and one to the reel box. Each label carries the
following information:
– PRODUCT: sales type
– LOT NUMBER: reel number
– POS:
total number of positions
– GOOD:
number of good positions
– FAIL:
number of fail positions
– DATE:
date of sealing
In addition, the antistatic bag and the delivery box
carry a self adhesive plastic “ESD” warning label,
85 x 38 mm in size, indicating “Electrostatic
sensitive devices”.
Each reel is packed in a reel box, made of recycled
cardboard. The size of the reel box depends on its
origin. Several reel boxes are packed in a delivery
box, which is also made of recycled cardboard.
A delivery note is provided, listing the following
information:
– Date of sealing
– Reel numbers
– Total number of positions, with the details of
positions per reel
– Order number and customer name
– Sales type
– Tape type
RECOMMENDED ACCEPTANCE CRITERIA
The product identity should be checked against
the delivery documentation, and the quantity of
good positions on the reel recorded. The product
may be tested in accordance with the appropriate
data sheet, the conditions depending on the
product type, and the ISSUER or USER mode (for
ST13xx products).
For delivery acceptance, ST recommends
sampling the Micromodules from the beginning of
the reel. The sampling AQL should be applied, to
the ISO 2859 standard (test level II, normal test).

Any observed discrepancies should be reported in
writing to the ST quality department. Table 6
shows the recommended AQL levels.
The visual and mechanical test specification and
test conditions are described in Table 7.
Defect Acceptance Rate
Each reel contains the stated number of defective
devices, distributed so that no more than 20% of
them are found in a contiguous block on the tape.
ST’s own quality acceptance standard guarantees
that the customer will be informed when the
electrical yield is less than 90%.
The part numbers and re-ordering information will
be set according to ST’s current product coding
policy, as shown on the individual product data
sheets, or as agreed with the customer.
Reels that do not pass inspection should be
returned to ST within 15 working days after
delivery.
