Description
まず、スルファミン酸ニッケルめっき液を用いて、厚さ0.3mmの黄銅(C2600)からなる素材上に、下地めっきとして厚さ1μmのニッケルめっき層を形成した。
ニッケルめっき層と複合めっき層の間に錫めっき層を形成しなかった以外は、実施例1〜9と同様の方法により、それぞれ表1に示す膜厚の錫と黒鉛粒子の複合めっき層が形成された複合めっき材を作製し、複合めっき材の複合めっき層中の炭素の含有量および複合めっき材の摩擦係数を算出するとともに、接触抵抗を測定した。その結果、表1に示すように、炭素の含有量は0.91〜1.56重量%、摩擦係数は0.13〜0.17、初期の接触抵抗は0.88〜1.12mΩ、85℃で湿度85%の環境下で14日間放置後の接触抵抗は3.61〜20mΩ以上であった。特に、85℃で湿度85%の環境下で14日間放置後の接触抵抗は、比較例1および2では、それぞれ17.6mΩおよび20mΩ以上まで上昇し、比較例3および4では、それぞれ3.6〜3.7mΩであり、実施例1〜9と比較して上昇していた。
複合めっき膜を形成しなかった以外は、実施例1〜9と同様の方法により、それぞれ表1に示す膜厚の錫めっき層が形成された錫めっき材を作製し、錫めっき層中の炭素の含有量および錫めっき材の摩擦係数を算出するとともに、接触抵抗を測定した。その結果、表1に示すように、炭素の含有量は0.17重量%未満〜0.73重量%未満、摩擦係数は0.24〜0.33、初期の接触抵抗は0.89〜1.11mΩ、85℃で湿度85%の環境下で14日間放置後の接触抵抗は0.57〜6.11mΩ以上であった。

Claims (5)
- 素材上に下地めっき層として厚さ0.5〜2.44μmの錫めっき層が形成され、この錫めっき層上に、錫層中に炭素粒子を含有する複合材からなる厚さ0.5〜2.53μmの複合めっき層が形成されていることを特徴とする、複合めっき材。
- 前記複合めっき材を85℃で湿度85%の高温高湿環境下で14日間放置した後の接触抵抗が6.5mΩ以下であることを特徴とする、請求項1に記載の複合めっき材。
- 前記複合めっき層中の炭素粒子の含有量が0.1〜2.0重量%であることを特徴とする、請求項1または2に記載の複合めっき材。
- 素材上に厚さ0.5〜2.44μmの錫めっき層を形成した後、炭素粒子を添加した錫めっき液を使用して電気めっきを行うことにより、錫層中に炭素粒子を含有する複合材からなる厚さ0.5〜2.53μmの複合めっき層を前記錫めっき層上に形成することを特徴とする、複合めっき材の製造方法。
- 雌端子とこの雌端子に嵌合する雄端子とからなり、雌端子と雄端子の少なくとも一方の少なくとも他方と接触する部分が、請求項1乃至3のいずれかに記載の複合めっき材からなることを特徴とする、接続端子。
