Soldering conditions:
ITEM	RECOMMENDED CONDITIONS
Hand soldering	Please practice according to below conditions: 1) Soldering temperature: 350°C Max. 2) Continuous soldering time: 3 s Max.
Conditions for Auto-dip	Caution: The condition mentioned above is a temperature on the PWB surface on which parts are mounted. There are cases where PWB temperature greatly differs from switch’s surface temperature depending on PWB material , size , thickness , etc . Care , therefore , should be used not to allow switch’s surface temperature to exceed 280°C.
Note: 1,After switches were soldered, please be careful not to clean switches with solvent. 2,Right after switches were soldered;please be careful not to load to on the knobs of switches. Please be careful not to pile up PCB. after switches were soldered. 3,Preservation under high temperature and high high humidity or corrosive gas should beavoided Especially . When you need to preserve for a long period ,do not open the carton.
