Description
本発明の熱式空気流量計の一実施例である第1実施例について説明する。図1に示すように、センサアセンブリ10はリードフレーム1、ガラスプレート2、LSI3、センサチップ4を備えており、これらが第1樹脂7で覆われている。リードフレーム1にガラスプレート2を樹脂フィルム5を用いて接着し、このガラスプレート2にLSI3とセンサチップ4を樹脂フィルム6を用いて接着する。LSI3とセンサチップ4との間、LSI3とリードフレーム1との間は、金線8、9によってワイヤボンデングにより結線することで電気的に接続される。これらを熱硬化性の第1樹脂7によりモールドし、センサアセンブリ10を製作する。なお、LSI3は、流量検出部となるセンサチップ4からのアナログ信号をデジタル信号に変換し、制御、出力する。
熱式空気流量計の第2実施例について説明する。なお、センサアセンブリ10及びハウジング11の構造は上記実施例1と同様の構造である。
熱式空気流量計の第3の実施例について説明する。センサアセンブリ10及びハウジング11の構造は上記実施例1と同様の構造である。実施例3では、図7に示すように、LSI3内部の拡散抵抗体をポリシリコン抵抗18に変更したものである。
