Abstract
A reel tape includes a base tape for reel winding, a chip mounting section on the base tape, on which a bare chip is to be mounted and an adhesive layer coated on the chip mounting section. The bare chip is provisionally bonded to the chip mounting section with the adhesive layer interposed therebetween such that the bare chip is detachable. Therefore, the bare chip can be detached from the tape for chip testing, for example, and mounted on the tape again after the testing. The reel tape further includes a protector, e.g. a bar, provided on the base tape and along the chip mounting section in a tape conveying direction. The protector prevents the bare chip from contacting an overlaying portion of the base tape when the base tape is wound on a reel.
Claims4
A reel tape, comprising:
- a base tape to be wound in a reel;
- a chip mounting section on the base tape, on which a bare chip is to be mounted;
- an adhesive layer coated on the chip mounting section, the adhesive layer permitting a bare chip to be selectively bonded to and detached from the chip mounting section;
- a protection bar provided on the base tape and along the chip mounting section in a direction substantially parallel to a tape conveying direction, the protection bar preventing the bare chip from contacting an overlaying portion of the base tape when the base tape is wound;
- and
- a tape bending area having a groove formed on the base tape at an end of the chip mounting section in a direction substantially perpendicular to the tape conveying direction.
A reel tape comprising:
- a base tape to be wound in a reel;
- a chip mounting section on the base tape, on which a bare chip is to be mounted;
- an adhesive layer coated on the chip mounting section, the adhesive layer permitting a bare chip to be selectively bonded to and detached from the chip mounting section;
- and
- a protection section provided along an edge of the base tape in a direction substantially parallel to a tape conveying direction, the protection section being formed such that the edge of the base tape is corrugated in the tape conveying direction, for preventing the chip mounting section from bending when the base tape is wound.
