Abstract
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 () connected to each other by connecting elements () or a connecting support, inserting on the arms () of these first parts () a printed multi-layered plate () having openings for the arms and metal windings ending in at least two contact pads (), 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 () 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 () of said plate are folded against a base () of the core or of the magnetic circuit to from a surface mounting device.
