PROCESS OF MANUFACTURING PRINTED WIRING BOARD AND PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a printed wiring board having high connection reliability.SOLUTION: Neighboring opening 71fc for a pad and opening 71fo for a pad are displaced in an axial direction of a wiring part and are disposed so that an opening adjacent to an opening 1 does not exist in a direction perpendicular to the axial direction. Being disposed apart in terms of distance, a short circuit is hardly generated between the neighboring opening 71fc for a pad and opening 71fo for a pad, and connection reliability with an IC chip may be enhanced.
