Abstract
Abstract There is provided a handling system for IC devices having a guide stage comprising a bank portion in which both sides of a IC device to be tested are held at a position other than a portion where terminals of the IC device project and a vacuum suction pore which suctorially sticks to the underside of the IC device at the midpoint of the bank portion. There is also provided a handling system for IC devices wherein multiple bank portions are provided on the stage, one half of which is used for carrying IC devices and the remaining half of which is used for discharging IC devices.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
156 words
A system for handling IC packages, comprising: a substantially flat and horizontally disposed stage platform having means for holding at least one IC package on said state platform; means for reciprocatingly moving said stage platform vertically between an upper position and a lower position; means for loading IC packages onto said stage platform into said IC holding means when said stage platform is at said lower position; testing means for testing at least one IC package on said stage platform when the stage platform is in the upper position; drive means for rotating said stage platform about its center; means for unloading at least one IC package off said stage platform after the stage platform is rotated and after the IC package has been tested; and control means for sequentially controlling the means for loading and the means for unloading the IC package, and the means for reciprocatingly moving and means for rotating the stage platform.
Claim 2
Independent Claim
156 words
A system for handling IC packages, comprising: a substantially flat and horizontally disposed stage platform having means for holding at least one IC package on said state platform; means for reciprocatingly moving said stage platform vertically between an upper position and a lower position; means for loading IC packages onto said stage platform into said IC holding means when said stage platform is at said lower position; testing means for testing at least one IC package on said stage platform when the stage platform is in the upper position; drive means for rotating said stage platform about its center; means for unloading at least one IC package off said stage platform after the stage platform is rotated and after the IC package has been tested; and control means for sequentially controlling the means for loading and the means for unloading the IC package, and the means for reciprocatingly moving and means for rotating the stage platform.
Claim 3
Dependent Claim
80 words
The IC handling system according to claim 1 wherein the stage platform has means for holding at least two IC packages thereon at symmetrically opposite positions relative to the stage platform center, and wherein the control means controls the loading means to load an IC package to be tested at one of said IC holding positions substantially concurrently with controlling the unloading means to unload an IC package after it is tested at the other of said IC holding positions.
Claim 4
Dependent Claim
93 words
The IC handling system of claim 1 wherein the stage platform has a vacuum suction hole at the center of the bottom of the means for holding at least one IC package, and wherein means for creating a vacuum at said suction hole are provided, and wherein the control means controls the vacuum creating means to create a vacuum after an IC is loaded at the IC holding position to thereby hold the IC in place, and for extinguishing said vacuum after stage platform rotation and before the means for unloading is actuated.
Claim 5
Dependent Claim
34 words
The IC handling system of claim 1 further including a heater and a temperature detector and controller for heating said stage platform and for keeping the stage platform at a predetermined IC testing temperature.
Claim 6
Dependent Claim
21 words
The IC handling system according to claim 1 wherein the stage platform has means for holding a plurality of IC devices.
Claim 7
Dependent Claim
31 words
The IC handling system according to claim 5 wherein the IC holding means are arranged in a circular fashion generally equidistantly from each other around the center of the stage platform.
Claim 8
Dependent Claim
30 words
The IC handling system according to claim 5 wherein the IC holding means comprise IC holding receptacles arranged in two generally parallel rows on opposite sides of the stage platform.
Claim 9
Dependent Claim
68 words
The IC handling system according to claim 7 wherein the means for loading the IC packages onto the stage platform comprises means for simultaneously loading IC packages to be tested into IC receptacles in one of said parallel rows, and wherein means for unloading the IC packages off said stage platform comprises means for simultaneously unloading tested IC packages from receptacles in the other of said parallel rows.
Claim 10
Dependent Claim
23 words
The IC handling device according to claim 1 wherein the IC testing means comprises means for testing a plurality of IC packages simultaneously.
Claim 11
Dependent Claim
83 words
The IC handling system according to claim 1 wherein the means for holding at least one IC package comprises a recess having a depth approximately equal to the distance that terminals of the IC package are displaced from one side thereof, so that the IC package can be placed in said recess with the said one side facing downward and so that the IC terminals can extend onto the stage platform outside of the recess for an IC package having substantially straight terminals.
Claim 12
Dependent Claim
80 words
The IC handling system according to claim 1 wherein the means for holding at least one IC package comprises a recess formed in said stage platform by a peripheral wall having a height approximately equal to the distance that terminals of the IC package are displaced from one side thereof, so that the IC package can be placed in said recess with the said one side facing downward and so that the IC terminals can be supported by said wall.
Claim 13
Dependent Claim
58 words
The IC handling system according to claim 11 wherein the IC packages to be handled have terminals which are bent so that their ends are substantially coplanar with the said one side of said IC package and wherein said walls are relatively narrow so that the terminal ends rest on the stage platform surface outside of said walls.
Claim 14
Dependent Claim
34 words
The IC handling system according to claim 1 wherein the means for loading and unloading IC packages on and off said stage platform comprise arm members having suction means for lifting said IC packages.
