Abstract

A printed board comprising a plurality of through holes formed therein and located on intersecting points of an X-Y orthogonal basic grid, and an oblique conductor pattern, wherein conductors are formed along channels arranged in accordance with a principle that one conductor passes between adjacent grid points arranged in the X direction, while two or more conductors pass between adjacent grid points arranged in the Y direction, and each conductor obliquely extends in a zigzag line without contacting the grid points. Such conductor pattern ensures a high density and minimum length of wiring.
