.组合代换
组合代换就是把同一型号的多块IC内部未受损的电路部分,重新组合成一块完整的IC,用以代替功能不良的IC的方法。对买不到原配IC的情况下是十分适用的。但要求所利用IC内部完好的电路一定要有接口引出脚。
非直接代换关键是要查清楚互相代换的两种IC的基本电参数、内部等效电路、各引脚的功能、IC与外部元件之间连接关系的资料。实际操作时予以注意:
⑴集成电路引脚的编号顺序,切勿接错;
⑵为适应代换后的IC的特点,与其相连的外围电路的元件要作相应的改变;
⑶电源电压要与代换后的IC相符,如果原电路中电源电压高,应设法降压;电压低,要看代换IC能否工作。
⑷代换以后要测量IC的静态工作电流,如电流远大于正常值,则说明电路可能产生自激,这时须进行去耦、调整。若增益与原来有所差别,可调整反馈电阻阻值;
⑸代换后IC的输入、输出阻抗要与原电路相匹配;检查其驱动能力。
⑹在改动时要充分利用原电路板上的脚孔和引线,外接引线要求整齐,避免前后交叉,以便检查和防止电路自激,特别是防止高频自激;
[7]在通电前电源Vcc回路里再串接一直流电流表,降压电阻阻值由大到小观察集成电路总电流的变化是否正常。
