Description
奇数パッドは、順に(0,0)(0.45,0)(0.90,0)...
偶数パッドは、順に(0.225,0.13)(0.675,0.13)(1.125,0.13)...
とした。また、図示しない内層配線は、表層配線16の各奇数パッドと同じx座標でビア15で表層に立ち上げ、
パッド位置は、順に(0,0.26)(0.45,0.26)(0.90,0.26)...
とした。入出力用パッドは、それぞれ0.15mm角で、間隔は、簡単な計算で得られるように、それぞれ0.26mmである。これらの値は、後述するPCB基板とワイヤボンディングするのに対して、十分な値である。また、間隔が一定とは、すなわち各パッドは正三角形の頂点の位置に配置していることである。これは、パッド間隔は一定値以上確保した上で、パッドをもっとも稠密に配置できるからである。
図4のセラミック基板3の入出力用パッド2の配置は、実施例1に記載した稠密配置である。また、PCB基板13の入出力パッド31は、セラミック基板3側に比べ余裕があり、パッドは、それぞれ0.15mm角で、ピッチは、それぞれ0.26mmで、y軸方向に2列配置とした。
図5の、セラミック基板3のパッド2の配置は、実施例1で同じx軸位置の表層配線16の奇数パッドと、内層配線のパッドとの、x座標をパッドのx軸中心の右側と、左側とで逆方向にずらしている。具体的には、1番パッドのx座標を0.60mm、3、2、14番パッドを0.45mm、5、4、15番パッドを0.30mm、7、6、16番パッドを0.15mm減らし、9、10、17番パッドを0.15mm、11、12番パッドを0.30mm、13番パッドを0.45mm増加する。
