Abstract
【解決手段】各配線パターン2は、導体層2aおよび錫めっき層2bからなり、先端部21、接続部22および信号伝送部23を含む。先端部21の幅と信号伝送部23の幅とは互いに等しく、接続部22の幅は先端部21および信号伝送部23の幅より小さい。電子部品の実装時には、各配線パターン2の接続部22と電子部品の各バンプ61とが熱融着によって接続される。距離A1,A2は、0.5μm以上に設定される。距離B1,B2は、20μm以上に設定される。錫めっき層2bの厚みは0.07μm以上0.25μm以下に設定される。
【選択図】図4
Description
図1(a)は、本実施の形態に係る配線回路基板の平面図であり、図1(b)は図1(a)の配線回路基板のP−P線断面図である。
次に、図1に示した配線回路基板50と電子部品との接続構造について説明する。図2は、配線回路基板50と電子部品との接続構造を示す斜視図である。図3(a)は配線回路基板50と電子部品との接続構造を示す平面図であり、図3(b)は図3(a)のQ−Q線断面図である。
ここで、配線回路基板50の配線パターン2および電子部品60のバンプ61の詳細について説明する。図4は、配線回路基板50の配線パターン2および電子部品60のバンプ61の詳細を説明するための平面図である。
ポリイミドおよび銅箔からなる2層基材を用意し、銅箔を所定のパターンでエッチングすることによってベース絶縁層1上に導体層2aを形成した。次いで、導体層2aの表面を錫めっき層2bによって被覆することにより配線パターン2を形成した。次いで、複数の配線パターン2を覆うようにベース絶縁層1上にカバー絶縁層4を形成し、配線回路基板50を得た。また、電子部品60として、複数の金(Au)バンプを有する半導体チップを用意した。
実施例1〜6および比較例1〜4に示す条件で配線回路基板50の接続部22と電子部品60のバンプ61とを熱融着により接続し、短絡の発生率を調べた。その結果を表3に示す。ここで、短絡とは、図5に示したように、熱融解した錫めっき層2bが隣接する接続部22間で接触する場合をいう。
上記実施の形態では、配線パターン2の信号伝送部23の幅が接続部22の幅より大きく設定されるが、これに限定されない。図6は、配線パターン2の変形例を示す平面図である。図6の例では、配線パターン2の信号伝送部23の幅が接続部22の幅と等しく設定される。なお、信号伝送部23とベース絶縁層1との密着性は、信号伝送部23がカバー絶縁層4で覆われることにより確保される。
以下、請求項の各構成要素と実施の形態の各要素との対応の例について説明するが、本発明は下記の例に限定されない。

2a 導体層
2b 錫めっき層
