## Abstract

The present invention is a reusable fixture for holding a TCP carrier tape that is of simple structure, allows the carrier tape to be held securely, and eliminates powder produced by friction during mounting of the carrier tape. The structure includes a reusable fixture with a bottom element for receiving the carrier tape, a frame that surrounds and protects an outer periphery of the bottom element, and a pair of resilient tape holding members for holding the carrier tape that can be deformed by a pair of engaging members that move in opposing directions along the same line so as to allow mounting of the carrier tape, the tape holding members being attached on at least one pair of opposing inner side faces of the frame at positions to allow the tape holding members to extend above the upper surface of the mounted carrier tape.

## Claims

### Claim 1

A resuable fixture for a carrier tape, comprising a bottom element for receiving one of a carrier tape to which a semiconductor chip is bonded and a carrier tape to which a semiconductor chip is be bonded, a frame extending around an outer periphery of said bottom element in order to protect the carrier tape, said frame having inner side faces, and at least a pair of resilient tape holding members for holding the carrier tape on said bottom element, each tape holding member having two ends, said tape holding members being temporarily deformed by at least a pair of engaging members that are engageable with said tape holding members and movable in an opposing relationship along a common straight line so as to allow the carrier tape to be mounted on the bottom element, the two ends of each tape holding member being joined and fixed at the inner side faces of said frame at a position so as to allow at least a portion of each tape holding member to overlie an edge of the carrier tape mounted on said bottom element.

### Claim 2 (depends on 1)

A reusable fixture for a carrier tape as set forth in claim 1, wherein each of said tape holding members has a recessed portion formed thereon.

### Claim 3 (depends on 2)

A reusable fixture for a carrier tape as set forth in claim 2, wherein said recessed portion is formed at a central portion of each of said tape holding members.

### Claim 4 (depends on 2)

A reusable fixture for a carrier tape as set forth in claim 2, wherein said recessed portion of each tape holding member is spaced from the edges of the carrier tape, each tape holding member having two portions positioned on opposite sides of the recessed portion which overlie the edge of the tape carrier.
