Abstract
【解決手段】セラミック基材の片側に導体パターンが形成されたセラミック基板と、前記セラミック基板の導体パターンとコネクタを兼ねるイグナイタケースにインサート成形された端子の間がアルミワイヤボンディングで電気的に接続され、前記セラミック基板上に形成される導体パターンにアルミワイヤボンディングが直接なされるイグナイタにおいて、アルミワイヤボンディング部の導体パターンの下にセラミック基材の表裏を貫く穴が形成され、穴の内部に金属が充填される。
【選択図】図10
Description
すなわち図6に示すように2ndボンド後にワイヤボンダのツール32が矢印33の方向に移動すると、器状に成形されているイグナイタケースに接触しワイヤボンディングができない懸念が生じる。
よって、あらかじめツールの移動量を考慮したデッドスペースがコネクタ設計に反映されている。
特に重量の軽減についてエンジンは小型化の方向にあり、点火コイルには更なる小型化によるエンジン搭載性の向上が求められる。

55 アルミワイヤ
