A positioning system for electrical components to be mounted on a carrier includes establishing a first reference system and bringing the carrier on which the components are to be mounted to a predetermined position in relation to the first system. The locations for the articles to be mounted on the carrier are defined. A second reference system is established with respect to the first reference system and the carrier is positioned in relation to the articles to be mounted on the carrier using the second reference system. Each reference system is defined by at least three fixed points against which the carrier comes to bear and the points of the second reference system duplicate the points of the first reference system so that the carrier is in the exact position to enable the components to be mounted at the exact predetermined location. |
