Description
[第1の実施の形態に係るリードフレームの構造]
まず、第1の実施の形態に係るリードフレームの構造について説明する。図1は、第1の実施の形態に係るリードフレームを例示する図であり、図1(a)は平面図、図1(b)は図1(a)のA−A線に沿う断面図である。なお、図1(a)の平面図において、便宜上、図1(b)の断面図に対応するハッチングを施している。
次に、第1の実施の形態に係るリードフレームの製造方法について説明する。図2〜図8は、第1の実施の形態に係るリードフレームの製造工程を例示する図である。まず、図2に示す工程では、所定形状の金属製の板材10Bを準備する。板材10Bは、個片化領域Cとなる複数の領域を備えている。板材10Bの材料としては、例えば、銅(Cu)や銅合金、42アロイ等を用いることができる。板材10Bの厚さは、例えば、200μm程度とすることができる。なお、図2(a)は平面図、図2(b)は図2(a)のA−A線に沿う断面図である。図2(a)の平面図において、便宜上、図2(b)の断面図に対応するハッチングを施している。
第2の実施の形態では、第1の実施の形態とは異なる製造方法でリードフレームを部分的に薄型化する例を示す。なお、第2の実施の形態において、既に説明した実施の形態と同一構成部についての説明は省略する場合がある。
まず、第2の実施の形態に係るリードフレームの構造について説明する。図9は、第2の実施の形態に係るリードフレームを例示する図であり、図9(a)は平面図、図9(b)は図9(a)のA−A線に沿う断面図である。なお、図9(a)の平面図において、便宜上、図9(b)の断面図に対応するハッチングを施している。
次に、第2の実施の形態に係るリードフレームの製造方法について説明する。図11〜図13は、第2の実施の形態に係るリードフレームの製造工程を例示する図である。
第1の実施の形態の変形例1では、ダムバーを薄型化する例を示す。なお、第1の実施の形態の変形例1において、既に説明した実施の形態と同一構成部についての説明は省略する場合がある。
第1の実施の形態の変形例2では、ダムバーを薄型化する他の例を示す。なお、第1の実施の形態の変形例2において、既に説明した実施の形態と同一構成部についての説明は省略する場合がある。
第1の実施の形態の変形例3では、第1の実施の形態のリードフレーム10Sを得るための他の製造方法の例を示す。なお、第1の実施の形態の変形例3において、既に説明した実施の形態と同一構成部についての説明は省略する場合がある。
まず、図18に示す試験用サンプルを作製した。具体的には、銅からなる平坦な金属板であるリードフレーム材100の上面に、凹部の平面形状が直径0.02mm以上0.060mm以下の円である凹凸部を形成した。そして、凹凸部の表面にめっきを施さないで、凹凸部上に表1に示す作製条件で樹脂カップ140を形成した。なお、6種類のSレシオにおいて、各々6個の試験用サンプルを作製し、6回測定を行った。但し、Sレシオ=1は、凹凸部を形成しない試験用サンプル(比較例:従来品)である。又、Sレシオを求める際の表面積の測定は、3次元測定レーザ顕微鏡(オリンパス社製 LEXT OLS4100)を用いて行った。
銅からなるリードフレーム材100の上面に実施例1と同様の凹凸部を形成し、凹凸部の表面に銀めっきを施し、銀めっきを施した凹凸部上に樹脂カップ140を形成した以外は実施例1と同様にしてカップシェア試験を実施した。なお、銀めっき膜の厚さは約6μmとした。
銅からなるリードフレーム材100の上面に実施例1と同様の凹凸部を形成し、凹凸部の表面にNi/Pd/Auめっきを施し、Ni/Pd/Auめっきを施した凹凸部上に樹脂カップ140を形成した以外は実施例1と同様にしてカップシェア試験を実施した。
銅からなるリードフレームの上面に、凹部の平面形状が直径0.02mm以上0.060mm以下の円であって、Sレシオが1.7以上の凹凸部、すなわち高密度凹凸部を形成することにより、樹脂部と接する部分の表面積が増加する。そのため、アンカー効果が生じ、リードフレームと樹脂部との密着性を向上することができる。
