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(guo), 那么在(zai)給電(dian)路板通(tong)電(dian)前, 一定要仔(zi)細檢查電(dian)源(yuan)電(dian)路是否正常, 在(zai)確保不會引起(qi)二次損(sun)傷(shang)后再(zai)通(tong)電(dian)。
2、通殺(sha)法:將(jiang)所有的(de)元器件(jian)都檢測一遍,直至找到(dao)有問(wen)題的(de)元件(jian),達到(dao)修復(fu)的(de)目的(de)。
3、對比法:通(tong)過和好(hao)板的(de)狀(zhuang)態對比達到(dao)查出故(gu)障(zhang)的(de)目的(de),通(tong)過對比兩塊板的(de)各節(jie)點的(de)曲線來發現(xian)異常。
4、狀態(tai)法(fa):檢查各(ge)元器(qi)件(jian)正常(chang)工作的時(shi)狀態(tai),如果某元器(qi)件(jian)工作時(shi)的狀態(tai)與正常(chang)狀態(tai)不(bu)符合(he),則該器(qi)件(jian)或者(zhe)其受影響(xiang)的部件(jian)有問題。
5、搭電(dian)路法(fa):即動手制作(zuo)一個電(dian)路,該電(dian)路在裝上被(bei)沒的(de)集成(cheng)電(dian)路后可以工作(zuo),從而驗證(zheng)被(bei)測集成(cheng)電(dian)路質量的(de)方法(fa)。
6、原理分析(xi)法:分析(xi)一塊板的(de)工作原理,知道其原理圖的(de)東西維(wei)修起(qi)來(lai)異常(chang)的(de)簡單。
