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.

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).
