ESD產(chan)生(sheng)的問題

ESD（靜電(dian)(dian)放電(dian)(dian)）對電(dian)(dian)子(zi)(zi)產(chan)(chan)品(pin)(pin)造成的(de)(de)破壞(huai)和(he)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)有突(tu)發性(xing)(xing)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)和(he)潛(qian)在(zai)性(xing)(xing)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)兩(liang)種(zhong)。所謂(wei)突(tu)發性(xing)(xing)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)，指(zhi)的(de)(de)是(shi)(shi)器件(jian)(jian)被嚴重(zhong)損(sun)(sun)壞(huai)，功能喪(sang)失。這(zhe)(zhe)種(zhong)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)通常能夠在(zai)生產(chan)(chan)過(guo)程中(zhong)的(de)(de)質(zhi)(zhi)(zhi)量(liang)檢(jian)測中(zhong)能夠發現，因此給工廠帶來的(de)(de)主要是(shi)(shi)返工維修的(de)(de)成本(ben)。而(er)(er)潛(qian)在(zai)性(xing)(xing)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)指(zhi)的(de)(de)是(shi)(shi)器件(jian)(jian)部分被損(sun)(sun)，功能尚(shang)未喪(sang)失，且在(zai)生產(chan)(chan)過(guo)程的(de)(de)檢(jian)測中(zhong)不能發現，但在(zai)使(shi)用當中(zhong)會使(shi)產(chan)(chan)品(pin)(pin)變得不穩(wen)定，時好時壞(huai)，因而(er)(er)對產(chan)(chan)品(pin)(pin)質(zhi)(zhi)(zhi)量(liang)構成更大(da)的(de)(de)危害。這(zhe)(zhe)兩(liang)種(zhong)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)中(zhong)，潛(qian)在(zai)性(xing)(xing)失效占(zhan)據了90%，突(tu)發性(xing)(xing)失效只占(zhan)10%。也(ye)就(jiu)是(shi)(shi)說90%的(de)(de)靜電(dian)(dian)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)是(shi)(shi)沒辦法檢(jian)測到，只有到了用戶手(shou)(shou)(shou)里使(shi)用時才會發現。手(shou)(shou)(shou)機出現的(de)(de)經常死機、自動關機、話音質(zhi)(zhi)(zhi)量(liang)差(cha)、雜音大(da)、信號時好時差(cha)、按(an)鍵出錯等問題有絕大(da)多數與靜電(dian)(dian)損(sun)(sun)傷(shang)(shang)(shang)(shang)(shang)(shang)(shang)相關。也(ye)因為(wei)這(zhe)(zhe)一(yi)點，靜電(dian)(dian)放電(dian)(dian)被認為(wei)是(shi)(shi)電(dian)(dian)子(zi)(zi)產(chan)(chan)品(pin)(pin)質(zhi)(zhi)(zhi)量(liang)最(zui)大(da)的(de)(de)潛(qian)在(zai)殺手(shou)(shou)(shou)，靜電(dian)(dian)防(fang)(fang)護(hu)也(ye)成為(wei)電(dian)(dian)子(zi)(zi)產(chan)(chan)品(pin)(pin)質(zhi)(zhi)(zhi)量(liang)控(kong)制(zhi)的(de)(de)一(yi)項重(zhong)要內(nei)容。而(er)(er)國內(nei)外品(pin)(pin)牌手(shou)(shou)(shou)機使(shi)用時穩(wen)定性(xing)(xing)的(de)(de)差(cha)異也(ye)基(ji)本(ben)上反映了他們在(zai)靜電(dian)(dian)防(fang)(fang)護(hu)及產(chan)(chan)品(pin)(pin)的(de)(de)防(fang)(fang)靜電(dian)(dian)設(she)計上的(de)(de)差(cha)異。
