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(nei)么在給電路板通(tong)電前(qian)， 一定(ding)要仔細檢(jian)查電源電路是否正常(chang)， 在確(que)保不會引起(qi)二次損傷(shang)后再通(tong)電。

2、通殺法(fa)：將所有(you)的元(yuan)器件都檢測一遍(bian)，直至找到有(you)問題(ti)的元(yuan)件，達到修(xiu)復(fu)的目的。

3、對比法：通過(guo)和好板的(de)狀(zhuang)態對比達(da)到查出故障的(de)目(mu)的(de)，通過(guo)對比兩塊(kuai)板的(de)各節點的(de)曲線來發現(xian)異常。

4、狀(zhuang)態(tai)法：檢(jian)查各元(yuan)器件正(zheng)常工(gong)作(zuo)的時狀(zhuang)態(tai)，如(ru)果某元(yuan)器件工(gong)作(zuo)時的狀(zhuang)態(tai)與正(zheng)常狀(zhuang)態(tai)不符合(he)，則(ze)該器件或者其受影(ying)響(xiang)的部件有問(wen)題。

5、搭(da)電路法(fa)：即動(dong)手制作(zuo)一個(ge)電路，該電路在裝上(shang)被沒(mei)的(de)集成電路后(hou)可(ke)以工作(zuo)，從而驗(yan)證被測集成電路質量的(de)方法(fa)。

6、原理(li)(li)分(fen)析法：分(fen)析一塊板的(de)工作原理(li)(li)，知(zhi)道其原理(li)(li)圖的(de)東(dong)西維修起來(lai)異常的(de)簡單。
