Lead terminals are immersed in rosin for 5 seconds and then immersed in solder
bath of +270 ± 5℃for 2 ± 0.5 second.
端子浸松香液中 5 秒後置於錫膏內,錫膏溫度:+270±5℃. 焊接時間: 2±0.5 秒.
1)IR reflow 遠紅外線熱風迴焊爐
Pre-heating conditions shall be+150 to +200℃ for 60 to 180 seconds. Ascending
time up to +245℃ shall be longer than 55 seconds.
Heating conditions shall be within 20~40 seconds at +245℃ min. But peak
temperature shall be lower than +255℃,then being place in natural condition for 1
hour, sounder shall be measured
預熱條件為加熱到+150 to +200℃為 60 到 180 秒. 加熱到 245℃時間須長於 55 秒.
焊接條件為 20~40 秒最低+245℃, 最高不可超過+255℃. 結束後須靜置於室溫中 1
小時後進行檢測
2)Soldering Iron 烙鐵
Soldering iron of +270±5℃ shall be placed 0.5mm above from electrode of
sounder. Melting solder through soldering iron shall be applied to electrode for 3±1
seconds, then being place in natural condition for 4 hours, sounder shall be
measured.
+270±5℃的烙鐵置於電極上方0.5mm 處, 以烙鐵將焊錫熔於電極上 3±1 秒,然後置
於室溫中 4 小時後進行檢測.
The force 10 seconds of 9.8N(1kg) is applied to each terminal is axial direction.
對每一端子以軸方向, 施 9.8N(1kg)拉力 10 秒.
The part shall be subjected to a vibration cycle of 10Hz to 55Hz in a period of 1
minute. Total peak amplitude shall be 1.55mm . The vibration test shall consist of 2
hours per axis in each three axes (X, Y , Z), Total 6 hours.
振幅 1.55mm, 頻率 10Hz-55Hz,時間 1 分鐘. X,Y ,Z 3 個方向各 2 小時, 共 6 小時.
