Abstract

PURPOSE:To achieve high-density mounting and solve problems such as short- circuiting between wiring patterns, by pulling out a wiring pattern coming out from a land with the wiring pattern placed on a lattice. CONSTITUTION:A printed wiring board 10 has lands 14 formed on required nodes 12 of lattices 11. The board 10 also has wiring patterns 15 connected to appropriate lands 14, and a CAD device is used to form a wiring pattern 15 between lattices 11 to form wiring channel 13 between lattices 11. A wiring pattern 15 led out from a land 14 is pulled out while being placed on a lattice 11 and then is bent 45 deg. with respect to an advancing direction. The bent wiring pattern 15 is further bent so as to be carried on wiring channels 13 newly formed in required number between lattices 11 through which the pattern 15 goes.
