Description
また、その上にレジストを塗布し、更にめっきを行って配線する際に、銅表面の光沢性が高かったため、レジスト剥離が生じる場合があり、レジストとの密着性に優れている2層フレキシブル基板が求められている。
即ち、本発明は、
(1)絶縁体フィルムの片面又は両面上に、予め下地金属層を形成し、その上に所定の厚さの銅層を電気めっきにより形成することにより、接着剤を用いることなく銅層を設けた2層フレキシブル基板であって、該絶縁体フィルム上に形成した銅層の結晶粒径が絶縁体フィルム面に近い程小さく、また銅層の表面粗さ(Ra)が0.10〜0.25μmで、かつ上記銅層断面の、該絶縁体フィルムから1μmの高さの部分の銅の平均結晶粒径が0.8μm以下であることを特徴とする2層フレキシブル基板、
(2)前記絶縁体フィルムがポリイミドフィルムであることを特徴とする前記(1)記載の2層フレキシブル基板、
である。
発明の効果
また、この表面粗さは、ファインライン形成に影響がなく、表面欠陥がなくなり、歩留まりが向上する。
絶縁体フィルムとしては、厚さ10〜50μmのフィルムが好ましい。
下地金属層の厚さは10〜500nmが好ましい。
このときめっき液としては、通常の酸性銅めっき液を使用することができ、硫酸銅水溶液に、塩素、ノニオン系界面活性剤、硫黄系有機化合物を添加剤として混合した水溶液を用いることが好ましく、膜厚3〜30μmの銅層を形成することが好ましい。

表面粗さを上記範囲(表面が適度に荒れている)とすることにより、ソルダーレジストとの密着性が良好となる。また、表面が光沢面であった場合、欠陥となる微小な突起やくぼみは、表面粗さを上記範囲とすることにより、粗さに紛れるので、表面の微小欠陥がなくなり、歩留まりが向上する。表面粗さ(Ra)が0.10〜0.25μmの範囲ではファインラインの対応が可能な表面粗さである。
本発明において、銅層の銅の結晶平均粒径は、上述のように絶縁体フィルム表面に近いほど小さくなる。したがって、絶縁体フィルムから1μmのところの銅の平均結晶粒径が0.8μm以下であると、1μmより絶縁体フィルムに近いところでは、それ以下となる。
絶縁体フィルムから1μmのところの銅の平均結晶粒径は、例えば、FIB切断した後、SIMで観察し、結晶の粒径の観察や測定することにより求めることができる。
実施例1〜2、比較例1〜3
以下のめっき条件で下地金属層を有するポリイミドフィルムに電気めっきを行い、約8μmの銅被膜を作製した。添加剤及びその添加量は表1記載の通りである。
液容量: 約800ml
アノード:鉛電極
カソード:ポリイミドフィルムを巻きつけた回転電極
下地金属層を有するポリイミドフィルム:
37.5μm厚のカプトンE(デュポン製)上にNiCrを10nm+Cuを2000Å
スパッタ成膜したもの。
電流時間:1300As
電流密度:5→10→20→30A/dm2と変化(各電流密度で40秒ずつ保持)
流速: 190r.p.m.
Cu: 70g/L
H2SO4:60g/L
Cl: 75ppm
平均結晶粒径は、FIBより断面を切断した後、SIMで観察し、ポリイミドから1μmの高さの部分(10μm幅)の結晶粒径の平均値を求めた。結果は表1に示す。
欠陥の個数は、銅層表面1dm2の欠陥数(微小な突起またはくぼみの数)を目視にて求めた。尚、結果は表1に示す。
エッチング特性は、エッチング率により評価した。エッチング率は、20μmピッチのラインを形成し、下記に示す計算式に基づき計算した。
エッチング率=h/{(b−t)/2}(=tanθ)
h、b、tは図1に示すように、h=エッチングの深さ、b=基板表面のエッチングの幅、t=エッチング底面のエッチングの幅を示す。
結果は表1に示す。
無電解金めっき耐性により評価した。実施例1〜2、及び比較例1〜2で得られた基板上に市販のソルダーレジストを塗布した。露光、現像後硬化し評価基板を作製した。この評価基板を市販の無電解Niめっき液と無電解金めっき液を用いてめっきを行った。このめっき後の評価基板について、セロテープ(登録商標)によるピールテストを行い、レジストの剥がれについて評価した。実施例1、2の基板を使用したものは、レジストに全く剥がれが認められなかったのに対し、比較例1、2の基板を使用したものは、かすかに剥がれが見られた。
