PCB電路(lu)(lu)(lu)板高(gao)溫(wen)老(lao)(lao)化(hua)(hua)房;PCB高(gao)溫(wen)老(lao)(lao)化(hua)(hua)房;pcb線路(lu)(lu)(lu)板高(gao)溫(wen)老(lao)(lao)化(hua)(hua)壽(shou)命測試;PCB電路(lu)(lu)(lu)板老(lao)(lao)化(hua)(hua)室

PCB電路(lu)(lu)板(ban)高(gao)溫老化房即(ji)用(yong)于(yu)pcb板(ban),PCB電路(lu)(lu)板(ban),pcb印刷板(ban),PCB線路(lu)(lu)板(ban)等(deng)材料的高(gao)溫及恒溫老化壽(shou)命試驗。pcb電路(lu)(lu)板(ban)受(shou)到(dao)外界(jie)因素(su)的破壞(huai)而減少其壽(shou)命，高(gao)溫是對PCB電路(lu)(lu)板(ban)zui普(pu)遍、破壞(huai)性的主要因素(su)。高(gao)溫環境(jing)會大幅降(jiang)低PCB導(dao)體(ti)間的絕(jue)緣抵抗性、加(jia)速高(gao)速分解、降(jiang)低Q值、及腐蝕導(dao)體(ti)。為提升產品質量，是pcb電路(lu)(lu)板(ban)廠家必要的測試過程。

PCB就是(shi)印(yin)刷(shua)電(dian)路(lu)(lu)板(ban)（Printed circuit board，PCB）幾乎會(hui)(hui)出(chu)現(xian)在(zai)每一種電(dian)子(zi)設備當(dang)中。如果在(zai)某樣設備中有(you)電(dian)子(zi)零件(jian)，那么(me)它們也(ye)(ye)都是(shi)鑲在(zai)大小各異的PCB上。隨著電(dian)子(zi)設備越來(lai)越復(fu)雜，需要(yao)的零件(jian)越來(lai)越多(duo)，PCB上頭的線路(lu)(lu)與(yu)零件(jian)也(ye)(ye)越來(lai)越密集了(le)，自然對PCB電(dian)路(lu)(lu)板(ban)的質量要(yao)求(qiu)也(ye)(ye)愈加嚴格，不管(guan)什么(me)東西隨著時間的推移，都會(hui)(hui)老化，PCB電(dian)路(lu)(lu)板(ban)也(ye)(ye)如此(ci)。pcb電(dian)路(lu)(lu)板(ban)便需要(yao)通過(guo)系列高溫老化房來(lai)進行PCB電(dian)路(lu)(lu)板(ban)老化壽命測試。
