Description
図1は、この実施の形態の発熱源となる電子部品を搭載(あるいは、実装ともいう。)した実装構造を示す、概略断面図である。この実施の形態では、発熱源である電子部品を、半導体チップの外形寸法と実質的に同一の外形寸法を有する半導体パッケージである
WCSP(Waferlevel Chip Size Package)30とし、プリント配線板20に放熱機構を設けた場合を例に挙げて説明する。尚、実質的に同一とは、パッケージの外形寸法が半導体チップの外形寸法と全く同じ寸法である構成はもとより、パッケージの外形寸法が半導体チップの外形寸法に対して20%程度まで大きな寸法となる構成も含まれるという意味である。
図5を参照して、この発明の第2の実施の形態につき説明する。
