*Storage and Soldering
SMT(Surface Mount Type) ICs are sensitive for thermal stress with package absorbing
a) The unopened MP bag kept at 5 to 40’C / 20 to 80%RH could prevent moisture within two

moisture. So you should keep them not to absorb ambient moisture before soldering.
MP(Moisture Proof) bags prevent ICs from absorbing moisture during transportation
and storage at warehouses or factories.
b) After opening MP bags, you should store ICs at 30’C / 70%RH or under and solder them
c) When you must open MP bags temporarily, opening time should be within ten minutes.
d) Over the time period above, you are recommended to bake ICs at 125’C in 20 to 24 hours
within four days.
years.
And then, you should fold the opening side of bags into two and close them with adhesive
tape.
before using. (Four times maximum, less than 96 hours totally)
As for Infrared Reflow and Air Reflow, see Fig-1, and as for VPS Reflow, see Fig-2.
Those temperature profiles show the temperature on the IC surface.
You can apply a maximum of four times.
