Time between soldering and removing from MBB must not
exceed the time indicated in J-STD-020:
Moisture sensitivity: level 3
Floor life: 168 h
Conditions: Tamb < 30 °C, RH < 60 %
In case of moisture absorption devices should be baked
before soldering. Conditions see J-STD-033D or label.
Devices taped on reel dry using recommended conditions
192 h at 40 °C (+ 5 °C), RH < 5 %.
