Abstract: A probe head includes a plate, a probe, and at least one composite coating layer. The plate has at least one through hole therein. The probe is at least partially disposed in the through hole of the plate. The composite coating layer includes a metal layer and a plurality of lubricating particles. The metal layer is disposed in the through hole of the plate and between the plate and the probe. The lubricating particles are dispersed in the metal layer.

Abstract: A current-diverting guide plate for use in a probe module is disclosed to include a plate body having a first surface, a second surface opposite to the first surface, and a plurality of through holes penetrating through the first and second surfaces. A conducting layer is provided at a periphery wall of each through hole of the plate body and electrically coupled to a probe slidably inserted through the through holes. A current-diverting circuit trace is disposed on the first surface of the plate body and electrically connected with the conducting layers for diverting the electric current flowing through probes. Thus, the current-diverting guide plate can be used to prevent the probes from possible damage due to an excessive instantaneous current.
