发明名称 RADIATION ELECTROMAGNETIC WAVE INHIBITION PRINTED CIRCUIT BOARD AND ELECTROMAGNETIC WAVE INHIBITION METHOD
摘要 PROBLEM TO BE SOLVED: To provide a printed circuit board and the inhibition method of leaked electromagnetic waves that can effectively inhibit the leaked electromagnetic waves from a printed circuit board and do not become disadvantageous since the packaging of parts is not limited. SOLUTION: In this radiation electromagnetic wave inhibition printed circuit board, dielectric constant differs depending on a position on a flat pattern.
