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)在給電(dian)路板通(tong)(tong)電(dian)前(qian)， 一(yi)定要仔細檢查電(dian)源電(dian)路是否正常， 在確(que)保不會引起二次損傷后再(zai)通(tong)(tong)電(dian)。

2、通(tong)殺(sha)法：將所有(you)的(de)元(yuan)器(qi)件都檢測一遍(bian)，直至(zhi)找到(dao)有(you)問(wen)題的(de)元(yuan)件，達(da)到(dao)修(xiu)復的(de)目(mu)的(de)。

3、對(dui)比(bi)(bi)法：通(tong)過(guo)和(he)好板的(de)(de)(de)狀(zhuang)態對(dui)比(bi)(bi)達到查出故障的(de)(de)(de)目的(de)(de)(de)，通(tong)過(guo)對(dui)比(bi)(bi)兩(liang)塊板的(de)(de)(de)各節(jie)點(dian)的(de)(de)(de)曲線來發現異(yi)常。

4、狀態(tai)法(fa)：檢查各元(yuan)器件正常工作(zuo)的時(shi)狀態(tai)，如果某元(yuan)器件工作(zuo)時(shi)的狀態(tai)與正常狀態(tai)不(bu)符合，則該器件或者(zhe)其受影響(xiang)的部(bu)件有問題。

5、搭(da)電(dian)路法(fa)：即動手制(zhi)作一個(ge)電(dian)路，該(gai)電(dian)路在裝上被沒的(de)集成電(dian)路后可以(yi)工作，從而驗證被測集成電(dian)路質量(liang)的(de)方(fang)法(fa)。

6、原理(li)(li)分析法：分析一塊(kuai)板(ban)的(de)(de)工作原理(li)(li)，知(zhi)道(dao)其原理(li)(li)圖的(de)(de)東西維修起來異常的(de)(de)簡單。
