Description
本発明の配線回路基板の一実施形態である配線回路基板1を、図1および図2を参照して説明する。
以下の各変形例において、上記した第1実施形態と同様の部材および工程については、同一の参照符号を付し、その詳細な説明を省略する。また、各変形例は、特記する以外、第1実施形態と同様の作用効果を奏することができる。さらに、第1実施形態およびその変形例を適宜組み合わせることができる。
図1および図3A参照に示すように、絶縁層2と、複数の配線3とを備える配線回路基板15を準備した。
抑制部5の形状、寸法等を表1に従って変更した以外は、実施例1と同様に処理して、磁性配線回路基板1を得た。
図3Bに示す、抑制部5を形成する前(製造途中)の磁性配線回路基板1をそのまま比較例1の磁性配線回路基板1として得た。
磁気的結合の抑制(インダクタンスの第1変化率および第2変化率)
実施例1、2および比較例1の磁性配線回路基板1のそれぞれにおける第2の配線3Bにおける第1配線41および第2配線部42の第2方向一端部を、インピーダンス・アナライザ(Agilent社製:4294A)に接続して、第1の配線3に隣接する他の配線3のインダクタンスを測定し、このインダクタンスを参照インダクタンスとした。
磁気的結合の抑制(インダクタンスの変化率)
実施例1、3、4および比較例1の磁性配線回路基板1の第2変化率のおよびそれに対応するインダクタンス密度を求め、これらを、図12に示す。
図11に示すように、実施例1、2および比較例1を比べると、抑制部5を備える実施例1および2は、それを備えない比較例1に比べて、配線3間の磁気的結合の影響が小さいことが分かる。
図12に示すように、実施例1、3および比較例1を比べると、W/Sが0から0.4に近接するにつれて、配線3間の磁気的結合の影響がより小さいことが分かる。
