.組合代換
組合代換就是把同一型號(hào)的多塊IC內(nèi)部未受損的電路部分，重新組合成一塊完整的IC，用以代替功能不良的IC的方法。對(duì)買不到原配IC的情況下是十分適用的。但要求所利用IC內(nèi)部完好的電路一定要有接口引出腳。
非直接代換關(guān)鍵是要查清楚互相代換的兩種IC的基本電參數(shù)、內(nèi)部等效電路、各引腳的功能、IC與外部元件之間連接關(guān)系的資料。實(shí)際操作時(shí)予以注意：
⑴集成電路引腳的編號(hào)順序，切勿接錯(cuò)；
⑵為適應(yīng)代換后的IC的特點(diǎn)，與其相連的外圍電路的元件要作相應(yīng)的改變；
⑶電源電壓要與代換后的IC相符，如果原電路中電源電壓高，應(yīng)設(shè)法降壓；電壓低，要看代換IC能否工作。
⑷代換以后要測(cè)量IC的靜態(tài)工作電流，如電流遠(yuǎn)大于正常值，則說(shuō)明電路可能產(chǎn)生自激，這時(shí)須進(jìn)行去耦、調(diào)整。若增益與原來(lái)有所差別，可調(diào)整反饋電阻阻值；
⑸代換后IC的輸入、輸出阻抗要與原電路相匹配；檢查其驅(qū)動(dòng)能力。
⑹在改動(dòng)時(shí)要充分利用原電路板上的腳孔和引線,外接引線要求整齊，避免前后交叉，以便檢查和防止電路自激，特別是防止高頻自激;
[7]在通電前電源Vcc回路里再串接一直流電流表，降壓電阻阻值由大到小觀察集成電路總電流的變化是否正常。
