Abstract
Description
一般的な銅箔の製造
電解銅箔を製造するためのシステムは、金属カソードドラム及び不溶性金属アノードを含んだ。前記金属カソードドラムは回転可能であった。このシステムにおいて、不溶性金属アノードは、金属カソードドラムのほぼ下半部に配置され、当該金属カソードドラムを囲んだ。金属カソードドラムと不溶性金属アノードとの間に硫酸銅電解液を流させ、両者の間に電流を印加して、銅イオンを金属カソードドラムに吸引させて還元され、金属カソードドラムに銅を電着させることにより、電解銅箔を形成し、所定の厚さを得るとき、電解銅箔を金属カソードドラムから分離することにより、連続的な電着で電解銅箔を製造した。
銅線を硫酸水溶液(50重量%)に溶解させ、320g/Lの硫酸銅(CuSO4・5H2O)と100g/Lの硫酸とを含む硫酸銅電解液を製造した。前記硫酸銅電解液に20mg/Lの塩素イオン濃度を提供するために、塩酸(RCI Labscan会社から取得)を添加した。また、硫酸銅電解液に0.35mg/Lのゼラチン(DV、Nippi会社製)を添加した。
粗化処理の第1工程において、上記のように電解銅箔を製造した後、酸性溶液を使用して電解銅箔を洗浄した。洗浄工程では、130g/Lの硫酸銅と50g/Lの硫酸とを含む溶液が充填している酸洗浄容器を使用し、溶液の温度を約27℃に維持させた。電解銅箔を酸洗浄容器に入れ、前記溶液に30秒間浸すことにより、表面の油、脂肪及び酸化物を除去した。その後、電解銅箔を水でリンスした。

・容積パラメータ
銅箔の実体体積(Vm)は、ISO 25178−2:2012に基づいて、レーザー顕微鏡の表面テクスチャ解析を用いて測定した。前記レーザー顕微鏡は、Olympus社製のLEXT OLS5000−SAFであり、画像は、空気温度24±3℃及び相対湿度63±3%で撮られた。
酸素/水素/窒素アナライザ(EMGA−930、Horiba Ltd.)を使用し、非分散型赤外線(non−dispersive infrare、NDIR)検出器と合わせて、表面処理銅箔の酸素含有量と水素含有量を検出した。
引張強度は、IPC−TM−650に従って測定を行った。表面処理銅箔を200℃のオーブン内に1時間放置した。周囲温度まで冷却された後、表面処理銅箔からサイズが100mm×12.7mm(長さ×幅)である試料を切り取った。島津製作所株式会社のAG−I型試験機を用いて、チャック距離50mmとクロスヘッド速度50mm/minの条件で、周囲温度(約25℃)で試料の引張強度を測定した。
ストリップライン(strip−line)構造を使用して、伝送特性を評価した。樹脂に銅箔を貼り付け、さらにストリップラインに製造し、このストリップラインをソース電極として使用した。樹脂(S7439G、SyTech Corporationで製造される)の厚さは152.4μmであり、IPC−TM 650 No.2.5.5.5による10GHz信号の測定において、誘電率(Dielectric Constant、Dk)は3.74であり、誘電損失(Dielectric Loss、Df)は0.006であった。前記ストリップラインの長さは100mmであった。
A:伝送損失の数値が−0.75dB/inを超え、例えば、−0.75dB/inと0dB/inとの間にある場合は、良好とする。
B:伝送損失の数値が−0.75dB/in〜−0.8dB/inの範囲内にある場合は、中等とする。
C:伝送損失の数値が−0.8dB/in未満である場合は、劣等とする。
プレッシャークッカー試験(Pressure cooker test、PCT)は信頼性試験であり、製品の高温、高圧と高湿度条件に耐えられる能力を評価するための試験である。この試験は、回路板のような樹脂封止デバイスがリフローはんだ付けにおける耐熱性の評価に寄与する。また、厳しい環境で試験を行うことにより、耐湿性を評価できる。回路板工程のリフローはんだ付けにおいて、加熱を行うことにより引き起こされた樹脂割れの形成は、加速試験により予測できる。また、製造された部品(例えば、回路板又は回路板の製造に使用されるプレハブボード)の貯蔵及び運送における予想表現への予測も提供できる。
A:同じラミネート体に50回を超えるはんだ浴試験を施した後、そのラミネート板が無効にならない場合は、良好とする。
B:同じラミネート体に10〜50回のはんだ浴試験を施した後、そのラミネート板が無効になった場合は、中等とする。
C:同じラミネート体に10回未満のはんだ浴試験を施した後、そのラミネート板が無効になった場合は、劣等とする。
表1には、特定のVmで作られた銅箔を示す。表記されたデータは、表面処理銅箔の伝送損失に対するVmの影響を例示的に説明する。指標は、上記及び表に示されるA、B及びCである。これらのデータの検討によると、Vmが伝送損失の制御を提供することを示す。例えば、実施例1〜14において、Vmは1.90μm3/μm2未満であった。これらの実施例において、伝送損失のレベルはA又はBであった。比較するために、実施例15〜17のVmは2.03μm3/μm2〜2.55μm3/μm2と高く、伝送損失が劣等であった(伝送損失のレベルはCであった)。
