Abstract
本創作關於一種液晶高分子膜及包含其之積層板。液晶高分子膜具有相對的第一表面和第二表面,該第一表面的十點平均粗糙度 (Rz)相對於最大高度 (Ry)的比值為0.30至0.62。藉由控制液晶高分子膜至少一表面的Rz/Ry能提升液晶高分子膜與金屬箔疊合的剝離強度,並使包含其之積層板仍維持低訊號損失的優點。
Description
本創作係關於一種應用於積層板的高分子膜,尤指一種液晶高分子膜及包含其之積層板。
隨著行動通訊技術的快速發展,業界正積極開發第五代行動通訊技術 (5th
Generation Mobile Networks,簡稱5G),以優化4G通訊技術的資料傳輸速度、回應時間、系統容量等效能。
由於5G通訊技術係利用高頻波段進行訊號傳輸,當訊號頻率越高時,傳遞的訊號損失 (insertion loss)也越大。為了符合在高頻波段達成訊號傳輸的目的,現有技術已知可選擇低介電性質的液晶高分子膜 (Liquid Crystal Polymer Film,簡稱LCP膜)搭配金屬箔製作積層板,以設法降低訊號傳輸的絕緣損失。
然而,液晶高分子膜與金屬箔之間多半存在附著性不足的問題,於後續使用上易導致線路脫落而嚴重劣化積層板的後續加工。因此,現有技術仍有待改善液晶高分子膜與金屬箔之間的剝離強度,以設法開發適用於5G產品的積層板。
有鑑於此,本創作之目的在於提升液晶高分子膜與金屬箔之間的剝離強度。
為達成前述目的,本創作提供一種液晶高分子膜,其具有相對的第一表面和第二表面,該第一表面的十點平均粗糙度 (ten-point mean roughness,Rz)相對於最大高度 (maximum height,Ry)的比值 (簡稱Rz/Ry)係0.30至0.62。
藉由控制液晶高分子膜其中一表面 (第一表面)的Rz/Ry之特性,能增加液晶高分子膜疊合在金屬箔上的附著性,提升液晶高分子膜與金屬箔之間的剝離強度,從而避免積層板於後續加工中發生如線路脫落之問題。
依據本創作,就液晶高分子膜的第二表面而言,其Rz/Ry也可為0.30至0.62;據此,本創作之液晶高分子膜不論是透過第一表面、第二表面或其二者分別與至少一金屬箔疊合皆能獲得良好的附著性,從而提升液晶高分子膜與至少一金屬箔之間的剝離強度。較佳的,本創作之液晶高分子膜的第一表面及/或第二表面的Rz/Ry也可為0.36至0.61。於其中一實施態樣中,本創作之液晶高分子膜之第一表面的Rz/Ry與第二表面的Rz/Ry可為相同或不同。於其中一實施態樣中,本創作之液晶高分子膜的第一表面的Rz/Ry及第二表面的Rz/Ry皆落在前述範圍。
依據本創作,液晶高分子膜的第一表面的Rz小於或等於2微米 (µm)。較佳的,本創作之液晶高分子膜的第一表面的Rz小於或等於1.5 µm;更佳的,本創作之液晶高分子膜的第一表面的Rz可大於或等於0.3 µm且小於或等於1.5 µm;再更佳的,本創作之液晶高分子膜的第一表面的Rz可大於或等於0.3 µm且小於或等於1.4 µm;又更佳的,本創作之液晶高分子膜的第一表面的Rz可大於或等於0.3 µm且小於或等於1.3 µm;再又更佳的,本創作之液晶高分子膜的第一表面的Rz可大於或等於0.35 µm且小於或等於1.2 µm;又再又更佳的,本創作之液晶高分子膜之第一表面的Rz可大於或等於0.39 µm且小於或等於1.2 µm。於其中一實施態樣中,本創作之液晶高分子膜之第一表面的Rz與第二表面的Rz可為相同或不同。於其中一實施態樣中,本創作之液晶高分子膜的第一表面的Rz及第二表面的Rz皆落在前述範圍。
