## Abstract

A reusable transport and test tape which includes a plurality of insulated conductors adapted to receive and connect to the leads of the lead pack and to position the lead pack for reception of an integrated circuit for bonding of lead pack leads to the contact pads of the integrated circuit and to move the lead pack and integrated circuit into succeeding processing stations where the circuit is tested and packaged.

## Claims

### Claim 1

A reusable lead pack transport tape comprising:
an elongated metal tape;
a layer of insulating material bonded to one face of said tape;
windows in said metal tape and insulating layer spaced along said tape for receiving a lead pack of the type having outwardly extending leads;
a plurality of thin test pads bonded to and carried by said insulating layer spaced outwardly away from said windows and spaced in relation to one another; and
a plurality of thin spaced leads bonded to and carried on said insulating layer, spaced in relation to one another and splayed outwardly away from the edge of said windows to the test pads, the window to receive the lead pack with the outwardly extending lead pack leads with the lead pack leads connected to the window end of said thin spaced leads.

### Claim 2 (depends on 1)

A reusable lead pack transport tape as in claim 1, in which the elongated metal tape is provided with spaced sprocket holes along its edge to index the tape.
