Electric test of the interconnection of electric conductors on a substrate
First Claim
1. A method for establishing an electric current in a conductor between a first point of the conductor and a second point of the conductor that is different from the first point, the method comprising:
- providing, proximate to the conductor, a plate that has a plurality of conductive zones capable of being individually adjusted to any electric potential, and such the at least one conductive zone is located opposite to the conductor, applying a beam of particles to the first point of the conductor to extract electrons from it, without any physical contact with the conductor, the extracted electrons being received by said conductive zone located opposite to the conductor, and at the same time, injecting electrons at the second point of the conductor, producing a circulation of electric current in the conductor between the first point and the second point.

Abstract
To measure the resistance from one end of a conductor (4) to the other or between conductors, for the purpose of testing them, by establishing an electric current in the conductor, without any mechanical contact therewith, this method includes providing opposite and proximate to the conductor (4)a plate (2) that has a plurality of conductive zones (8, 10) capable of being individually taken to any adjustable electric potentials, applying a beam of particles (7) to a first point (C) of the conductor (4) to extract electrons from it, and injecting electrons at a second point (B) of the conductor (4).

9. An electric test method of a plurality of conductors arranged on an insulating substrate, comprising an initial step of arranging, opposite at least one side of the substrate, a plate that has, near each conductor of the substrate, conductive zones capable of being individually adjusted to any electric potential, the method further comprising:
a continuity test step of the conductors of the substrate including, for each conductor of the substrate, establishing a current in the conductor between a first point of the conductor and a second point of the conductor that is different from the first point by providing, proximate to the conductor, a plate that has a plurality of conductive zones capable of being individually adjusted to any electric potential, and such that at least one conductive zone is located opposite to the conductor, applying a beam of particles to the first point of the conductor to extract electrons from it without any physical contact with the conductor, the extracted electrons being received by said conductive zone located opposite to the conductor, and at the same time, injecting electrons at the second point of the conductor, producing a circulation of electric current in the conductor between the first point and the second point and measuring the cat thus established. - View Dependent Claims (10, 11, 12)

13. An electric test device of conductors arranged on an insulating substrate, comprising:
-
at least one source of particles, to emit a beam of particles towards a first point of a selected conductor, so as to t electrons from said selected conductor therefore increase the electric potential of said selected conductor, at least one plate, arranged opposite to one respective side of the insulating substrate, and comprising fit conductive zones, said first conductive zones being capable of being individually adjusted to any electric potential so that a selected one of the first conductive zones located opposite the first point of the selected conductor can receive the extracted electrons without any physical contact between the plate and the selected conductor, means for injecting electrons at any determined second point of the selected conductor on the insulating substrate simultaneous to the electron extraction from said selected conductor, the second point being different from the first point, and a control and measuring station to individually adjust the conductive zones to any electric potential and to measure currents and voltages between a selected two conductive zones. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
