導電(dian)(dian)陽(yang)極(ji)絲測(ce)試(shi)（Conductiveanodicfilamenttest，簡稱(cheng)CAF）是(shi)(shi)(shi)電(dian)(dian)化學遷(qian)(qian)(qian)移(yi)的(de)(de)(de)(de)(de)其中(zhong)一種表現形(xing)式。它與表面(mian)樹狀生長(chang)的(de)(de)(de)(de)(de)區別：1.產生遷(qian)(qian)(qian)移(yi)的(de)(de)(de)(de)(de)金(jin)屬是(shi)(shi)(shi)銅，而(er)不是(shi)(shi)(shi)鉛或者錫；2.金(jin)屬絲是(shi)(shi)(shi)從陽(yang)極(ji)往陰極(ji)生長(chang)的(de)(de)(de)(de)(de)；3.金(jin)屬絲是(shi)(shi)(shi)由(you)金(jin)屬鹽組成(cheng)，而(er)不是(shi)(shi)(shi)中(zhong)性的(de)(de)(de)(de)(de)金(jin)屬原子組成(cheng)。焊盤中(zhong)的(de)(de)(de)(de)(de)銅金(jin)屬是(shi)(shi)(shi)金(jin)屬離(li)子的(de)(de)(de)(de)(de)主要(yao)來(lai)源，在(zai)陽(yang)極(ji)電(dian)(dian)化學生成(cheng)，并沿著樹脂和玻(bo)璃增(zeng)強纖維(wei)之(zhi)(zhi)(zhi)間界面(mian)移(yi)動。隨著時(shi)代發(fa)展(zhan)和技(ji)術的(de)(de)(de)(de)(de)革(ge)新，PCB板上(shang)出現CAF的(de)(de)(de)(de)(de)現象卻越(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)嚴重，究(jiu)其原因，是(shi)(shi)(shi)因為現在(zai)電(dian)(dian)子設(she)備(bei)上(shang)的(de)(de)(de)(de)(de)PCB板上(shang)需要(yao)焊接的(de)(de)(de)(de)(de)電(dian)(dian)子元件越(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)多，這樣也就(jiu)造成(cheng)了PCB板上(shang)的(de)(de)(de)(de)(de)金(jin)屬電(dian)(dian)極(ji)之(zhi)(zhi)(zhi)間的(de)(de)(de)(de)(de)距離(li)越(yue)(yue)(yue)來(lai)越(yue)(yue)(yue)短(duan)，這樣就(jiu)更加容易在(zai)兩個(ge)金(jin)屬電(dian)(dian)極(ji)之(zhi)(zhi)(zhi)間產生CAF現象。防止(zhi)發(fa)生離(li)子遷(qian)(qian)(qian)移(yi)故障的(de)(de)(de)(de)(de)一個(ge)重要(yao)措施當然(ran)是(shi)(shi)(shi)要(yao)保持(chi)使用(yong)環境的(de)(de)(de)(de)(de)干燥。廣東離(li)子遷(qian)(qian)(qian)移(yi)絕緣(yuan)電(dian)(dian)阻測(ce)試(shi)批量(liang)定制
