1 - The solder paste shall be printed in a thickness of 150 to 200µm.
2 - The SIR test of the solder paste shall be done（Based on JIS-Z-3284）
3 - IR reflow Pb Free Process suggestin profile (Based on J-STD-020-C):
Rapid heating, partial heating or rapid cooling will easily cause defect of the component. So preheating and gradual cooling process is
suggested. IR soldering has the highest yields due to controlled heating rates and solder liquidus times. Make sure that the element is not
subjected to a thermal gradient steeper than 3 degrees per second. 2 degrees per second is the ideal gradient. During the soldering process,
pre- heating to within 175 degrees of the solders peak temperature is essential to minimize thermal shock.

Soldering recommend paste is Sn 96.5/Ag 3.5
- Preheat
1.The temperature rising speed is suggested to be 2~3°
C/s.
2.Appropriate preheat time will be from 60 to 120 seconds.
3.Temp. maintain at 175 +/-25° 120 seconds.

- Heating
1.Careful about sudden rise in temperature as it may worsen
the solder ability.
2.Set the peak temperature in 235° 10-20s or 260° 3-10s.
