Abstract
【解決手段】ビア付きインダクタの製造方法は、複数の配線14および複数の配線14を埋設する磁性層15を備えるシート状のインダクタ3を枠部材2の内部にセットする第1工程と、第1工程の後に、配線14の厚み方向一方側に位置する磁性層15に、配線14の厚み方向一方面を露出するビア6を形成する第2工程とを備える。

Description
本発明(3)は、前記第1工程では、複数の前記インダクタを、前記枠部材の内部にセットする、(1)または(2)に記載のインダクタの加工物の製造方法を含む。
本発明の一実施形態により製造されるビア付き積層シートを、図1Dおよび図2Cを参照して説明する。なお、図2Cにおいて、ビア6(後述)の配置および形状を明確に示すために、加工安定層4(後述)を省略している。
そして、このビア付き積層シート1(枠部材付き積層シート21)の製造方法では、図1Bおよび図2Bに示すように、第1工程で、インダクタ3を枠部材2の内部にセットする。そのため、たとえ、インダクタ3が小型であっても、搬送装置で搬送できる寸法を有する枠部材2を用いれば、インダクタ3および枠部材2を搬送装置で確実に搬送でき、ひいては、第2工程で、配線14の間隔や厚みの精度に優れるインダクタ3を、ビア6を形成する装置に搬送して、ビア6を、枠部材2にセットされた磁性層15に確実に形成できる。また、インダクタ3が小型であれば、反りの影響を小さくできる。その結果、この製造方法では、ビア6を、効率よく確実に形成できる。
以下の各変形例において、上記した一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、一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、一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。
