前言 手機可靠性測試nNOKIA 檢測中心 Charles Cai Charles.rc.cai@ Ext: 61585n測試目的： 在產品設計階段發現產品之潛在缺陷或 設計缺失，避免於預期壽命內，在正常 操作狀況下發生功能失效的情形 環境測試： 在實驗室中模擬產品在其生命週期中可 能遭遇到的各種環境條件。

環境條件與環境參數 (IEC 721)環境條件之分類n環境條件與環境參數(續)單一環境參數分類（六大類）n自然環境(Natural environments)自然環境主要是由於氣象、地形等因數所引起 的。

氣候環境溫度（高、低溫）; 溫度變化（溫度循環、衝擊）;濕度 （穩態、循環濕度）; 大氣壓力（高、低壓及真空）; 降 落物 (雨淋、雪、冰雹); 輻射; 等項目。

n機械環境機械衝擊（即非穩態振動），如自由落體、跌落、外物碰 撞；穩態振動（包括週期性的正弦振動及非週期性的隨機 振動）、音響（噪音）。

n誘發環境(Induced environments) 誘發環境則為系統與裝備在搬運、組裝及操作 時所引起的。

環境條件與環境參數(續)n環境效應分析環境效應分析在某種特定的應用場合下，環境對於產品 的影響有下列三種情形：1.周圍媒介的條件，通常為空氣或水。

2.與產品連接結構的條件，亦即產品載具。

3.來自外部根源或活動的影響。

電磁環境 電磁環境又可分為電場（包括靜態場和交流場）、靜電放電、閃 電雷擊；磁場（包括靜態場和交流場）、導線傳送干擾等。

生物環境 生物環境又可分為：具有生物作用的物質[包含植物（包含霉與 菌）]及動物。

具機械作用環境 包括砂、塵、及泥等具有機械作用的顆粒。

具化學作用環境 包含海水鹽霧、二氧化硫、硫氫化物、臭氧、有機碳化合物等具 化學作用的物質。
