2)直流工作电压的测量法
测得IC芯片各脚直流电压与正常值相比即可.但也要注意:
(a)万能表要有足够大的内阻,数字表为;
(b)各电位器旋到中间位置;
(c)表笔或探头要采取防滑措施,可用自行车气门芯套在笔头上,
并应长出笔尖约5mm;
(d)当测量值与正常值不相符时,应根据该引脚电压,对IC芯片正
常值有无影响以及其它引脚电压的相应变化进行分析;
(e)IC芯片引脚电压会受外围元器件的影响.当外围有漏电,短路,
开路或变质等;
(f)IC芯片部分引脚异常时,则从偏离大的入手.先查外围元器件,
若无故障,则IC芯片损坏;
(g)对工作时有动态信号的电路板,有无信号IC芯片引脚电压是不
同的.但若变化不正常则IC芯片可能已坏;
(h)对多种工作方式的设备,在不同工作方式时IC脚的电压是不同
的.
