前記制御回路は、配線構造の一部を薄板状のリードフレームにより構成したリードフレーム構造体に、各種ディスクリート部品を接続し、任意に設定されたリードフレームの被固定部をクランパーの固定部により加圧固定してボンディングワイヤの生成・固着を行うことで構成し、
前記制御回路には、少なくとも、
複数の接続部を備えるディスクリート部品であって、複数のリードフレームに跨がって各接続部が接続される架橋部品と、
前記架橋部品の少なくとも1つの接続部が接続される第1リードフレームと、
前記架橋部品の他の接続部が接続される第2リードフレームと、
を含み、
前記ボンディングワイヤの生成・固着に際して、クランパーの固定部により加圧固定される被固定部が設定された第1リードフレームおよび/または第2リードフレームには、架橋部品の接続部と被固定部との間に加圧応力緩和手段を設けたことを特徴とするイグナイタ。 - 前記加圧応力緩和手段は、架橋部品の接続部と被固定部との間を横切るように設けた複数の応力緩和溝であることを特徴とする請求項1に記載のイグナイタ。
- 前記加圧応力緩和溝は、開口面から奥に向かって狭くなる、断面V字状のVノッチであることを特徴とする請求項2に記載のイグナイタ。
- 前記Vノッチの深さTvは、リードフレームの厚さTに対して、0.55T以上としたことを特徴とする請求項3に記載のイグナイタ。
