shelf life or humidity. The material does not break when bent and does not have any powder

or flake residue that rubs off.

2.2

Cover tape

The carrier tape is sealed with a transparent antistatic (surface resistivity ranging from

tape tensile strength is higher than 10 N.

The peeling force of the cover tape ranging from 0.1 N to 0.7 N in accordance with the

testing method EIA-481-C 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 °, and the test is performed at a speed of 120 ± 10 % mm/min.

2.3

Reels

The sealed carrier tape containing the WLCSP is reeled on 7 inch reels (see Figure 6 and

Table 3

for reel mechanical dimensions). These reels are compliant with EIA-481-C

standard. In particular, they are made of an antistatic polystyrene material. The reel color

may vary depending on supplier.

Dice quantity per reel is 3000 (with typical package thickness equal to 650 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. A reel may contain devices coming from 2

different wafer lots.

The reels have a minimum leader of 600 mm and a minimum trailer of 160 mm (in

compliance with EIA-481-C 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). It is affixed to the last turn of the carrier tape by using adhesive tape. The

trailer is located at the end of the reel and consists of empty sealed cavities.
