ABSTRACT:
A manipulator for holding and positioning a test head which is used with automatic test equipment. The manipulator includes a horizontal telescoping member attached to a vertical column. The test head is attached to an assembly suspended from this member. Six planes of free motion of the test head are provided. The column can pivot around a vertical axis. The telescoping member can move up and down along the column and can telescope in and out. The test head assembly can pivot about a vertical axis. Within the assembly, the test head can rotate around two orthogonal vertical axes. This arrangement allows the test head to be positioned into a wide variety of positions. The manipulator includes a set of cable support rings which reduces the forces a cable places on the test head when it is moved. This arrangement allows a prober to be positioned beneath the test head so that the manipulator occupies very little floor space.
