注意事項(xiàng)important notes:
2)手工焊接soldering iron
電烙鐵溫度為260℃時(shí),焊接時(shí)間不超過5秒。
焊接溫度越高,焊接時(shí)間應(yīng)越短(溫度每升高+10℃,時(shí)間應(yīng)減少1秒)。元件表面溫度應(yīng)在230℃以內(nèi)。
basic spec is£5sec when 260℃.
if temperature is higher, time should be shorter
(+10℃à-1sec ).surface temperature of the device should be under 230℃
