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(guo)， 那(nei)么在給電路(lu)板通電前， 一定要仔(zi)細檢查電源電路(lu)是(shi)否正常， 在確保(bao)不會引起二次損傷后再(zai)通電。

2、通殺法：將所有的(de)(de)元(yuan)器件都檢測一遍，直(zhi)至找(zhao)到有問題的(de)(de)元(yuan)件，達到修復(fu)的(de)(de)目(mu)的(de)(de)。

3、對(dui)比(bi)法：通過和好板的(de)狀(zhuang)態對(dui)比(bi)達到查出(chu)故障(zhang)的(de)目的(de)，通過對(dui)比(bi)兩(liang)塊板的(de)各節點的(de)曲線來發(fa)現異(yi)常。

4、狀態(tai)(tai)法：檢(jian)查各元(yuan)器(qi)件正常工作的(de)時狀態(tai)(tai)，如果某元(yuan)器(qi)件工作時的(de)狀態(tai)(tai)與正常狀態(tai)(tai)不符(fu)合，則該器(qi)件或者其受影響(xiang)的(de)部件有問題。

5、搭電(dian)路法：即動手制(zhi)作一個(ge)電(dian)路，該電(dian)路在裝上被(bei)沒的集成(cheng)電(dian)路后可以工(gong)作，從而驗(yan)證(zheng)被(bei)測集成(cheng)電(dian)路質量的方法。

6、原理分析法：分析一塊板的(de)(de)工作原理，知道其原理圖(tu)的(de)(de)東西維修起來異常(chang)的(de)(de)簡(jian)單。
