AQL Levels Manufacturing Location Size of Reel Box Rousset 370 x 390 x 80 mm Casablanca 373 x 370 x 78 mm Defect AQL Total defects - mechanical and electrical 0.65 Mechanical defects 0.65 Electrical defects 0.65 Table 7. Visual and Mechanical Specification and Test Conditions Note: 1. Test 3 and 4 are conducted in accordance with MIL-STD-833. Test Description and Method Reject Criteria 1 Contact area Glue or particles, scratches print, sever defects on contact area damaging the gold layer. Visual test distance 30 cm, naked eye. 2 Chip covering Thickness and external dimension measurement exceeding total thickness, or other dimensions not complying to the drawings 31 Die bond strength Die shear force < 10 N 41 Wire bonding Wire lift or broken at pull test with < 4 g 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). |
