Abstract

A method for manufacturing a modular electrical circuit includes the steps of pre-manufacturing a plurality of components having fine features such as resistors, capacitors, inductances, and conductors formed on a dielectric substrate. The pre-manufactured components are laminated each to the other in a predetermined order. Each pre-manufactured component includes one or more electrical elements of the same type coupled each to the other by conducting lines. Each dielectric substrate includes through vias filled with the conductive material which serve for cross-coupling of the elements of neighboring components. Position of the passive elements, as well as conductive lines and through vias, are pre-designed to allow precise coordination between the elements of different components in the multi-layered modular electrical circuit.
