在正(zheng)規的工業(ye)化(hua)生(sheng)產中，都(dou)設有專門的元器(qi)件(jian)(jian)(jian)篩(shai)選(xuan)老化(hua)檢(jian)測車間(jian)，備有許多(duo)通用(yong)(yong)和(he)專用(yong)(yong)的篩(shai)選(xuan)檢(jian)測裝備和(he)儀器(qi)，但對(dui)于業(ye)余電子(zi)(zi)(zi)愛(ai)(ai)好者來說，不可能具備這些(xie)條件(jian)(jian)(jian)，即使如此，也絕不可以放棄對(dui)元器(qi)件(jian)(jian)(jian)的篩(shai)選(xuan)和(he)檢(jian)測工作，因為許多(duo)電子(zi)(zi)(zi)愛(ai)(ai)好者所(suo)用(yong)(yong)的電子(zi)(zi)(zi)元器(qi)件(jian)(jian)(jian)是郵購來的，其中有正(zheng)品(pin)，也有次品(pin)，更(geng)多(duo)的是業(ye)余品(pin)或利用(yong)(yong)品(pin)，如在安裝之(zhi)前不對(dui)它們進(jin)行(xing)篩(shai)選(xuan)檢(jian)測，一旦焊入(ru)印刷電路板(ban)上，發(fa)現電路不能正(zheng)常工作，再去(qu)檢(jian)查，不僅浪費很多(duo)時間(jian)和(he)精力，而(er)且拆(chai)來拆(chai)去(qu)很容易損(sun)壞元件(jian)(jian)(jian)及印刷電路板(ban)。

一(yi)(yi)般電(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)廠家采用(yong)的(de)(de)(de)老化(hua)(hua)篩選項目(mu)一(yi)(yi)般有(you)：高(gao)(gao)溫(wen)(wen)存(cun)儲老化(hua)(hua)；高(gao)(gao)低(di)(di)溫(wen)(wen)循環(huan)老化(hua)(hua)；高(gao)(gao)低(di)(di)溫(wen)(wen)沖擊(ji)老化(hua)(hua)和高(gao)(gao)溫(wen)(wen)功(gong)率老化(hua)(hua)等。其(qi)中高(gao)(gao)溫(wen)(wen)功(gong)率老化(hua)(hua)是給試驗(yan)的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)通電(dian)(dian)(dian)，模擬實(shi)際工(gong)作(zuo)條件(jian)(jian)，再加上＋80℃～＋180℃的(de)(de)(de)高(gao)(gao)溫(wen)(wen)經(jing)歷(li)幾個小時(shi)(shi)，它(ta)是一(yi)(yi)種(zhong)對(dui)(dui)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)多種(zhong)潛(qian)在(zai)故(gu)障都有(you)檢(jian)驗(yan)作(zuo)用(yong)的(de)(de)(de)有(you)效措(cuo)施，也(ye)是目(mu)前采用(yong)得最多的(de)(de)(de)一(yi)(yi)種(zhong)方(fang)(fang)法。對(dui)(dui)于(yu)(yu)業余愛好(hao)者來說，在(zai)單件(jian)(jian)電(dian)(dian)(dian)子(zi)(zi)制(zhi)作(zuo)過程中，是不太可(ke)能采取(qu)這些(xie)方(fang)(fang)法進行老化(hua)(hua)檢(jian)測的(de)(de)(de)，在(zai)大多數情況下，采用(yong)了自然(ran)(ran)老化(hua)(hua)的(de)(de)(de)方(fang)(fang)式。例如使用(yong)前將元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)存(cun)放一(yi)(yi)段時(shi)(shi)間，讓電(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)自然(ran)(ran)地經(jing)歷(li)夏季高(gao)(gao)溫(wen)(wen)和冬季低(di)(di)溫(wen)(wen)的(de)(de)(de)考驗(yan)，然(ran)(ran)后(hou)再來檢(jian)測它(ta)們的(de)(de)(de)電(dian)(dian)(dian)性能，看(kan)是否符(fu)合使用(yong)要求，優(you)存(cun)劣汰(tai)。對(dui)(dui)于(yu)(yu)一(yi)(yi)些(xie)急用(yong)的(de)(de)(de)電(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)，也(ye)可(ke)采用(yong)簡易電(dian)(dian)(dian)老化(hua)(hua)方(fang)(fang)式，用(yong)一(yi)(yi)臺輸出電(dian)(dian)(dian)壓(ya)可(ke)調的(de)(de)(de)脈動直流電(dian)(dian)(dian)源，使加在(zai)電(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)兩端的(de)(de)(de)電(dian)(dian)(dian)壓(ya)略高(gao)(gao)于(yu)(yu)元(yuan)(yuan)件(jian)(jian)額定值的(de)(de)(de)工(gong)作(zuo)電(dian)(dian)(dian)壓(ya)，調整(zheng)流過元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)的(de)(de)(de)電(dian)(dian)(dian)流強度，使其(qi)功(gong)率為1.5～2倍額定功(gong)率，通電(dian)(dian)(dian)幾分鐘甚至更長(chang)時(shi)(shi)間，利(li)用(yong)元(yuan)(yuan)器(qi)(qi)(qi)件(jian)(jian)自身的(de)(de)(de)特性而發熱升(sheng)溫(wen)(wen)，完成簡易老化(hua)(hua)過程。
