Description
以下、本発明の磁性体の製造方法について、図に示す実施形態に基づいて詳細に説明する。なお、以下の説明では、実施形態に用いる図面について同一の構成要素には同一の符号を付し、かつ重複する説明は可能な限り省略する。
図1は、実施形態に係る磁性体の製造方法によって製造される磁性体10を説明するために示す図である。
磁性体10は、図1に示すように、絶縁磁性粉末MPを押圧成形した磁性部12と、磁性部12の表面に形成され所望パターンを有する配線13と、磁性部12の裏面に設けられた電極14と、電極14及び配線13を電気的に接続する接続子16とを備える表面実装型のインダクタである。
図2は、実施形態に係る磁性体の製造方法を説明するために示すフローチャートである。
第1工程S10は、シート状の基材1と、基材1上に形成され基材1から離脱可能な配線13とを有する配線基材4を準備する工程である。
第2工程S20は、成形空間中に絶縁磁性粉末MPを堆積した後、絶縁磁性粉末MPの表面に、配線13が対向するように配線基材4を配置し、これらを押圧成形する工程である。
第3工程S30は、固化した絶縁磁性粉末MPの表面から配線13を残して基材1を取除く工程である。
第4工程S40は、磁性部12に接続子16を取り付けるとともに、ICチップ17、コンデンサ、抵抗などの電子部品を搭載する工程である。
次に、配線の平均表面粗さと、配線の密着度との関係を明らかにするために、配線の引き剥し強度試験(ピール強度試験)を行った。
実施形態に係る磁性体の製造方法における第1工程10〜第3工程S30までと同様の方法を用いて磁性体を形成した。磁性体の寸法は、縦10mm×横10mm×高さ2mmである。また、配線の幅は3mmであり、配線の厚さは75μmである。絶縁磁性粉末MPとしては、表面がシリカ膜に被覆された鉄粒子からなる絶縁磁性粉末を用いた。絶縁磁性粉末MPの平均粒径は5μmである。
配線として平均表面粗さRaが6μmの銅箔を基材上に形成した配線基材(図8(a)参照。)を用いて磁性体を作製し、試料Aとした。
配線として平均表面粗さRaが2μmの銅箔を基材上に形成した配線基材(図8(b)参照。)を用いて磁性体を作製し、試料Bとした。
引き剥し強度試験においては、1分に1mmの引き剥し速度で、配線を上方に引っ張りながら配線を磁性部から引き剥していくのに必要な引っ張り力を測定する。
