Description
次に、図1(D)に示すように、切欠き部15、16にクランプ(図5(B)参照)を入れて、樹脂漏れ防止テープ13を直接挟持し、徐々に樹脂漏れ防止テープ13を剥がす。樹脂漏れ防止テープ13は剥離起点部17の近傍にめっき19がなされているので、容易に剥離し、リードフレーム10に永久変形を与えない。
このリードフレーム27において、最終的に樹脂漏れ防止テープ13を剥ぐ工程は、第1、第2の実施の形態に係るリードフレーム10、23と同じである。
Claims (5)

前記接合強度を弱めた領域は、前記リードフレーム本体の裏面に形成されためっきによって構成されていることを特徴とするリードフレーム。 - 所定形状に加工されたリードフレーム本体の裏面に樹脂漏れ防止テープが貼着されたリードフレームにおいて、前記リードフレーム本体の端部にディテープの起点となる切欠き部を形成し、かつ前記リードフレーム本体の裏面で前記切欠き部の周囲に、前記樹脂漏れ防止テープと前記リードフレーム本体との接合強度を弱めた領域を設け、
前記接合強度を弱めた領域は、前記リードフレーム本体の裏面に形成された凹状薄肉部によって構成されていることを特徴とするリードフレーム。 - 請求項1又は2記載のリードフレームにおいて、前記接合強度を弱めた領域は、前記リードフレーム本体の前記切欠き部の切欠き端部から0.05〜2mmの隙間を有して形成されていることを特徴とするリードフレーム。
- 請求項1〜3のいずれか1記載のリードフレームにおいて、前記接合強度を弱めた領域は、0.05〜3mmの幅を有することを特徴とするリードフレーム。
- 端部にディテープの起点となる切欠き部が形成さたリードフレーム本体の裏面に樹脂漏れ防止テープが貼着されたリードフレームの製造方法において、前記樹脂漏れ防止テープを前記リードフレーム本体に加熱貼着するヒータプレートの前記切欠き部及び前記切欠き部の周囲に相当する部分に、前記樹脂漏れ防止テープと前記リードフレーム本体との接合強度を弱める凹部を設けたことを特徴とするリードフレームの製造方法。
