Test head manipulator

A test head manipulator, comprising:

• at least one thrust bearing coupled to a frame;
• a lead screw rotatable about its longitudinal axis in said thrust bearing, where said thrust bearing prevents said lead screw from translating along said longitudinal axis;
• a lead nut threaded onto said lead screw;
• a shaft coupled to said frame in an orientation substantially parallel to said longitudinal axis;
• and
• a linear bearing coupled to said lead nut and slidingly coupled to said shaft, where said linear bearing is configured to slide along said shaft and prevent said lead nut from rotating about said longitudinal axis;
• a carriage configured to couple with an electronic test head;
• and
• at least one cable having a first end coupled to said lead nut, and having a second end coupled to said carriage,
• such that in use when said lead screw is rotated, said lead nut translates along said longitudinal axis, thereby translating said cable and said carriage.

A test head manipulator, comprising:

• at least one bearing coupled to a frame;
• a lead screw rotatable about its longitudinal axis in said bearing;
• a means for preventing said lead screw from translating along said longitudinal axis;
• a lead nut threaded onto said lead screw;
• a means for preventing said lead nut from rotating about said longitudinal axis;
• a carriage configured to couple with an electronic test head;
• and
• a means for coupling said carriage to said lead nut,
• such that in use when said lead screw is rotated, said lead nut translates along said longitudinal axis, thereby translating said carriage via said means for coupling.
