SOLDERING PROCESS
△HAND SOLDERING : Use a soldering iron of 30 watts, controlled at 350 approximately ℃ max 5 seconds while
applying solder.
△REFLOW SOLDERING: When applying reflow soldering, the peak temperature or the reflow oven should be set
at 260 max.℃
△WAVE SOLDERING: Recommended solder temperature at 500℉ (260℃) max. 5 seconds for through hole type.
subject to P.C.B 1.6mm thickness.
