As a detailed example, the diagram shown in Figure 15.2 outlines the dimensions of the tape used for 6 x 6mm x
1mm VFBGA devices:
Notes:
1. 10 sprocket hole pitch cumulative tolerance ± 02.
2. Camber not to exceed 1mm in 100mm.
3. Material: PS + C.
4. Ao and Bo measured as indicated.
5. Ko measured from a plane on the inside bottom of
the pocket to the top surface of the carrier.
6. Pocket position relative to sprocket hole measured as
true position of pocket, not pocket hole.
The cover tape has a total peel strength of 0.1N to 1.3N. The direction of the pull should be opposite the direction
of the carrier tape such that the cover tape makes an angle of between 165° and 180° with the top of the carrier
tape. The carrier and/or cover tape should be pulled with a velocity of 300±10mm during peeling.
Maximum component rotation inside the cavity is 10° in accordance with EIA-481-2. The cavity pitch tolerance
(dimension P1) is ±0.1mm.
The reel is made of high impact injection moulded polystyrene. The carrier tape is made of polystyrene with
carbon. The cover tape is made of antistatic polyester film and an antistatic heat activated adhesive coating.
