Description
本発明の第1の実施形態における電子装置は、図1および図2に示されているように、配線基板1と、配線基板1の上面に設けられた電子部品2とを含んでいる。電子装置は、例えば電子部品モジュールを構成する回路基板上に実装される。
ている。メタライズ層12は、電子部品2の搭載部または、電子部品2に例えばワイヤボンディング等によって電気的に接続される接続電極として用いられる。また、メタライズ層12は、タングステン(W),モリブデン(Mo),マンガン(Mn),銀(Ag),銅(Cu)等から選ばれる複数種類の主成分を含んでいる。メタライズ層12は、例えば、CuWを主成分として10〜30μm程度の厚みに設けられる。
m程度の金めっき層とが順次被着される。
ズ層12の最表面には銀めっき層を被着させ、その他のメタライズ層12および配線導体15の最表面には金めっき層を被着させても構わない。金めっき層は、銀めっき層と比較して、電子部品2、接続部材3および外部の回路基板の配線との接合性に優れており、銀めっき層は、金めっき層と比較して光反射率が高いためである。また、配線導体15と金属導体層の最表面を銀と金との合金めっき層として、例えば、銀と金との全率固溶の合金めっき層としてもよい。
層12を形成する。メタライズ層12は、例えば、絶縁基体11となるセラミックグリーンシートに、メタライズ層12用の導体ペーストを所定のパターンに印刷塗布して、絶縁基体11となるセラミックグリーンシートと同時に焼成することによって形成される。例えば、CuWを主成分とするメタライズ層12は10〜30μm程度の厚みに設けられる。
面12aの深さWよりも大きいことが好ましい。ポーラス状の側面12aの周囲の第2のめっき層14の側面に凹凸が発生したとしても、第2のめっき層14の上面は側面と比較して平坦に形成されやすいので電子部品2または接続部材3の接続への影響は小さい。なお、上述のように、第2のめっき層14が複数層からなる場合には、めっき層がはそれぞれ所定の厚みに被着される。
次に、本発明の第2の実施形態による電子装置について、図5を参照しつつ説明する。
11・・・・絶縁基体
12・・・・メタライズ層
12a・・・ポーラス状の側面
