Abstract:
A method for manufacturing a modular designed, multilayer connecting substrate having inner and outer layers with electrical and/or optical multiple functions, said multilayer connecting substrate being formed from a plurality of substrate elements, comprising the steps ofseparately fabrication and independently testing a signal conducting substrate element (19), a power supplying substrate element (2), a thermally conductive substrate element (20) and mechanical substrate elements (7),mounting components on the signal conducting substrate element (19) and on the power supplying substrate element (2), and,assembling the multilayer connecting substrate by:placing the signal conducting substrate element (19) and power supplying substrate element (2) as inner layers of the multilayer connecting substrate,placing the mechanical substrate elements as outer layers of the multilayer connecting substrate so as to provide mechanical stiffness to the multilayer connecting substrate and protection for the inner layers, andthermally connecting the signal conducting and power supplying elements (19, 2) to the thermally conductive substrate element (20) so as to convey heat from the inner layers to the outer layers.
