Description
図1は、この発明に従ったヒートシンクを有するプリント基板を模式的に示す断面図である。プリント基板1は誘電体からなる基材に、第1配線3と第2配線4などの回路を構成する配線パターンおよびスルーホールを有している。この実施の形態では、プリント基板1を多層基板として記載している。
すなわち、条件(7)として電気的損失性を有する回路素子として電気的損失性を有する回路素子1051の抵抗値を22Ωとし、電気的損失性を有する回路素子1052を短絡した解析結果から、ヒートシンク102とプリント基板101間の電界強度値を周波数領域に変換し、上記の(1)の場合と、(2)との場合の解析結果とともにグラフに点線でプロットした図が図6である。(7)を(1)および(2)の解析結果と比較すると、300MHz〜1GHzの帯域で(2)の場合よりも電界強度が増加するものの、(1)のように、ヒートシンクのコンデンサによる自己共振周波数を1GHz以下の帯域で持たないため、機器から発生するEMIを低減することが可能となる。これにより、コンタクトおよび第1の配線を複数有し、少なくとも1ヶ所、電気的損失を有する回路素子で接続した場合に、EMI低減効果があることが確認された。
図8は、参考例に従った集積回路の搭載構造を説明するための図である。図8を参照して、参考例に従った集積回路の搭載構造では、ヒートシンク2を覆うようにシールド部材60が設けられている点で、実施の形態1に従った構造と異なる。導電性を有するシールド部材60と、ヒートシンク2との間には電気的損失性を有する回路素子5が介在している。
