D10, D15, D20, D22, C20, C30 MICROMODULES Memory Micromodules General Information for D1, D2 and C Packaging ■ Micromodules were developed specifically for embedding in Smartcards and Memory Cards ■ The Micromodule provides: potting side contact side – Support for the chip – Electrical contacts D15 – Suitable embedding interface for gluing the module to the plastic package 1 1 D10 D20 1 1 DESCRIPTION Memory Cards consist of two main parts: the plastic card, and the embedded Micromodule (which, in turn, carries the silicon chip). The plastic card is made of PVC, ABS or similar material, and can be over-printed with graphics, text, and magnetic strips. The Micromodule is embedded in a cavity in the plastic card. The Micromodules are mounted on Super 35 mm metallized epoxy tape, and are delivered on reels. These contain all of the chips from a number of wafers, including those chips that were found to be non-functioning during testing. Traceability is ensured by a label fixed on the reel. 1 Micromodules delivered as a continuous Super 35 mm tape. (This differs from the standard 35 mm tape in the spacing distance between the indexing holes.) 1 ■ 1 Physical dimensions and contact positions compliant to the ISO 7816 standard 1 ■ D22 C30 C20 Table 1.

Dice sawing 2. Dice attach 3. Wire bonding 4. Potting 5. Milling (depending on product) The range of products and types of Micromodule are summarized in Table 1 and Table 2. For large volumes, ST is able to offer customized module tape. DELIVERY The Super 35mm metallized epoxy tape is delivered on reels, as shown in Figure 1. These contain all of the chips from a number of wafers, including those chips that were found to be nonfunctioning during testing. Traceability is ensured by a label fixed on the reel. The typical quantity is 10,000 modules per reel, with priority given to lot integrity on the reel. The maximum quantity is 15,000 per reel. Parts which are faulty (mechanically or electrically defective) are identified by punch holes. The specification for the reject punch holes is shown in Figure 4 for the D10 micromodule, in Figure 5 for the D15 micromodule, in Figure 6 for the D20 micromodule, and in Figure 7 for the D22 micromodule. Tape joins (tape splicing) are never more than 10 per 10 metre length, as shown in Figure 2 and Figure 3. At least 2.1 m of leader, and 2.1 m of trailer is included on each reel. Each is made of PVC Super 35 mm tape, without metalisation, and is opaque to infrared and white light. A “failure” marking of reject holes is included at the beginning and end of the tape of a minimum of 5 consecutive module pitches (double positions). Modules should be stored within the temperature range -40 °C to + 85 °C, for no more than 1 year. Each reel is packed in an antistatic bag, along with a desiccant bag, and a humidity indicator card. This card indicates the level of humidity as follows: 30 - Blue: protection assured 40 - Pink: renew the desiccant bag 50 - Pink: protection no longer ensured Three self adhesive plastic identification labels are attached: one to the reel, one to the antistatic bag, 2/13 MICROMODULES Table 3.

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). Table 5. Size of the Reel Box Manufacturing Location Size of Reel Box Rousset 370 x 390 x 80 mm Casablanca 373 x 370 x 78 mm Table 6. AQL Levels Defect AQL Total defects - mechanical and electrical 0.65 Mechanical defects 0.65 Electrical defects 0.65 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. Table 7.
