In the embossed tape-and-reel configuration, electronic components are placed in pockets embossed in the carrier tape. The cover tape is sealed to the carrier tape to encase the components in the pockets.
The following figure shows the typical tape components.
Cover tape
The cover tape is sealed by hot sealing. The pull strength limit for the cover tape is 20 to 120 grams when it is pulled at an angle of 175° to 180° with a peel-off speed of 300 ± 10 mm/min.
Carrier tape
The minimum leader part, or the length from the tape edge of the feeding side to the first component in the carrier tape, is 400 mm. The carrier tape material is conductive polystyrene.
The following dimensions are used in Carrier tape dimensions and Carrier tape dimensions.
- P = Pitch between cavity centers
- W = Width of carrier tape
- A = Dimension of cavity adjusted for component width
- B = Dimension of cavity adjusted for component length
- d = Distance between sprocket holes, 4 mm
The following figure illustrates the basic dimensions of the carrier tape. The center of the cavity is located in the middle between the sprocket holes.
The following table contains the product and package specific dimensions.
