Method of test of the electric conformity of the interconnection of electrical conductors, disposed on a substrate, without contact and without tools

摘要

Method in which a plate (2) with a number of conducting zones (10), that can be raised to selectable voltages, is placed in the proximity of a conductor under test (4). A beam of ultraviolet photons of sufficient energy is targeted at a point (C) on the conductor (4) to eject electrons from its surface. Electrons are then injected into a second point (B) to create a measurable current. An Independent claim is made for a device for testing electrical conductors arranged on an isolating medium.
