Description
該電子部品を少なくとも部分的に被覆するプライマー層と、
上記電子部品及び上記プライマー層を少なくとも部分的に被覆する封止樹脂と、を有し、
上記プライマー層は、下記の式(1)で表される構造を有するポリイミド重合体を含有し、
上記封止樹脂は、エポキシ系樹脂及び/又はマレイミド系樹脂を含有し、
上記封止樹脂は、上記エポキシ系樹脂及び/又は上記マレイミド系樹脂として、エポキシ化合物及び/又はマレイミド化合物を含む主剤と、下記の式(2)で表されるジアミン化合物を含有する硬化剤とを含むモールド材の硬化物を含有することを特徴とする電装部品にある。
電子部品は、SiC基板等からなるパワー素子を有することが好ましい。SiC基板等を用いたパワー素子は、例えば240℃を超える高温環境下に曝されるおそれがあるため、この場合には、電装部品が広範囲の温度領域において優れた耐久性を示すという上述の効果が顕著になる。電装部品としては、例えば車両用、特にハイブリッド車(HV)用のパワーコントロールユニット(PCU)に用いられる半導体モジュール(パワーカード)等がある。
次に、電装部品の実施例について説明する。本例においては、
図1に示すごとく、本例の電装部品1は、電子部品2と、プライマー層3と、封止樹脂4とを有する。プライマー層3は、電子部品2を少なくとも部分的に被覆している。また、封止樹脂4は、プライマー層3及び電子部品2を少なくとも部分的に被覆している。
次に、実施例1とは、プライマー層、封止樹脂の組成が異なる複数の電装部品を作製した。各電装部品は、図示を省略するが、組成を除いては実施例1と同様の構成を有している(図1参照)。実施例2及び3は、実施例1とはジアミン化合物と酸無水物との配合割合が異なるプライマー液を用いた点を除いては、実施例1と同様にして作製した電装部品である。実施例2及び3の作製に使用したプライマー液の組成を後述の表1に示す。
次に、各実施例及び比較例の電装部品の耐久性を評価した。耐久性は熱衝撃試験により評価する。具体的には、まず、各電装部品を温度250℃で30分間加熱し、次いで、温度−40℃で30分間保持するという冷熱サイクルを繰り返し行った。そして、超音波探傷装置を用いて電装部品における封止樹脂の内部剥離の有無を定期的に確認した。1000サイクル以上の熱衝撃試験において剥離がなかった場合を「優」と評価した。100サイクル以上、かつ1000サイクル未満の熱衝撃試験において剥離がなく、1000サイクル以上で剥離が発生した場合を「良」と評価した。また、100サイクル未満の熱衝撃試験において剥離が発生した場合を「不可」と評価した。各実施例及び比較例の熱衝撃試験の結果を表1に示す。
