Description
また、開口部は、線状のスリットを含む。それにより、金属層の面積を十分に確保することができる。そのため、金属層による放熱性を十分に確保することができる。
(3)スリットの幅は、50μmよりも大きく500μmよりも小さくてもよい。
また、開口部は、線状のスリットを含む。それにより、金属層の面積を十分に確保することができる。そのため、金属層による放熱性を十分に確保することができる。
on film)用の基板(以下、COF基板と呼ぶ)について説明する。
図1は本発明の参考形態に係るCOF基板の断面図であり、図2は本発明の参考形態に係るCOF基板の平面図である。なお、図2(a)は図1におけるCOF基板の上面を示し、図2(b)は図1におけるCOF基板の下面を示す。また、図2(a)および図2(b)のA−A線断面が図1の断面に相当する。
電子部品5の熱圧着時または駆動時においては、COF基板100の絶縁層1および金属層3に熱が加わる。それにより、絶縁層1および金属層3が熱膨張する。この場合、剛性が高い金属層3の膨張に追従するように、絶縁層1が膨張する。
次に、参考形態に係るCOF基板100の製造方法の一例を説明する。図5および図6は、参考形態に係るCOF基板100の製造方法について説明するための工程断面図である。なお、図5および図6に示す断面は、図2のB−B線断面に相当する。
参考形態では、電子部品5に対向する領域を横切って金属層2を分断するようにスリット3aが形成される。それにより、端子部21に加わる応力が全体的に緩和される。その結果、電子部品5のバンプ5aと導体パターン2の端子部2aとの接続性が向上される。
(5−1)参考例
次の条件でCOF基板100を作製した。
金属層3にスリット3aを形成しない点を除いて上記参考例と同様にCOF基板100を作製した。
参考例および比較例のCOF基板100に熱圧着により電子部品5を実装した。なお、実装時のツール温度を430℃とし、ステージ温度を100℃とし、実装荷重を30Nとした。ここで、ツール温度は、導体パターン2の端子部21または電子部品5のバンプ5aの加熱温度であり、ステージ温度は、電子部品5の実装時にCOF基板100が載置されるステージの温度である。
金属層3に形成されるスリット3aの配置および形状は上記の例に限定されない。図7および図8は、金属層3に形成されるスリット3aの変形例を示す図である。
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。
絶縁層1の材料は、ポリイミドに限らず、ポリエチレンテレフタレート、ポリエーテルニトリル、ポリエーテルスルフォン等の他の絶縁材料を用いてもよい。また、導体パターン2の材料は、銅に限らず、銅合金、金、アルミニウム等の他の金属材料を用いてもよい。
