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， 那么在(zai)給電(dian)(dian)路(lu)板通電(dian)(dian)前， 一定要(yao)仔細檢查電(dian)(dian)源電(dian)(dian)路(lu)是否正常， 在(zai)確(que)保不(bu)會引起二次(ci)損(sun)傷后再通電(dian)(dian)。

2、通(tong)殺法：將所有(you)的元(yuan)器(qi)件都檢測一遍，直至找到有(you)問題的元(yuan)件，達到修復的目的。

3、對比(bi)法：通過和好板的狀態對比(bi)達到查出故障的目的，通過對比(bi)兩塊板的各節(jie)點(dian)的曲線來發現(xian)異常。

4、狀態(tai)法(fa)：檢(jian)查各元(yuan)器(qi)件正常(chang)工(gong)作(zuo)的時狀態(tai)，如果某元(yuan)器(qi)件工(gong)作(zuo)時的狀態(tai)與正常(chang)狀態(tai)不符合，則該器(qi)件或(huo)者其受影響(xiang)的部件有問題。

5、搭電(dian)路(lu)法(fa)：即動手制(zhi)作一個電(dian)路(lu)，該電(dian)路(lu)在裝上被(bei)沒(mei)的集成電(dian)路(lu)后可以(yi)工作，從而驗證(zheng)被(bei)測(ce)集成電(dian)路(lu)質(zhi)量的方(fang)法(fa)。

6、原理(li)分析(xi)法：分析(xi)一塊板(ban)的工作原理(li)，知道(dao)其原理(li)圖的東西維修起來異常(chang)的簡(jian)單。
