TAPE AND REEL
PLCC-2 components are packed in antistatic blister tape
(DIN IEC (CO) 564) for automatic component insertion.
Cavities of blister tape are covered with adhesive tape.
component is followed by a carrier tape trailer with a least
75 empty compartments and sealed with cover 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

COVER TAPE REMOVAL FORCE
The removal force lies between 0.1 N and 1.0 N at a removal
speed of 5 mm/s. In order to prevent components from
popping out of the blisters, the cover tape must be pulled off
at an angle of 180° with regard to the feed direction.
