一 電(dian)路板維(wei)修的(de)一般順序

（1）首先，仔細觀(guan)察故(gu)障電路(lu)板的表面有(you)無(wu)明顯的故(gu)障痕跡。如：有(you)無(wu)燒焦(jiao)燒裂(lie)的集成IC或(huo)其它元件，線路(lu)板是否有(you)斷線開裂(lie)的痕跡。

（2）解故障發生(sheng)的過程，分析故障發生(sheng)的原因(yin)，推斷故障器件可能存在的部位。

（3）了(le)解和分析故障電(dian)路板的應用(yong)性質(zhi)，統計(ji)所用(yong)集(ji)成IC的種(zhong)類。

（4）確定具體故障器件(jian)，更換(huan)好(hao)的集成IC時，zui好(hao)先裝一個IC器件(jian)插座(zuo)試(shi)換(huan)。

（5）利(li)用(yong)各種檢(jian)(jian)測(ce)方法，按(an)照可(ke)能性大小的順序依次(ci)檢(jian)(jian)測(ce)，逐漸縮小故障的范圍。

（6）根據各類集成IC所處的位置、發生(sheng)故障的可(ke)能性(xing)大小排序。
