Abstract

Abstract A package is provided for connecting a plurality of molded carriers each having an integrated circuit which has been previously bonded to the electrical leads of a TAB tape. The package flexibly and sequentially connects a plurality of the carriers, so as to form a flexible and continuous chain of the carriers. The package preferably utilizes a flexible conductive tape which is continuously provided on parallel ends, or edges, of each carrier, so as to link the plurality of carriers together. The package permits continuous feeding of the carriers into subsequent test and assembly machines utilized to attach the integrated circuit to a printed circuit board.

A package for carriers of integrated circuits for handling the integrated circuit prior to attachment to a printed circuit board comprising: a plurality of integrated circuits, each of said integrated circuits having a plurality of electrical leads attached to and extending outwardly from said integrated circuit; a plurality of carriers, each of said carriers retaining an individual integrated circuit by rigidly retaining in a substantially planar direction all of said plurality of electrical leads attached to and extending outwardly from said integrated circuit; and means for flexibly and sequentially connecting said plurality of carriers to another of said carriers so as to form a flexible chain of said carriers and so that said carriers can be folded over one another, wherein said means for flexibility and sequentially connecting said plurality of carriers to each other comprises an electrically conductive material.
Claim 2
Dependent Claim 140 words
A package for carriers of integrated circuits for handling the integrated circuit prior to attachment to a printed circuit board comprising: a plurality of integrated circuits, each of said integrated circuits having a plurality of electrical leads attached to and extending outwardly from said integrated circuit; a plurality of carriers, each of said carriers retaining an individual integrated circuit by rigidly retaining in a substantially planar direction all of said plurality of electrical leads attached to and extending outwardly from said integrated circuit; and means for flexibly and sequentially connecting said plurality of carriers to another of said carriers so as to form a flexible chain of said carriers and so that said carriers can be folded over one another, wherein said means for flexibility and sequentially connecting said plurality of carriers to each other comprises an electrically conductive material.
Claim 3
Dependent Claim 29 words
A package for integrated circuits as recited in claim 1 wherein said means for flexibly and sequentially connecting said plurality of carriers to each other comprises an adhesive tape.
Claim 4
Independent Claim 126 words
A method for packaging carriers of integrated circuits for handling the integrated circuit prior to attachment to a printed circuit board comprising the following steps: providing a plurality of integrated circuits each having a plurality of electrical leads attached to and extending outwardly from said integrated circuit; retaining said plurality of electrical leads attached to and extending outwardly from each of said integrated circuits in a substantially planar manner by a carrier ring; and connecting each of said carrier rings to another by means of a flexible link, so that the carrier rings are flexibly and sequentially connected to form a chain and so that said carriers can be folded over one another, wherein said flexible link within said connecting step comprises an electrically conductive tape.
Claim 5
Independent Claim 126 words
A method for packaging carriers of integrated circuits for handling the integrated circuit prior to attachment to a printed circuit board comprising the following steps: providing a plurality of integrated circuits each having a plurality of electrical leads attached to and extending outwardly from said integrated circuit; retaining said plurality of electrical leads attached to and extending outwardly from each of said integrated circuits in a substantially planar manner by a carrier ring; and connecting each of said carrier rings to another by means of a flexible link, so that the carrier rings are flexibly and sequentially connected to form a chain and so that said carriers can be folded over one another, wherein said flexible link within said connecting step comprises an electrically conductive tape.
Claim 6
Dependent Claim 25 words
A method for packaging carriers of integrated circuits as recited in claim 3 wherein said flexible link within said connecting step comprises an adhesive tape.
Claim 7
Dependent Claim 284 words
A package for carriers of integrated circuits comprising: a plurality of integrated circuits, each of said integrated circuits having a plurality of electrical leads attached to and extending outwardly from said integrated circuits; at least two adjacently positioned carriers, each of said carriers retaining an individual integrated circuit by rigidly retaining in a substantially planar direction all of said plurality of electrical leads attached to and extending outwardly from said integrated circuit; each of said carriers having top and bottom surfaces and each of said surfaces having first and second opposed edges; and first, second, third and fourth strips of adhesive tape, said first adhesive tape having a portion adhering to a portion of the top surface near said first edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said second adhesive tape having a portion adhering to a portion of the bottom surface near said first edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said first and second adhesive tapes being secured together a distance along said portion extending between said carriers to form a flexible hinge, said third adhesive tape having a portion adhering to a portion of the top surface near said second edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said fourth adhesive tape having a portion adhering to a portion of the bottom surface near said second edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said third and fourth adhesive tapes being secured together a distance along said portion extending between said carriers to form a flexible hinge.
Claim 8
Dependent Claim 284 words
A package for carriers of integrated circuits comprising: a plurality of integrated circuits, each of said integrated circuits having a plurality of electrical leads attached to and extending outwardly from said integrated circuits; at least two adjacently positioned carriers, each of said carriers retaining an individual integrated circuit by rigidly retaining in a substantially planar direction all of said plurality of electrical leads attached to and extending outwardly from said integrated circuit; each of said carriers having top and bottom surfaces and each of said surfaces having first and second opposed edges; and first, second, third and fourth strips of adhesive tape, said first adhesive tape having a portion adhering to a portion of the top surface near said first edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said second adhesive tape having a portion adhering to a portion of the bottom surface near said first edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said first and second adhesive tapes being secured together a distance along said portion extending between said carriers to form a flexible hinge, said third adhesive tape having a portion adhering to a portion of the top surface near said second edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said fourth adhesive tape having a portion adhering to a portion of the bottom surface near said second edge of each of said adjacent carriers and having a portion extending between said adjacent carriers, said third and fourth adhesive tapes being secured together a distance along said portion extending between said carriers to form a flexible hinge.
Claim 9
Dependent Claim 30 words
A package as set forth in claim 5 wherein said adhesive tape extending between adjacent carriers is of sufficient length so that said carriers can be folded over one another.
Claim 10
Dependent Claim 15 words
