Packing specifications and labeling description

16

The cavities in the carrier tape have been designed to avoid any damage to the

components. Specific hole is present to improve device stability during sealing and pick up.

The embossed carrier tape is in a black conductive material (surface resistivity within 10E5

and 10E11 ohm/sq). Use of this material protects the component against damage from

electrostatic discharge and ensures the total discharge of the component prior to placement

on the PCB. Conductivity is guaranteed to be constant and not affected by shelf life or

humidity. The material will not break when bent and does not have any residue to rub off,

powder, or flake.

Cover tape

The carrier tape is sealed with a transparent, antistatic (surface resistivity within 10E5 and

10E11 ohm/sq) polyester film cover tape with a heat activated adhesive. The cover tape

tensile strength is higher than 10 N.

The peeling force of the cover tape is between 0.08 N and 0.5 N in accordance with the

testing method EIA-481-D and IEC 60286-3. Cover tape is peeled back in the direction

opposite to the carrier tape travel; the angle between the cover tape and the carrier tape is

between 165 and 180 degrees and the test is done at a speed of 120 ±10% mm/minute.

3.3

Reels

The sealed carrier tape with the Flip Chip is reeled on seven-inch reels (see Figure 5 for reel

mechanical dimensions). These reels are compliant with EIA-481-D standard. In particular,

they are made of an antistatic polystyrene material. Color of the reel may vary depending on

supplier.

Dice quantity per reel is 10000 (with typical package thickness equal to 380 µm). In

compliance with the IEC 60286-3, each reel contains a maximum of 0.1% empty cavities.

Two successive empty cavities are not allowed. Each reel may contain components coming

from 2 different wafer lots.

Each reel has a minimum leader of 400 mm and a minimum trailer of 160 mm (compliant

with EIA 481-D and IEC 60286-3 standards). The leader makes up a portion of carrier tape

with empty cavities and sealed by cover tape at the beginning of the reel (external side). The

leader is affixed to the last turn of the carrier tape by using adhesive tape. The trailer is at

the end of the reel and consists of empty, sealed cavities (see Figure 6).
