To permanently apply lead terminals to corresponding electrodes of electronic or electro-optic components, the following steps are carried out: a. providing a frame including at least one tensioned wire, b. providing a holding jig including at least one seat in which a respective one of the components can be removably and temporarily retained, c. applying the components to the seats with the respective electrodes aligned along a respective longitudinal direction; in this way a row of aligned components is obtained, each component having a corresponding electrode aligned to the subsequent one in the row, d. applying the holding jig to the frame and orienting the same so that the longitudinal direction corresponds to the direction of the tensioned wire, the tensioned wire being thereby brought substantially in contact with (all) the electrode(s) aligned to each other on a corresponding row of components, e. electrically and mechanically bonding the tensioned wire to the corresponding electrodes; in this way all components are simultaneously bonded to the wire, and f. cutting the wire to separate the components from each other thereby forming a respective lead terminal for each electrode.
