目的，通過對(dui)比(bi)(bi)兩塊板(ban)的各(ge)節點的曲線來發(fa)現異常。

4、狀態(tai)法：檢查(cha)各(ge)元器(qi)件(jian)正常工作(zuo)的時狀態(tai)，如果某元器(qi)件(jian)工作(zuo)時的狀態(tai)與(yu)正常狀態(tai)不符合(he)，則該器(qi)件(jian)或者其受影(ying)響的部件(jian)有問題。

5、搭電(dian)路法(fa)(fa)：即動手制作一個電(dian)路，該電(dian)路在裝(zhuang)上(shang)被沒的集(ji)成電(dian)路后(hou)可以工作，從而驗證被測集(ji)成電(dian)路質量(liang)的方法(fa)(fa)。

6、原理分(fen)析法：分(fen)析一塊板(ban)的(de)工作原理，知道(dao)其原理圖的(de)東西(xi)維(wei)修起來異常的(de)簡單。
