焊接和清洗過程 SOLDERING AND CLEANING PROCESSES
在所有操作過程中，請確保開關(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,最長時間不超過20秒。(如圖)
Reflow Soldering: Reflow zone 240℃ for 20 seconds. (attached drawing for reference)
清洗過程:清洗使用超音波方式，能給予更好效果;使用蒸汽清洗時，
溫度不可超多51攝氏度。
CleaningProcess:Fluxclean using force rinse,high agitation or triple bath cleaning method.Freon TF orTE give excellent
results. When vapormethods are used do not subject the switch to solvents at temperature above 51℃.
