Abstract:
A method of obtaining a module including at least one inductive winding made up of a plurality of aligned modular printed circuit film elements that are combined to form the at least one inductive winding, which method includes the following steps:forming a stacked assembly by stacking the plurality of aligned modular printed circuit film elements, each of the plurality of modular printed circuit film elements carrying a set of turns of one or more conductive tracks which form part of the at least one inductive winding, and wherein the one or more conductive tracks terminate at or near an edge of the modular printed circuit film element, molding an insulative material over the stacked assembly of modular printed circuit film elements to constitute a rigid block, cutting the rigid block laterally along the stacked assembly to expose an end for each of the one or more conductive tracks at a common alignment level and so that the exposed ends from the plurality of modular printed circuit film elements are flush with a surface of one face of the block, which cutting step is performed at least once, and creating connections on the one face of the block with which the exposed ends are flush to selectively interconnect the one or more conductive tracks and to connect the one or more conductive tracks to connection means external to the module.
