Description
V=πr2h
V=π(r+Δr)2(h-Δh)
1-(Δh/h)={1/(1+Δr/r)}2
そして、その式に基づいて下記の関係式が導き出される。
Δh/h≒2(Δr/r)
この関係式におけるΔh/hは、円筒形状の導電性樹脂ペースト137の元の高さに対する導電性樹脂ペースト137の高さの減少量である。つまり、Δh/hは、円筒形状の導電性樹脂ペースト137の高さの減少率である。一方、Δr/rは、円筒形状の導電性樹脂ペースト137の元の半径に対する導電性樹脂ペースト137の半径の増加量である。つまり、Δr/rは、円筒形状の導電性樹脂ペースト137の半径の増加率である。このことから、円筒形状の導電性樹脂ペースト137の半径の増加率は、円筒形状の導電性樹脂ペースト137の高さの減少率の半分であることが解る。つまり、例えば、円筒形状の導電性樹脂ペースト137の高さが元の高さの2割に相当する距離、低くなっても、円筒形状の導電性樹脂ペースト137の半径は元の半径の1割に相当する距離しか広くならない。これにより、電子部品138が押し付けられた際の導電性樹脂ペースト137の左右方向への広がりが抑制される。このように、導電性樹脂ペースト137の体積を示す数式を用いて、導電性樹脂ペースト137の左右方向への広がりの抑制を説明することができる。
