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, acc. 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 %.
TAPE AND REEL
PLCC-3 components are packed in antistatic blister tape
(DIN IEC (CO) 564) for automatic component insertion.
Cavities of blister tape are covered with adhesive tape.

MISSING DEVICES
A maximum of 0.5 % of the total number of components per
reel may be missing, exclusively missing components at the
beginning and at the end of the reel. A maximum of three
consecutive components may be missing, provided this gap
is followed by six consecutive components.

The tape leader is at least 160 mm and is followed by a
carrier tape leader with at least 40 empty compartments. The
tape leader may include the carrier tape as long as the cover
tape is not connected to the carrier tape. The least
component is followed by a carrier tape trailer with a least 75
empty compartments and sealed with cover tape.
