Description
アルミナセラミックからなる大型の絶縁基板1を用意する。当該大型の絶縁基板1の片面には縦横に分割用の溝が設けられており、かかる分割後の最小単位の絶縁基板1が単位電子部品を構成する。その溝を有する大型の絶縁基板1面に回路素子等を形成していく過程を、図2を参照しながら以下に説明する。かかる図面では、前記最小単位の絶縁基板1について示している。
第11の工程は、上記第1の工程(図2(a)乃至図2(e))と同条件で実施する。そして上記第2の工程と同様に第1の導電性樹脂ペーストをスクリーン印刷により配し(図2(f)、第12の工程)、当該ペーストを硬化させ(第13の工程)、導電性樹脂層12を得る。次いでSn単体からなるハンダペーストをスクリーン印刷により当該導電性樹脂層12上に配しする(第14の工程、図示しない)。次いで上記第3の工程と同様に前記ハンダペースト上にSn単体からなるハンダボールを搭載する(第15の工程)。その後リフロー工程を経てハンダペーストとハンダボールとを固着させる(第16の工程)。その後上記のように、全ての分割用溝を開く方向に応力を付与して分割し、個々の電子部品を得る。
