〔1〕~〔10〕のいずれか一項に記載のドリル孔あけ用エントリーシートを用いて、積層板又は多層板に孔を形成する、ドリル孔あけ加工方法。
本実施形態のドリル孔あけ用エントリーシート(以下、単に「エントリーシート」ともいう。)は、金属箔と、該金属箔の少なくとも片面に、ポリオレフィン樹脂(A)と水溶性樹脂(B)とを含む樹脂組成物の層と、を有し、前記ポリオレフィン樹脂(A)の含有量が、前記ポリオレフィン樹脂(A)と前記水溶性樹脂(B)の合計100質量部に対して、25質量部以上50質量部以下であり、前記水溶性樹脂(B)の含有量が、前記ポリオレフィン樹脂(A)と前記水溶性樹脂(B)の合計100質量部に対して、50質量部以上75質量部以下であり、前記水溶性樹脂(B)が、重量平均分子量2×105以上、1.5×106以下の高分子量水溶性樹脂(B-1)を含む。
金属箔としては、特に限定されないが、後述する樹脂組成物の層との密着性が高く、ドリルビットによる衝撃に耐え得る金属材料が好ましい。金属箔の金属種としては、入手性、コストおよび加工性の観点から、例えばアルミニウムが挙げられる。アルミニウム箔の材質としては、純度95%以上のアルミニウムが好ましい。そのようなアルミニウム箔としては、例えば、JIS-H4160に規定される、5052、3004、3003、1N30、1N99、1050、1070、1085、8021が挙げられる。金属箔にアルミニウム純度95%以上のアルミニウム箔を用いることによって、ドリルビットによる衝撃の緩和、およびドリルビット先端部との食いつき性が向上し、樹脂組成物によるドリルビットの潤滑効果と相俟って、加工孔の孔位置精度を一層高めることができる。
樹脂組成物の層は、該金属箔の少なくとも片面に配され、ポリオレフィン樹脂(A)と水溶性樹脂(B)とを含む。
ポリオレフィン樹脂(A)としては、特に限定されないが、例えば、オレフィンの単独重合体;オレフィンと、オレフィンと共重合可能な他のコモノマーと、の共重合体が挙げられる。ここで、オレフィンとしては、エチレン、プロピレン、ブチレン、ヘキセン、オクテン等が挙げられる。このなかでも、エチレン、プロピレンが好ましく、エチレンがより好ましい。ポリオレフィン樹脂(A)は、1種単独で用いても、2種以上を併用してもよい。
水溶性樹脂(B)は、水溶性の樹脂であれば特に限定されないが、ポリエチレンオキサイド、ポリプロピレンオキサイド、ポリビニルピロリドン、セルロース誘導体、ポリエチレングリコール、ポリプロピレングリコール、ポリテトラメチレングリコール、ポリオキシエチレンのモノエーテル化合物、ポリオキシエチレンモノステアレート、ポリオキシエチレンソルビタンモノステアレート、ポリグリセリンモノステアレート化合物、ポリエチレンオキサイド-ポリプロピレンオキサイド共重合体、及びそれらの誘導体からなる群より選択される1種類又は2種類以上が好ましい。このような水溶性樹脂(B)を用いることにより、樹脂組成物の層の成型性及びエントリーシートの潤滑材としての効果がより向上する傾向にある。なお、「水溶性の樹脂」とは、25℃、1気圧において、水100gに対し、1g以上溶解する樹脂を指す。
本実施形態において、水溶性樹脂(B)は、重量平均分子量2×105以上、1.5×106以下の高分子量水溶性樹脂(B-1)を含む。このような高分子量水溶性樹脂(B-1)を用いることにより、樹脂組成物の層のシート形成性がより向上し、より強度の強い樹脂組成物の層が形成でき、また樹脂組成物の層の厚さを均一にすることができ、さらに樹脂組成物の層の表面と金属箔面との密着性が高くなるので、結果として、ドリル孔あけ加工の際の孔位置精度がより向上し、また金属箔と樹脂組成物の層との間の接着力が強くなる。
また、水溶性樹脂(B)は、重量平均分子量1×103以上、7×103以下の低分子量水溶性樹脂(B-2)をさらに含むことが好ましい。このような低分子量水溶性樹脂(B-2)を用いることにより、エントリーシートの潤滑材としての効果がより向上し、ドリル孔あけ加工の際の孔位置精度がより向上する傾向にある。
