Wiring layout of auxiliary wiring package and printed circuit wiring board

Abstract

A printed circuit board wiring system including a printed wiring circuit board having a plurality of conductive layers, at least one electronic part mounted on one side of the circuit board and configured to output signals via signal lines, and an auxiliary wiring package mounted on the other side of the circuit board and including a plurality of conductive layers configured to allow the signal lines from the electronic part to pass therethrough so as to be connected to the circuit board. Further, a first set of signal lines are immediately drawn from the at least one electronic part using half of the plurality of conductive layers of the circuit board without passing through the auxiliary wiring package, and a second set of signal lines are drawn from the at least one electronic part through the circuit board and the auxiliary wiring package using the other half of the plurality of conductive layers of the circuit board.
