描述
現(xiàn)以匯能IC在線維修測(cè)試儀檢測(cè)為例,介紹其具體方法。我們都知道,集成塊使用時(shí),總有一個(gè)引腳與印制電路板上的“地”線是焊通的,在電路中稱(chēng)之為接地腳。由于電路板維修內(nèi)部都采用直接耦合,因此,集成塊的其它引腳與接地腳之間都存在著確定的直流電阻,這種確定的直流電阻稱(chēng)為該腳內(nèi)部等效直流電阻,簡(jiǎn)稱(chēng)R內(nèi)。當(dāng)我們拿到一塊新的集成塊時(shí),可通過(guò)用萬(wàn)用表測(cè)量各引腳的內(nèi)部等效直流電阻來(lái)判斷其好壞,若各引腳的內(nèi)部等效電阻R內(nèi)與標(biāo)準(zhǔn)值相符,說(shuō)明這塊集成塊是好的,反之若與標(biāo)準(zhǔn)值相差過(guò)大,說(shuō)明集成塊內(nèi)部損壞。