樹脂組成物の層は、必要に応じて、添加剤を含有してもよい。添加剤の種類は、特に限定されないが、例えば、表面調整剤、レベリング剤、帯電防止剤、乳化剤、消泡剤、ワックス添加剤、カップリング剤、レオロジーコントロール剤、防腐剤、防黴剤、酸化防止剤、光安定剤、ギ酸Naなどの核剤、黒鉛などの固体潤滑剤、有機フィラー、無機フィラー、熱安定化剤、および着色剤が挙げられる。
樹脂組成物の層の厚さは、ドリル孔あけ加工する際に使用するドリルビット径や、加工する孔あけ対象物(例えば、積層板または多層板などのプリント配線板材料)の構成などによって適宜選択することができる。このような樹脂組成物の層の厚さとしては、特に限定されないが、好ましくは0.02~0.3mmであり、より好ましくは0.02~0.2mmである。樹脂組成物の層の厚さが0.02mm以上であることにより、より十分な潤滑効果が得られ、ドリルビットへの負荷が軽減されるので、ドリルビットの折損をさらに抑制することができる傾向にある。また、樹脂組成物の層の厚さが0.3mm以下であることにより、ドリルビットへの樹脂組成物の巻き付きを抑制することができる傾向にある。
本実施形態のドリル孔あけ用エントリーシートの製造方法は特に限定されるものではなく、金属箔上に樹脂組成物の層を形成する方法であれば一般的な製造方法が使用できる。
本実施形態のドリル孔あけ用エントリーシートは、積層板又は多層板のドリル孔あけ加工に用いられると、本実施形態の目的をより有効かつ確実に奏するので好ましい。なお、積層板としては、一般に「銅張積層板」が使用されることが多いが、本実施形態の積層板は「外層に銅箔のない積層板」であってもよい。本実施形態では特に明記しない限り、積層板は「銅張積層板」及び/又は「外層に銅箔のない積層板」の事を指す。また、そのドリル孔あけ加工は、直径(ドリルビット径)0.30mmφ以下のドリルビットによるドリル孔あけ加工であると、本実施形態の目的を更に有効かつ確実に奏することができる。特に、直径0.05mmφ以上0.30mmφ以下、さらには孔位置精度が重要になる直径0.05mmφ以上0.20mmφ以下の小径のドリルビット用途であると、孔位置精度およびドリル寿命を大きく向上させる点で好適である。なお、0.05mmφのドリルビット径は、入手可能なドリルビット径の下限であり、これよりも小径のドリルビットが入手可能になれば、上記の限りではない。また、直径0.30mmφ超のドリルビットを用いるドリル孔あけ加工に、本実施形態のドリル孔あけ用エントリーシートを採用しても問題ない。
本実施形態のドリル孔あけ加工方法は、上記ドリル孔あけ用エントリーシートを用いて、積層板又は多層板に孔を形成する工程を有する。その際、図1のように、ドリル孔あけ用エントリーシートの樹脂組成物の層側からドリルを侵入させてもよいし、金属箔側からドリルを侵入させてもよい。
接着力は、次のようにして測定した。まず、実施例及び比較例で作製したドリル孔あけ用エントリーシートを3mm幅、100mmの長さに切った試料を3点用意した。次に、試料の樹脂組成物の層の表面の全体に両面テープを貼り付けた。その後、両面テープを貼り付けた試料の片端を10mmはがし、はがした試料の金属箔部分にバネ秤を取り付けるための治具を取り付けた。治具にバネ秤(SANKO製、最大計測可能値1000gf)を取り付け、1cm/秒の速さで引っ張り、バネ秤の指す数値を読み取った。測定を3点の試料について行い、3回の平均値を接着力の数値とした。金属箔と樹脂組成物の層とが剥がれなかった場合は「>1000」と表記した。
○:200gf以上
×:200gf未満
孔位置精度は、次のようにして測定した。積み重ねた銅張積層板上に、実施例及び比較例で作製したドリル孔あけ用エントリーシートをその樹脂組成物の層を上にして配置し、所定回数のドリル孔あけ加工を行った。所定回数の孔全てにつき、積み重ねた銅張積層板の最下板の裏面(下面)における孔位置と指定座標とのズレを、ホールアナライザー(型番:HA-1AM、日立ビアメカニクス株式会社製)を用いて測定した。ドリルビット1本分ごとに、そのズレについて、平均値及び標準偏差(σ)を計算し、「平均値+3σ」を算出した。その後、ドリル孔あけ加工全体の孔位置精度として、使用したn本のドリルビットについてそれぞれの「平均値+3σ」の値に対する平均値を算出した。孔位置精度の算出に用いた式は、下記のとおりである。
○:18μm以下
×:18μmを超える
