Description
図1は、第1実施形態に係るセンサパッケージ10の構成を示す斜視図である。図2は、センサパッケージ10の構成を示す分解斜視図である。図3は、センサパッケージ10の構成を示す断面図であり、図1のIII面を、Y方向に沿った矢印III’の方向から見た断面図である。各図には、基準座標としてX−Y−Z座標が示されている。X−Y面はZ方向に直交する面であり、以下の説明において、Z方向を上方向と呼び、Z方向上側から見た状態を平面視と呼ぶことがある。
(1)圧力センサ53を収容するセンサハウジング50とリードフレーム40を保持するメインハウジング30とを別体で形成したため、メインハウジング30、リードフレーム40、及び装置周辺の温度変化の影響がセンサハウジング50の内部空間51内の圧力センサ53まで及びづらくなることから、圧力センサ53の温度特性の精度を維持することができる。また、リードフレーム40とメインハウジング30の樹脂との隙間や界面に残った空気の影響が、センサハウジング50によって遮られるため、圧力センサ53の圧力検知精度を維持することができる。
上述のセンサパッケージ10においては、センサハウジング50とメインハウジング30との間にアンダーフィル材60を配置していたが、アンダーフィル材60を省略して、非導電性の接着剤でセンサハウジング50をメインハウジング30のキャビティ31に固定させてもよい。これにより、センサパッケージ10をより安価に製造することができる。
つづいて、本発明の第2実施形態について説明する。第2実施形態においては、IC基板がセンサハウジングの外部に設けられている点が第1実施形態と異なる。
なお、その他の作用、効果、変形例は第1実施形態と同様である。
