3)交流工作電壓測(cè)試法
用帶有dB檔的萬(wàn)能表,對(duì)IC進(jìn)行交流電壓近似值的測(cè)量.若沒(méi)有dB
檔,則可在正表筆串入一只0.1-0.5μF隔離直流電容.該方法適用
于工作頻率比較低的IC.但要注意這些信號(hào)將受固有頻率,波形不
同而不同.所以所測(cè)數(shù)據(jù)為近似值,僅供參考.
4)總電流測(cè)量法
通過(guò)測(cè)IC電源的總電流,來(lái)判別IC的好壞.由于IC內(nèi)部大多數(shù)為直
流耦合,IC損壞時(shí)(如PN結(jié)擊穿或開(kāi)路)會(huì)引起后級(jí)飽和與截止,使
總電流發(fā)生變化.所以測(cè)總電流可判斷IC的好壞.在線測(cè)得回路電
阻上的電壓,即可算出電流值來(lái).
以上檢測(cè)方法,各有利弊.在實(shí)際應(yīng)用中將這些方法結(jié)合來(lái)運(yùn)用.運(yùn)用好了
就能維修好各種電路板。
