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(dian)路板(ban)通(tong)電(dian)前， 一定要仔(zi)細檢查電(dian)源電(dian)路是否正(zheng)常， 在確保不(bu)會引起二(er)次損傷(shang)后再(zai)通(tong)電(dian)。

2、通殺法：將(jiang)所有的(de)(de)元(yuan)器件(jian)(jian)都檢(jian)測一遍，直至(zhi)找到有問題(ti)的(de)(de)元(yuan)件(jian)(jian)，達到修復的(de)(de)目的(de)(de)。

3、對比法：通過(guo)和好板(ban)的狀(zhuang)態對比達(da)到查出故障(zhang)的目的，通過(guo)對比兩塊板(ban)的各節點的曲線來發現異常。

4、狀態法：檢查(cha)各元(yuan)器(qi)件(jian)正常工作的(de)時(shi)狀態，如(ru)果某元(yuan)器(qi)件(jian)工作時(shi)的(de)狀態與(yu)正常狀態不(bu)符合，則該器(qi)件(jian)或者其受(shou)影響的(de)部件(jian)有問題。

5、搭電路(lu)法(fa)：即(ji)動手制作一個(ge)電路(lu)，該電路(lu)在裝上被沒的集成電路(lu)后可以工(gong)作，從而(er)驗證(zheng)被測(ce)集成電路(lu)質量的方法(fa)。

6、原理分析(xi)法：分析(xi)一塊板(ban)的工(gong)作原理，知(zhi)道其原理圖的東西維修起來(lai)異常的簡單。
