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(me)在給電(dian)(dian)(dian)路(lu)板通電(dian)(dian)(dian)前， 一定要(yao)仔細檢查(cha)電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)是否(fou)正常， 在確保不會引起二次損(sun)傷(shang)后再通電(dian)(dian)(dian)。

2、通殺(sha)法：將所有的(de)元器件(jian)都檢測一遍，直(zhi)至找到有問題的(de)元件(jian)，達(da)到修復的(de)目的(de)。

3、對(dui)比(bi)法：通過和好板的(de)狀態對(dui)比(bi)達到查出故(gu)障(zhang)的(de)目的(de)，通過對(dui)比(bi)兩(liang)塊板的(de)各節點(dian)的(de)曲(qu)線來(lai)發現異(yi)常。

4、狀(zhuang)態(tai)法：檢查(cha)各元器件正(zheng)常(chang)工作的時狀(zhuang)態(tai)，如果某元器件工作時的狀(zhuang)態(tai)與正(zheng)常(chang)狀(zhuang)態(tai)不符(fu)合，則該器件或者其受影(ying)響的部件有問題。

5、搭電(dian)路法(fa)：即動(dong)手制作一個電(dian)路，該電(dian)路在裝上被沒(mei)的(de)集(ji)成(cheng)電(dian)路后可以工作，從而驗證被測(ce)集(ji)成(cheng)電(dian)路質(zhi)量的(de)方法(fa)。

6、原(yuan)(yuan)(yuan)理分析法：分析一(yi)塊板的(de)工作原(yuan)(yuan)(yuan)理，知(zhi)道(dao)其(qi)原(yuan)(yuan)(yuan)理圖的(de)東西維(wei)修起來異常的(de)簡單。
