Description
電気鍍金研究会編「環境調和型めっき技術」26頁
(1)加熱水蒸気が噴射するノズルまたは接続端子のいずれかを移動させ、この相対的移動により加熱水蒸気を接続端子に全面的に又は必要な箇所に限って走査させる。
(2)加熱水蒸気が噴射により充満されたトンネル内の雰囲気中に接続端子をくぐらせる(トンネル通過方式)。
(3)加熱水蒸気が噴射により充満されるケース内の雰囲気に接続端子を入れ出しする。これは浸漬方法とも言える。
(4)接続端子を予め冷却しておいてから、上記の(1)、(2)、(3)のいずれかにリフロー処理温度に達した加熱水蒸気を当てる。
(5)上記いずれか((1)〜(4))によりリフロー処理の加熱溶融を行った直後に、溶融が深く進行しないように止めるために冷却する。
(6)その他
2 接続端子の基体
3 下地めっき層
4 錫めっき層
5 加熱工程となる加熱トンネル
6 冷却工程となる冷却トンネル
Claims (2)
- 導電性基体の表面に直接または異種金属の下地めっき層を介して錫めっき又は錫合金めっきを施し、この表面錫めっき層が形成された接続端子について、加熱水蒸気の雰囲気中においてその熱により、錫めっき層のみを溶融してなすことを特徴とする接続端子のリフロー処理方法。
- リフロー処理のための前記加熱水蒸気の雰囲気による加熱工程の直後に、不活性ガスの雰囲気により錫めっき層のみに溶融を止める冷却工程を設けることを特徴とする請求項1記載の接続端子のリフロー処理方法。
