Definitions
- the present invention relates to a surface-treated copper foil for a copper clad laminate for producing a flexible printed wiring board (FPC) capable of efficiently transmitting a high-frequency electric signal.
- FPC flexible printed wiring board
- a flexible printed wiring board is manufactured by etching a copper foil of a substrate to form various wiring patterns, and connecting and mounting electronic components with solder.
- Copper foils are classified into electrolytic copper foils and rolled copper foils because of their production methods, and rolled copper foils having excellent bending resistance have been used favorably as copper foils for flexible substrates.
- electronic devices such as personal computers and mobile communications, with the increase in communication speed and capacity, the frequency of electrical signals is increasing, and printed wiring boards and copper foils that can cope with this are demanded. .
- the frequency of electrical signals is high, but when the frequency of electrical signals exceeds 1 GHz, the effect of the skin effect in which current flows only on the surface of the conductor becomes noticeable. The effect of changing the current transmission path and increasing the conductor loss cannot be ignored. Also from this point, it is desired that the surface roughness of the copper foil is small.
- the surface of the electrolytic copper foil of the raw foil is formed by electrodeposition of copper, and the surface of the rolled copper foil of the raw foil is formed by contact with a rolling roll. Therefore, generally the surface roughness of the rolled copper foil of raw foil is smaller than the surface roughness of the electrolytic copper foil.
- the electrodeposited particles in the roughening treatment are finer in the rolled copper foil. From this meaning, it can be said that the rolled copper foil is excellent as a copper foil for a high-frequency circuit.
- the conductor side tends to shift to a copper foil with a small surface roughness
- the resin side tends to shift from polyimide to liquid crystal polymer.
- the most desirable from the viewpoint of the skin effect is considered to be a copper foil with small roughness that does not form a roughening treatment.
- the loss (attenuation) of signal power in an electronic circuit can be roughly divided into two.
- One of them is a conductor loss, that is, a loss due to copper foil
- the second is a dielectric loss, that is, loss due to a substrate.
- the conductor loss there is a skin effect in a high frequency region, and current has a characteristic that the current flows on the surface of the conductor. For this reason, if the copper foil surface is rough, a current flows along a complicated path.
- the conductor loss tends to be small.
- a liquid crystal polymer is a polymer that exhibits optical anisotropy in a liquid phase (molten or solution), and needs to be laminated without an adhesive with a copper foil.
- the wholly aromatic polyester-based liquid crystal polymer is a halogen-free material that exhibits molecular orientation even in the molten state and maintains this state even in the solid state and exhibits thermoplasticity.
- liquid crystal polymer (LCP) has a low dielectric constant and a low dielectric loss tangent.
- the relative dielectric constant of LCP is 3.3
- the relative dielectric constant of polyimide is 3.5
- the dielectric loss tangent is 0.002 for LCP
- that of polyimide is 0.01. Therefore, the liquid crystal polymer (LCP) is superior in characteristics.
- the liquid crystal polymer (LCP) has a feature of low water absorption and low moisture absorption, and has a great advantage that there is little change in electrical characteristics and little change in dimensions.

- FPC flexible printed circuit board
- LCP liquid crystal polymer
- the present inventors have found that transmission loss can be reduced for the following reason.
- One of them is that it is greatly influenced by the surface of the copper foil in the high frequency region. As the surface roughness increases, transmission loss increases. Therefore, it is effective to adjust the surface roughness of the copper foil as small as possible.
- the second is the use of a liquid crystal polymer (LCP) laminated substrate.

Abstract
Description
しかしながら、液晶ポリマー(LCP)はポリイミドと比較して強度が弱く、銅箔を積層した材料はピール強度が出難いという大きな問題を有している。銅箔の粗さを大きくすると、物理的なアンカー効果が得られることからピール強度は高くなる傾向にあるが、前述の表皮効果の影響によって、高周波における電気特性が悪化してしまう。
また、高周波回路用銅箔の提案がいくつかあるが(例えば、特許文献2、3、4、5参照)、圧延銅箔の製造工程の簡素化と高周波伝送損失を減少させるという観点から、有効な技術がないのが現状である。
その一は、高周波領域において銅箔の表面に大きく影響されるということである。表面粗さが大きくなると伝送損失は大きくなる。したがって、銅箔の表面粗さを、できるだけ小さく調整することが有効である。
その二は、液晶ポリマー(LCP)積層基板の利用である。しかしこのためには、銅箔との接着強度(ピール強度)を高める必要がある。
以上の問題を解決することによって、信号電力損失(減衰)を抑制したフレキシブルプリント基板(FPC)を提供することができるという知見を得た。
