ELECTRIC DEVICE MODULE

摘要

PURPOSE: An electric element module is provided to be cost-effectively manufactured by reducing the number of layers required to supply signals to the electric element module. CONSTITUTION: A first contact-pad region(110) and a second contact-pad region(120) are arranged on both sides of a module board. The arrangement of both contact-pad regions has a mirror shape. The first contact-pad region and the second contact-pad region include a plurality of contact-pads(P11' to P16'). A first via region includes a plurality of vias(V1 to V6) which is formed between the first contact-pad region and the second contact-pad region.
