Abstract: Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a Kurtosis (Rku) of the first surface ranges from 3.0 to 60.0. With the Rku, the LCP film is able to improve the peel strength with a metal foil and ensure that a laminate comprising the same maintains the merit of low insertion loss.

Abstract: Provided are an LCP film and a laminate comprising the same. The LCP film is made of an LCP resin comprising a structural unit represented by Formula (1): -L1-Ar-L2- (1), wherein -L1- and -L2- are respectively —O— or —CO—; —Ar— is an arylene group. Formula (1) comprises structural units




Based on a total molar number of the structural unit represented by Formula (1), a molar number of the structural unit represented by Formula (I) is in the range from 15 mole % to mole %, and a sum of molar numbers of the structural units represented by Formulae (I) and (II) is in the range from 80 mole % to 100 mole %. The LCP film has a thickness and a transmittance, wherein when values of the thickness (in μm) and the transmittance are put into Formula (III), the obtained value is from 0.055 to 0.090. Formula (III): Log(1/TT %)/(Thickness)0.5.

Abstract: Provided are a liquid crystal polymer film (LCP film) and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and the first surface has an arithmetical mean height of a surface (Sa) less than 0.32 μm. The LCP film with proper Sa is suitable to be stacked with a metal foil, such that a laminate comprising the LCP film can have an advantage of low insertion loss.

Abstract: Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a ratio of a ten-point mean roughness relative to a maximum height (Rz/Ry) of the first surface is from 0.30 to 0.62. By controlling Rz/Ry of at least one surface of the LCP film, the peel strength of the LCP film stacked to a metal foil can be increased, and the laminate comprising the same can still maintain the merit of low insertion loss.

Abstract: Provided are a laminate, a circuit board, and a liquid crystal polymer (LCP) film comprised therein. The laminate comprises a metal foil and an LCP film. The LCP film in the laminate has a dissipation factor before water absorption (Df′0), a dissipation factor after water absorption (Df′1), and a relative percentage difference between dissipation factors (ΔDf′), which is calculated by the following equation:

wherein ΔDf′ may be less than or equal to 16%.

By controlling ΔDf′ of the LCP film in the laminate, the insertion loss of a circuit board comprising a laminate during signal transmission in low-, medium-, and/or high-frequency bands is decreased and/or inhibited. In addition, the difference between the insertion losses of signal transmission before and after water absorption is decreased, so the laminate is suitable for high-end or outdoor high-frequency electronic products.
