Description
図5は本発明の第1実施形態のリードフレームを示す平面図、図6は図5のI−Iに沿った断面図、図7は同じくリードフレームを製造するためのパターン状金属板を示す平面図、図8は同じくリードフレームの製造工程におけるグラウンドリングからインナーリードを金型で切り離す様子を示す断面図である。
図11は本発明の第2実施形態のリードフレームを示す平面図である。前述した第1実施形態のリードフレーム1(図5)を製造する際に、ダイパッド10とグラウンドリング14との間隔Sが0.1mm程度以下に設定される場合は、プレス加工やエッチングの最小抜き幅が0.1mm程度であることを考慮すると、グラウンドリング14にダイパッド10側に突出する突出寸法が0.05〜0.1mmの突出部14aを設けることは困難になる。
図13は本発明の第3実施形態のリードフレームを示す平面図、図14は図13のII−IIに沿った断面図、図15は第3実施形態のグラウンドリングの突出部の形成方法を示す断面図である。