依據本創作,液晶高分子膜的第一表面的Ry可小於或等於2.2 µm。於其中一實施態樣中,本創作之液晶高分子膜的第一表面的Ry可小於或等於2.0 µm;更佳的,本創作之液晶高分子膜的第一表面的Ry可大於或等於0.5 µm且小於或等於1.8 µm;再更佳的,本創作之液晶高分子膜的第一表面的Ry可大於或等於0.6 µm且小於或等於1.6 µm。於其中一實施態樣中,本創作之液晶高分子膜之第一表面的Ry與第二表面的Ry可為相同或不同。於其中一實施態樣中,本創作之液晶高分子膜的第一表面的Ry及第二表面的Ry皆落在前述範圍。
較佳的,本創作之液晶高分子膜的第一表面的算術平均粗糙度 (arithmetic average roughness,Ra)可小於或等於0.09 µm,據此,所述液晶高分子膜應用於積層板中能有利於降低其訊號損失,使其更加適用於高階的5G產品中。
更佳的,本創作之液晶高分子膜的第一表面的Ra可大於或等於0.02 µm且小於或等於0.08 µm;再更佳的,第一表面的Ra可大於或等於0.02 µm且小於或等於0.07 µm;又再更佳的,第一表面的Ra可大於或等於0.02 µm且小於或等於0.06 µm。藉由降低液晶高分子膜的第一表面的Ra之技術手段,能進一步降低包含液晶高分子膜之積層板的訊號損失,使其更加適用於高階的5G產品中。於其中一實施態樣中,本創作之液晶高分子膜之第一表面的Ra與第二表面的Ra可為相同或不同。於其中一實施態樣中,本創作之液晶高分子膜的第一表面的Ra及第二表面的Ra皆可落在前述範圍。

實驗結果討論
如上表2所示,實施例1至13之液晶高分子膜其中一表面的Rz/Ry皆控制在0.30至0.62,故此種液晶高分子膜與各種市售之低粗糙度銅箔壓合所形成的積層板 (實施例1A至13A)皆能展現高的剝離強度。又如上表3之結果,以實施例1A至7A之積層板的測試結果為例,當液晶高分子膜其中一表面的Rz/Ry控制在0.30至0.62,實施例1A至7A之積層板的訊號損失也能控制在-3.1 dB以下。
進一步探討表2所示結果,比較含有銅箔1之積層板的實驗結果,相較於比較例1至4之液晶高分子膜,實施例1至4之液晶高分子膜皆展現較高的剝離強度;同樣的,比較含有銅箔2之積層板的實驗結果,相較於比較例5之液晶高分子膜,實施例5至7之液晶高分子膜皆展現較高的剝離強度。清楚地,選用本創作之液晶高分子膜製備積層板,確實具有提升剝離強度的功效,故能有利於加工、有效避免後續發生如線路脫落的問題。
再者,由實施例1A至7A之積層板的測試結果可見,當液晶高分子膜其中一表面的Rz/Ry控制在0.30至0.62之範圍且其Ra亦控制在0.09 µm以下時,選用此種液晶高分子膜與銅箔壓合能夠在提升積層板 (實施例1A至3A及5A至7A)之剝離強度的前提下,進一步控制積層板的訊號損失在-2.9 dB以下,提供同時展現高剝離強度與低訊號損失的積層板。
綜上所述,本創作藉由控制液晶高分子膜至少一表面的Rz/Ry係0.30至0.62,能具體提升液晶高分子膜與金屬箔疊合的剝離強度。此外,合併控制液晶高分子膜至少一表面的Rz/Ry以及Ra之特性,不僅能提升積層板的剝離強度,更能進一步降低積層板的訊號損失,致使本創作之積層板更加適用於高階的5G產品中。
