Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
An apparatus for manipulating integrated circuit dice comprising: means for holding an array of dice contact side down at a predetermined source position, said dice being adhesively attached to the bottom side of a support member; means for knocking a selected die from said array of dice down from said support member at a predetermined source position directly onto rotatable intermediate receptacle means, wherein said means for knocking a selected die includes striking means, positioned above said support member, for striking downward on and penetrating said support member to dislodge dice therebelow wherein said striking member includes a needle member having four needles positioned in a rectangular array and a fifth spring loaded needle positioned within said rectangular array and extending a predetermined distance below the others of said needles for perforating said support member and striking a die adhesively attached therebelow and means for driving said needle member downward; a rotating cylinder; a tube slidably mounted in a housing supported by said rotating cylinder; a cam cylinder within and coaxial with said rotating cylinder; a cam follower attached to said slidable tube, wherein relative rotation of said cam and said cylinder causes the sliding translation of said tube within said housing in a direction substantially perpendicular to the outer surface of said rotating cylinder; means for rotating said cylinder 180 degrees about a horizontal axis; and means for holding said selected die during rotation and for releasing said selected die after rotation.
Claim 2
Independent Claim
243 words
An apparatus for manipulating integrated circuit dice comprising: means for holding an array of dice contact side down at a predetermined source position, said dice being adhesively attached to the bottom side of a support member; means for knocking a selected die from said array of dice down from said support member at a predetermined source position directly onto rotatable intermediate receptacle means, wherein said means for knocking a selected die includes striking means, positioned above said support member, for striking downward on and penetrating said support member to dislodge dice therebelow wherein said striking member includes a needle member having four needles positioned in a rectangular array and a fifth spring loaded needle positioned within said rectangular array and extending a predetermined distance below the others of said needles for perforating said support member and striking a die adhesively attached therebelow and means for driving said needle member downward; a rotating cylinder; a tube slidably mounted in a housing supported by said rotating cylinder; a cam cylinder within and coaxial with said rotating cylinder; a cam follower attached to said slidable tube, wherein relative rotation of said cam and said cylinder causes the sliding translation of said tube within said housing in a direction substantially perpendicular to the outer surface of said rotating cylinder; means for rotating said cylinder 180 degrees about a horizontal axis; and means for holding said selected die during rotation and for releasing said selected die after rotation.
Claim 3
Independent Claim
160 words
An apparatus for manipulating integrated circuit dice comprising: a dice holder for holding an array of dice contact side down, wherein the dice are adhesively attached to the bottom side of a support member; a cylinder supported below said dice holder; a slidable arm connected to the outer surface of said cylinder, wherein said slidable arm is moveable in a direction perpendicular to the outer surface of said cylinder; a cam cylinder rotatably mounted within and coaxial with said cylinder; a cam follower connected to said slidable arm and to said cam, wherein relative rotation of said cylinder and said cam cylinder causes said slidable arm to move in a direction perpendicular to the outer surface of said cylinder; means for independently rotating said cylinder and said cam cylinder; means for releasing a die from said die holder to a position on said slidable arm; and means for holding such die onto said slidable arm during rotation of said cylinder.
Claim 4
Independent Claim
160 words
An apparatus for manipulating integrated circuit dice comprising: a dice holder for holding an array of dice contact side down, wherein the dice are adhesively attached to the bottom side of a support member; a cylinder supported below said dice holder; a slidable arm connected to the outer surface of said cylinder, wherein said slidable arm is moveable in a direction perpendicular to the outer surface of said cylinder; a cam cylinder rotatably mounted within and coaxial with said cylinder; a cam follower connected to said slidable arm and to said cam, wherein relative rotation of said cylinder and said cam cylinder causes said slidable arm to move in a direction perpendicular to the outer surface of said cylinder; means for independently rotating said cylinder and said cam cylinder; means for releasing a die from said die holder to a position on said slidable arm; and means for holding such die onto said slidable arm during rotation of said cylinder.
Claim 5
Dependent Claim
60 words
The apparatus of claim 2, further comprising: a die adjuster located adjacent to said cylinder, wherein movement of said slidable arm in a direction perpendicular to the outer surface of said cylinder brings a die located thereon into contact with said die adjuster, and wherein said die adjuster positions such die at a known spatial relationship with said slidable arm.
Claim 6
Dependent Claim
33 words
The apparatus of claim 2, wherein said die holding means comprises a low pressure region formed within said slidable arm, whereby dice are held in position on said slidable arm by atmospheric pressure.
Claim 7
Dependent Claim
55 words
The apparatus of claim 2, wherein said die releasing means comprises a striker positioned above said dice holder, wherein said striker contains a plurality of pins, and wherein movement of said striker against an upper surface of said dice holder causes the pins to press on a die and release it from the adhesive attachment.
