Time(s)
●
IR Reflow soldering :
Preheat at 3℃ per second to 217℃ and using lead free solder ,
IR at 245℃ for 30seconds Max.
●
Rework flow:
Component must withstand two IR reflow cycles with a cool down
between cycles
●
Temperature is measured at the terminal portion of product
(Using thermocoupler for measurement).
●
This profile is reference data we recommend. Please check in your
actual process.

Soldering
Natural
cooling
●
For reliable soldering, the thickness of solder paste screen should
be over the terminal co-planality.
●
The cutted end of terminal has no plating
(out of subject of solder ability).
