Description
図3〜図6は、部品内蔵基板の製造方法による製造工程を示すフローチャートである。また、図7〜図9は、部品内蔵基板を製造工程毎に示す断面図である。まず、図3を参照しながら片面基板30の製造工程について説明する。
まず、図4に示すように、樹脂基材11の両面に導体層が形成された両面CCLを準備し(ステップS200)、所定箇所に上述したようにビアホール2を形成して(ステップS202)、例えばプラズマデスミア処理を行う。
まず、図7(a)に示すように、例えばポリイミドフィルムからなる樹脂基材21の両面に導体層8が形成された両面CCLを準備する(ステップS300)。そして、図7(b)に示すように、エッチングなどを施して両面に配線22を形成する(ステップS302)。
