Abstract
Description
以下、本発明の実施の形態について、図面を参照して詳細に説明する。各図面に示される同一または同等の構成要素、部材、処理には、同一の符号を付すものとし、適宜重複した説明は省略する。図1は、本実施形態に係る回路基板100を示す模式斜視図である。回路基板100は、第1基板部11と、第2基板部12と、配線基板30と、レジスト層40とを備えている。
次に、本発明の第2実施形態について説明する。第1実施形態と重複する内容は説明を省略する。第1実施形態では、互いに交差する第1面61と第2面62をブロック状のヒートシンク60上に形成した例を示したが、一枚の平坦な金属板に第1基板部11と第2基板部12を搭載した後に、折り曲げ加工で第1面61と第2面62を形成するとしてもよい。この方法では、互いに交差する面上に第1基板部11と第2基板部12を搭載するよりも、搭載作業を簡便化することができる。
