QFP packages can be supplied in tape and reel shipping media. The reels have a 13” typical diameter. cavity tape. The cover tape is transparent anti static or conductive. same side as the sprocket holes in the tape. the corresponding shipping media. Table 1. QFP packages available in tape and reel packing

1 Reel description

Figure 1. Reel diagram

Table 2. Reel dimensions(1)

  1. NA stands for “not applicable”.
  2. W1 is measured at the hub.

2 Leader and trailer tape specifications

width not higher than the one of the cover tape. and the remaining components in the cavities. Figure 2. Leader and trailer tape schematics

3 Labeling

  • On the box that directly holds the reel
  • On the damp proof bag if the units are dry packed
  • On the reel itself The label is attached to the flange that is facing the user when the tape is extracted from the reel at the top right (see Figure 3).

4 Device Orientation

The largest axis of the component outline is perpendicular to the tape length. on tape. Pin 1 is located on the top right corner of the package. Figure 4. Device orientation on tape

5 Carrier tape mechanical dimensions

5.1 Carrier tape width ≤ 24 mm

Figure 5. Embossed carrier tape (width ≤ 24 mm) Table 3. Carrier tape constant dimensions (width ≤ 24 mm)

  1. The maximum radius the tape with or without components can bend without damage is specified in Section 6: Bending

5.2 Carrier tape width > 24 mm

Figure 6. Embossed carrier tape (width > 24 mm) Table 4. Carrier tape variable dimensions (width ≤ 24 mm)

  1. The cavity defined by A0, B0 and K0 surrounds the component with sufficient clearance so that:
  • The component does not protrude above the top surface of the carrier tape.
  • Rotation of the component is limited to 20° maximum for 12 mm tapes and to 10° maximum for 16 mm and 24mm tapes.
  • Lateral movements of the component are restricted to 1.0 mm maximum for 16 mm and 24 mm tapes.

Table 5. Carrier tape constant dimensions (width > 24 mm)

  1. The maximum radius the tape with or without components can bend without damage is specified in Section 6: Bending

Table 6. Carrier tape variable dimensions (width > 24 mm)

  1. The cavity defined by A0, B0 and K0 surrounds the component with sufficient clearance so that:
  • The component does not protrude above the top surface of the carrier tape.
  • Rotation of the component is limited to 10° maximum for 44 mm tapes.
  • Lateral movements of the component are restricted to 1.0 mm maximum.

6 Bending radius requirements

7 Camber requirements

Carrier camber should not exceed more than 1 mm in 250 mm of carrier tape length. Figure 8. Camber requirements
