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(shao)過， 那么在給(gei)電(dian)(dian)路板通(tong)(tong)電(dian)(dian)前(qian)， 一定要仔(zi)細檢(jian)查電(dian)(dian)源(yuan)電(dian)(dian)路是否正常， 在確(que)保不(bu)會引起二次損傷后(hou)再通(tong)(tong)電(dian)(dian)。

2、通殺法：將所有的(de)(de)元器件都檢(jian)測一遍，直至找到有問題的(de)(de)元件，達到修復的(de)(de)目的(de)(de)。

3、對(dui)比法：通過(guo)和好(hao)板的狀態(tai)對(dui)比達到查出故障的目的，通過(guo)對(dui)比兩塊板的各節(jie)點的曲(qu)線來發現異常。

4、狀態法：檢查各元(yuan)器(qi)件(jian)正(zheng)常工(gong)作(zuo)的時狀態，如果某(mou)元(yuan)器(qi)件(jian)工(gong)作(zuo)時的狀態與正(zheng)常狀態不符合，則(ze)該(gai)器(qi)件(jian)或者其(qi)受(shou)影(ying)響的部件(jian)有問題(ti)。

5、搭電(dian)(dian)路(lu)法：即(ji)動手制(zhi)作(zuo)一個電(dian)(dian)路(lu)，該電(dian)(dian)路(lu)在裝上被沒的(de)集(ji)成電(dian)(dian)路(lu)后可以(yi)工作(zuo)，從而驗證被測集(ji)成電(dian)(dian)路(lu)質量的(de)方(fang)法。

6、原理分析(xi)法(fa)：分析(xi)一塊(kuai)板的工作原理，知道(dao)其(qi)原理圖的東西維修(xiu)起來(lai)異常的簡(jian)單。
