Description
また、絶縁フィルムの周縁側の着設部の面積を大きくする場合に、着設部に着設する半田の厚さを、周縁側の着設部とその他の着設部とで略均一にする。これにより、配線基板の半田バンプと圧電素子の端子との接続状態にバラツキが生じにくい。
また、複数の着設部による着設部配設領域の周囲の少なくとも四隅に、面積の大きい着設部を設ける。これにより、絶縁フィルム及び圧電素子の接続を破壊する外力が加わりやすい四隅の接続強度が高まる。また、周縁側の着設部を、絶縁フィルム上の配線が延在する方向に長い長円形とした。これにより、配線基板をインクジェットヘッドに搭載するときに、駆動ICの接続部及び圧電素子の接続部の間で折り曲げた場合に加わる外力に対する強度を高める。
