Description
式1は、長方形ダクトで流体の摩擦損失(friction loss)を求めるための方程式である。液晶パネル200に実装された駆動IC100のバンプBが形成する空間を長方形ダクトでモデリング(modeling)すると、下記の式2が得られる。
ここで、EfはACF700の単位質量当たりの摩擦損失エネルギーであり、LはバンプBの第1長さL1、Deは等価直径(Equivalent Diameter)、Vは検査領域CA内で流動するACF700の平均流速、fは摩擦因子(friction factor)、ef1は検査領域CAの入口Enで発生する入口損失に関する係数(entrance loss coefficient)、ef2は検査領域CAの出口Exで発生する出口損失に関する係数(exit loss coefficient)である。
ここで、LはバンプBの第1長さL1、W1は同一の列に配列され互いに隣接するバンプBの間隔、HはバンプBの高さを意味する。
