Abstract
Abstract A method for making an electronic component, for example, a motor coil. The method comprises the steps of forming a plurality of conductive layers and interconnecting the layers to provide an electrically conductive path between the layers. In order to form interconnections between the layers which have a low electrical resistance and which can be formed in a high-speed automated process, a conductive paste is applied to one of the conductive layers and the layers are superposed to form the interconnections.
