PCB電路(lu)板高溫老(lao)化(hua)(hua)房(fang);PCB高溫老(lao)化(hua)(hua)房(fang);pcb線路(lu)板高溫老(lao)化(hua)(hua)壽命測試;PCB電路(lu)板老(lao)化(hua)(hua)室

PCB電路(lu)板(ban)高(gao)(gao)溫(wen)老化(hua)房即用于pcb板(ban),PCB電路(lu)板(ban),pcb印(yin)刷(shua)板(ban),PCB線路(lu)板(ban)等材料的(de)高(gao)(gao)溫(wen)及恒溫(wen)老化(hua)壽(shou)(shou)命試(shi)驗。pcb電路(lu)板(ban)受到外界因素的(de)破(po)(po)壞而減少其壽(shou)(shou)命，高(gao)(gao)溫(wen)是(shi)對PCB電路(lu)板(ban)zui普遍、破(po)(po)壞性的(de)主要因素。高(gao)(gao)溫(wen)環境會大幅(fu)降(jiang)低PCB導體間(jian)的(de)絕緣抵抗性、加(jia)速高(gao)(gao)速分解、降(jiang)低Q值(zhi)、及腐蝕導體。為提升產(chan)品質量，是(shi)pcb電路(lu)板(ban)廠家必要的(de)測試(shi)過程。

PCB就是(shi)印刷電路(lu)(lu)板（Printed circuit board，PCB）幾乎會出現(xian)在每一種(zhong)電子設備(bei)當中。如果在某(mou)樣設備(bei)中有(you)電子零(ling)件，那么它們也(ye)都是(shi)鑲在大小各異的(de)PCB上。隨(sui)(sui)著(zhu)電子設備(bei)越(yue)(yue)來(lai)越(yue)(yue)復雜，需要的(de)零(ling)件越(yue)(yue)來(lai)越(yue)(yue)多，PCB上頭(tou)的(de)線路(lu)(lu)與零(ling)件也(ye)越(yue)(yue)來(lai)越(yue)(yue)密集了(le)，自然對PCB電路(lu)(lu)板的(de)質量(liang)要求也(ye)愈加嚴格，不管什么東西隨(sui)(sui)著(zhu)時間的(de)推移，都會老(lao)化，PCB電路(lu)(lu)板也(ye)如此。pcb電路(lu)(lu)板便需要通過系列高溫老(lao)化房來(lai)進行PCB電路(lu)(lu)板老(lao)化壽命測試(shi)。
