According to J-STD-020
DRYPACK
Devices are packed in moisture barrier bags (MBB) to
prevent the products from moisture absorption during
transportation and storage. Each bag contains a desiccant.
FLOOR LIFE
Floor life (time between soldering and removing from MBB)
must not exceed the time indicated on MBB label:
Floor life: 4 weeks
Conditions: Tamb < 30 °C, RH < 60 %
Moisture sensitivity level 2a, according to J-STD-020.
DRYING
In case of moisture absorption devices should be baked
before soldering. Conditions see J-STD-020 or label.
Devices taped on reel dry using recommended conditions
192 h at 40 °C (+ 5 °C), RH < 5 %.
