Probe, printed circuit board testing device and printed circuit board testing method

摘要

A probe is mountable to a printed circuit board testing device which performs a test on a predetermined land and/or a predetermined via hole of a printed circuit board. The probe includes a probe tip and a protrusion. The probe tip is contactable with the land and/or the via hole and projectable from the probe. The protrusion is disposed at a surface of the probe, the surface of the probe being disposed opposite to where the probe tip is projectable. The protrusion is grounded by a reaction pressure that is generated when the probe tip contacts the land and/or the via hole.
