Abstract: A vertical probe device includes a lower die having engaging holes and needle holes, a positioning film having limiting holes and needle holes, probe needles inserted through the needle holes, and supporters having at least an upper stopping surface and at least a lower stopping surface for moveably limiting the positioning film therebetween. Each supporter has a head, a neck passing through the limiting hole and having a length longer than the thickness of the positioning film, a body, and a tail inserted into the engaging hole, which are connected in order, and at least one of the upper and lower stopping surfaces. The supporters can prevent the positioning film from being lifted and flipped over and enables the positioning film to move so that the probe needles are reliable.

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.
