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 the EIA-481-C 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 5000 (with typical package thickness equal to 650 µm). In

compliance with 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-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). 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).
