    1.迴焊爐測試 / Resistance to Soldering Heat

    260°C, 10sec, 2times

    2.吃錫性測試 / Solderability (Reflow Soldering)

    230°C, 3sec, (Lead Solder)

    3.冷熱衝擊試驗 / Thermal Shock Test

    0°C (15sec) ~ 100°C (15sec)

    4.溫度循環試驗 / Temperature Cycle

    - 40°C (30min) ~ 25°C (5min) ~ 100°C (30min) ~ 25°C (5min)

    5.高溫儲存 / High Temperature Storage

    100°C 1000hrs

    6.低溫儲存 / Low Temperature Storage

    - 40°C 1000hrs

    7.高溫高濕儲存 / Temperature Humidity Storage

    60°C, RH=90%1000hrs

    8.點亮測試 / Operating Life (Burn-In)

    a. 25°C,IF=20mA 1000hrs

    b. 60°C, RH=90%,IF=20mA 1000hrs

    其實還蠻多要看客戶需求!
