Abstract: A universal multi-pin, adjustable probing assembly or manipulator for use in parametric and reliability testing of devices on a semiconductor wafer. The probing assembly can be mounted and adjusted on a metal platen using a magnetic field. The strength of the magnetic field can be adjusted by a switchable magnetic slab to which a block is connected via an arm. A probe head can be attached to a side face of the block, which includes a tilt control mechanism for tilting the probe head to ensure that probe tips land simultaneously on pads of dies. The probe head also includes four adjusting mechanisms for translation in the X, Y, and Z directions, as well as rotation about the Z axis.
