Description
(i) 少なくとも1つの非導電性基層、
(ii) 上記基層(i)の表面上に施された少なくとも1つの銅および/または銅合金層、および
(iii) 少なくとも1種の導電性重合体を含有する層。
(1) 銅または銅含有合金の層を基層の表面上に適用し;
(2) 工程(1)で製造した層を構造化し;
(3) 構造化した銅または銅合金層上に、少なくとも1種の導電性重合体と銅を錯化できる少なくとも1種の錯化剤とを含有する層を施す。
エポキシ樹脂複合体プリント配線基板を、洗浄浴において45℃で2分間硫酸およびクエン酸をベースにした通常の市販洗浄剤(ACL7001,オルメコン社)を用いて洗浄・脱脂した。このプリント配線基板は試験設計(図1参照)を持ち、この試験設計は試験機関およびプリント配線基板メーカのものと一致し、実際のプリント配線基板構造を模したものであった。これらの基板は、はんだ付け性が測定可能で、評価可能であった。次に、プリント配線基板を室温の水道水で水洗いし、その後、H2O2含有エッチング液(エッチ7000,オルメコン社)で2分間30℃で処理した。エッチング後、基板を再び室温の水道水で水洗いし、その後、表1に示した導電性有機重合体で被覆した。そのためには、基板を、当該重合体の水性分散液に室温で1分間浸漬した。その後、プリント配線基板を45〜75℃で乾燥した。
実施例1〜2と同様に、プリント配線基板をベンゾトリアゾール系の通常の市販品(グリコートタフエース F2(LX),四国社,日本,実施例3;およびエンテックプラスCu 106A,エンソンOMI社,オランダ,実施例4)によりそれぞれの取扱説明書にしたがい被覆した。
実施例1〜4で製造したプリント配線基板の幾つかを促進老化法に付した。この方法においては、幾つかの基板を100℃で1時間貯蔵し、その他の基板は144℃で4時間貯蔵した。新たに作製した基板と100℃または144℃で老化させた基板のはんだ付け角度(濡れ角度: NF A 89 400 PまたはANSI−J−STD 003 I.E.C. 68−2−69の基準に準拠)を通常の市販メニスコグラフ計(ST60型,メトロンエレック社)で測定した。この装置は、濡れ力を時間の関数として測定し、その数値を通常の手順ではんだ付け角度に換算するものである(説明書を参照)。いずれの場合も、はんだ付け角度をリフローサイクルなしと、リフローサイクル2回の後と、リフローサイクル3回の後に測定した。リフローサイクルは、繰返しのはんだ付け操作のシミュレーションに役立ち、HA 06 ホット−エア/クォーツ リフロー オーブン(C.I.F./アセレック社、フランス)で実施した。この装置は温度プロフィールにより
多数回のはんだ付けをシミュレートする。
試験設計(図1)のエポキシ樹脂複合体Cuプリント配線基板を、洗浄浴において45℃で2分間硫酸およびクエン酸をベースにした通常の市販洗浄剤(ACL7001,オルメコン社)を用いて実施例1にしたがい洗浄・脱脂した。次に、プリント配線基板を室温で3回(<1分間)水道水で水洗いし、その後、H2O2含有エッチング液(マイクロエッチ MET7000,濃度:2容量%,オルメコン社)で2分間35℃で処理した。エッチング後、基板を再び室温で3回(<1分間)水道水で水洗いし、その後、導電性ポリアニリン(PA,濃度:0.5%有機金属)の水性分散液で被覆した。そのためには、基板を、この分散液に35℃で約3分間浸漬した。その後、プリント配線基板を脱イオン水(50℃)で3回(<0.5分間)水洗いし、充分に乾燥させた。この処理の後、プリント配線基板には厚さ100〜200nmの薄く均一で平坦な透明被覆があった。次に、実施例5に記載した方法ではんだ付け角度を測定した。結果を表3に示す。従来法でスズ(Sn)を被覆したプリント配線基板を対照とした。
