描述
測(cè)量時(shí)有一點(diǎn)必須注意,由于集成塊內(nèi)部有大量的三極管,二極管等非線性元件,在測(cè)量中單測(cè)得一個(gè)阻值還不能判斷其好壞,必須互換表筆再測(cè)一次,獲得正反向兩個(gè)阻值。只有當(dāng)R內(nèi)正反向阻值都符合標(biāo)準(zhǔn),才能斷定該集成塊完好。在實(shí)際修理中,通常采用在路測(cè)量。先測(cè)量其引腳電壓,如果電壓異常,可斷開(kāi)引腳連線測(cè)接線端電壓,以判斷電壓變化是外圍元件引起,還是集成塊內(nèi)部引起。也可以采用測(cè)外部電路到地之間的直流等效電阻(稱R外)來(lái)判斷,通常在電路中測(cè)得的集成塊某引腳與接地腳之間的直流電阻(在路電阻),實(shí)際是R內(nèi)與R外并聯(lián)的總直流等效電阻。在修理中常將在路電壓與在路電阻的測(cè)量方法結(jié)合使用。有時(shí)在路電壓和在路電阻偏離標(biāo)準(zhǔn)值,并不一定是集成塊損壞,而是有關(guān)外圍元件損壞,使R外不正常,從而造成在路電壓和在路電阻的異常。這時(shí)便只能測(cè)量集成塊內(nèi)部直流等效電阻,才能判定集成塊是否損壞。
