Method of manufacturing discrete electronic components

The manufacturing method for components of the inductive type, in particular inductance coils, transformers or antennae, consists in making by micro-machining simultaneously on a first substrate made of magnetic material a plurality of first parts (1) connected to each other by connecting elements (2) or a connecting support, inserting on the arms (8a, 8b, 8c) of these first parts (1) a printed multi-layered plate (4, 5) having openings for the arms and metal windings ending in at least two contact pads (7a, 7b), in placing and securing a second substrate made of magnetic material on the first substrate and the plate, said second substrate having undergone micro-machining to obtain second parts (13) complementary to the first parts. These second parts are connected to each other by connecting elements or a connecting support. Then, the components are separated and, in a particular implementation, the contact pads arranged on tongues (16, 18) of said plate are folded against a base (9) of the core or of the magnetic circuit to form a surface mounting device (SMD).
