Abstract

This apparatus permits bulk handling and orienting of various sizes and geometries of integrated circuit elements. The contact geometry of the integrated circuit elements cooperates with structure in a vibratory bowl to effect this result. An integrated circuit element includes, as in A and B, a plurality of contact terminals disposed about the periphery of the element. The contacts are nonsymmetrically disposed with respect to the periphery to establish a clear path along one dimension of the element, typically the length. The clear path can be located at positions other than that of positions shown but must be adapted to cooperate with a ridge member included in one or more tracks of a vibratory bowl.

Apparatus for Orienting Integrated Circuit Elements

This apparatus permits bulk handling and orienting of various sizes and geometries of integrated circuit elements. The contact geometry of the integrated circuit elements cooperates with structure in a vibratory bowl to effect this result. An integrated circuit element includes, as in A and B, a plurality of contact terminals disposed about the periphery of the element. The contacts are nonsymmetrically disposed with respect to the periphery to establish a clear path along one dimension of the element, typically the length. The clear path can be located at positions other than that of positions shown but must be adapted to cooperate with a ridge member included in one or more tracks of a vibratory bowl.

Each element proceeds along the side walls of a vibratory feed bowl as shown in A. The contacts of each element ride on the walls as shown in C and
D. As each element encounters a ridge element in the track, it is sorted according to those chips having a clear path that is in alignment with the ridge member. Those elements without a clear path in alignment are raised above the track by the ridge member, as in E, and fall by gravity to the center of the vibratory bowl for another try.

Those elements that are properly oriented with respect to the ridge member proceed to an end of track stop as shown in F which permits the elements of various sizes to be picked up by vacuum probe apparatus not shown. The vibratory b...
