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.
