Abstract
薄くて大容量のコンデンサ機能を内蔵したプリント配線板を得る。
【解決手段】
コア基板30に内層導体回路32A、32Dを形成する工程と、コア基板30に凹部31を形成する工程と、樹脂モールドされずかつ共通する側に電極を有する平面状のコンデンサ素子20を、凹部31に収容する工程と、これを絶縁樹脂43と導体金属箔44に挟んで加熱加圧して多層板にする工程と、外層導体42Aとコンデンサ素子20の電極21、22を電気的に接続する為のビアホール41Aを形成し、これらに導体層50を形成する工程と、この多層板の表面に外層導体回路42A、42Bを形成する工程から成るプリント配線板の製造方法である。
【選択図】 図1
Description
そのため、部品の小型化が進められると共に、プリント配線板の導体パターンの微細化による表面実装の高密度化が進展している。
また、チップの小型化によりコンデンサの容量が小さくなる為、大容量の要求に対応することが難しくなっている。
これにより、凹部の寸法を樹脂モールドされていないコンデンサの寸法よりわずかに大きくコントロールすることで、高い部品の位置精度が得られ、部品を固定するための樹脂を凹部に充填する必要が無く、工程の削減が可能となる。
プリント配線板は、パッケージされていないコンデンサ素子20と、このコンデンサ素子を収容するコア基板30、及びビルドアップ層40A、40Bから成る。コア基板30はパッケージされていないコンデンサ素子20を収容する凹部31を有し、その表面と内部に複数の導体層32A、32B、32C、32Dを有する。ビルドアップ層40Aにはビアホール41A及び導体回路42が形成されビアホール41Aによって、コア層表面の導体回路32A及びパッケージされていないコンデンサ素子20とビルドアップ層の導体回路42Aが接続されている。また、ビルドアップ層40Bにもビアホール41B及び導体回路42Bが形成され、コア層表面の導体回路32Dとビルドアップ層の導体回路42Bが接続されている。
なお、本実施形態では、ビルドアップ層40A、40Bは1層から成っているが、複数のビルドアップ層から構成することもできる。
なお、図2に示したコンデンサ素子20は、平板状のベース金属23の両側(上下面)に、第1電極21及び第2の電極22を形成しているが、ビアホール41Aに接続されるのは上側だけなので、図10に示すように、コンデンサ素子の一方側のみにこれらの電極21,22を形成するようにしてもよい。
先ず、図3において、コア層となるプリント配線板(コア基板30と言う)を形成する。コア層の材質はプリント配線板用に用いられるものであれば、特別に制限されるものではない。
本実施形態では、電気銅めっきにビアフィリング用めっき液を用いることで電気銅めっきによりビアホール表面を平坦としたが、樹脂充填を行う場合は、電気めっき後に樹脂充填を行うことでビアホール表面を平坦にすることができる。この場合、ビアホール上には充填樹脂が露出するため、はんだ接続などが行われる場合には樹脂充填後に再び電気銅めっきを行う必要がある。
22 第2電極、 23 ベース金属、
24 誘電体層、 25 導電性高分子膜
30 コア基板、 31 凹部、
32A,32B,32C,32D コア層の導体回路、
40A,40B ビルドアップ層、
43 層間絶縁樹脂、 33 凹加工の基準面測定用導体、
41A ビアホール、 42A、42B 外層導体回路、
44 銅箔、 45 スルホール穴、 50 銅被膜
