焊接和清洗過程 SOLDERING AND CLEANING PROCESSES

在所有操作過程中，請(qǐng)確保開關(guān)“off”位置

Keepall switch contacts in their "OFF" position forall operations

波峰焊:推薦焊錫溫度在260攝氏度，最多5秒鐘

Wave slodering: Rencommended Solder Temperature at 260℃ max. 5 seconds for IC type

手工焊:使用30瓦洛鐵控制溫度在320攝氏度，焊接時(shí)間大約2秒鐘

Hand Soidering:Use a soldering iron of 30 watts,controlled at320° approx.2 sec.while applying solder.

回流焊:(貼片型)回流爐最高溫度為260℃;溫度為240℃時(shí),最長時(shí)間不超過20秒。(如圖)

Reflow Soldering: Reflow zone 240℃ for 20 seconds. (attached drawing for reference)
