3)交流工作電壓測試法
用帶有dB檔的萬能表,對IC進行交流電壓近似值的測量.若沒有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.但要注意這些信號將受固有頻率,波形不
同而不同.所以所測數據為近似值,僅供參考.
4)總電流測量法
通過測IC電源的總電流,來判別IC的好壞.由于IC內部大多數為直
流耦合,IC損壞時(如PN結擊穿或開路)會引起后級飽和與截止,使
總電流發生變化.所以測總電流可判斷IC的好壞.在線測得回路電
阻上的電壓,即可算出電流值來.
以上檢測方法,各有利弊.在實際應用中將這些方法結合來運用.運用好了
就能維修好各種電路板。
