Description

可撓性半固化片及其應用
本發明係關於一種可撓性半固化片(prepreg),尤其係關於一種藉由將一液晶聚合物不織布含浸或塗佈一熱固化性樹脂組合物,並乾燥該經含浸或塗佈之液晶聚合物不織布而製得的可撓性半固化片,及使用該可撓性半固化片所提供之可撓性金屬箔積層板(laminate)及印刷電路板。
印刷電路板(printed circuit board,PCB)可作為電子裝置之基板,可搭載多種彼此可相互電性連通之電子構件,以提供安穩的電路工作環境。印刷電路板主要由積層板製得,積層板係由介電層與導電層交互層合而形成。一般而言,印刷電路板可由如下方法製備。
首先,將補強材(例如玻璃織物)含浸於樹脂(例如環氧樹脂)中,並將經含浸樹脂之補強材固化至半固化狀態(即B-階段(B-stage))以獲得作為介電層之半固化片。隨後,將預定層數之介電層(半固化片)層疊,並於所層疊介電層之至少一外側層疊一導電層(例如金屬箔)以提供一層疊物,接著對該層疊物進行一熱壓操作(即C-階段(C-stage))而得到一積層板。將該積層板表面的導電層加以蝕刻以形成預定的電路圖案(circuit pattern)。最後,在該經蝕刻之積層板上鑿出複數個孔洞,並在此等孔洞中鍍覆導電材料以形成通孔(via holes),即完成印刷電路板之製備。
隨著電子儀器的小型化,印刷電路板亦必須滿足薄型化、高密度化、及高頻高速傳輸的需求。對此,目前多數使用氟樹脂基板或聚苯醚樹脂基板來滿足高頻高速傳輸的需求。例如,JP 61-287939揭露一種積層板,其係藉由將含浸有樹脂之基材積層成形後照射放射線而製得,其中該含浸有樹脂之基材係使基材含浸於含有聚苯醚及交聯性聚合物之樹脂組合物中而形成。JP 8-245872揭露一種固化性複合材料,其中包含聚苯醚與不飽和羧酸或酸酐之反應產物、氰脲酸三烯丙酯及/或異氰脲酸三烯丙酯、過氧化物、阻燃劑、氧化銻及基材。然而,上述技術方案係使用玻璃纖維基材,所製材料不具可撓性。
US 2018270945亦揭露一種由絕緣層(即介電層)及導電層堆疊而成之多層印刷配線板,其中該絕緣層包括液晶聚合物樹脂層,該液晶聚合物樹脂層為由液晶聚合物樹脂所製成的薄膜。雖然如此可使得該多層印刷配線板具有可撓性,惟亦造成絕緣層與導電層之間的黏合性不佳,進而導致多層印刷配線板的可靠度下降。
有鑑於以上技術問題,本發明利用液晶聚合物不織布及熱固化性樹脂組合物提供一種半固化片,該半固化片具有可撓性,可依照空間改變形狀做成立體配線,因此可提升系統的配線密度及縮減產品體積。此外,使用本發明半固化片所製得之可撓性金屬箔積層板具有低介電常數(Dk)值、低介電耗損因子(Df)、高耐熱性、及導電層與介電層間的高黏合性等特點。
因此,本發明之一目的在於提供一種半固化片,其係藉由將一液晶聚合物不織布含浸或塗佈一熱固化性樹脂組合物,並乾燥該經含浸或塗佈之液晶聚合物不織布而製得,其中該熱固化性樹脂組合物包含: (A)一不飽和單體;以及(B)一環狀烯烴共聚物,該環狀烯烴共聚物係包含以下重複單元:(B-1)具有如下式(I)結構之重複單元,

茲以下列具體實施態樣進一步例示說明本發明,其中,所採用之量測儀器及方法分別如下:[介電常數(Dk)與介電耗損因子(Df)量測]
根據IPC-TM-6502.5.5.13規範,在工作頻率10吉赫(GHz)下,計算金屬箔積層板之介電常數(Dk)與介電耗損因子(Df)。
[剝離強度測試]
剝離強度係用於顯示金屬箔導電層與介電層間之附著力強弱。本測試中係以1/8英寸寬度的銅箔自板面上垂直撕起,以其所需力量的大小來表達附著力的強弱。剝離強度的單位為磅力/英寸(lbf/in)。
[可撓性測試]
可撓性測試係依照MIT測試方法(JIS P8815規範)紀錄其MIT撓曲次數。若MIT撓曲次數大於100次,則記錄為「○」;若MIT撓曲次數介於50至100次之間,則記錄為「△」;若MIT撓曲次數小於50次,則記錄為「×」。
[吸濕後耐熱性測試]
吸濕後耐熱性係依照JIS C5012之方法測試,係評估金屬箔積層板於60℃及相對溼度(RH)60%環境下120小時後焊料漂浮之耐熱性。將金屬箔積層板在288℃的焊浴中進行浮焊60秒後,利用目視及光學顯微鏡(x5倍以上),觀察浮焊測試後金屬箔積層板是否出現斑痕(measling)或膨脹等情形。若未觀察到斑痕或膨泡等之發生,則記錄為「○」;若觀察到彼等情形發生,則記錄為「×」。

6.3. 金屬箔積層板之製備
以表1及表2所示之比例配製實施例1至9及比較例1至6之熱固化性樹脂組合物,將各成分於室溫下使用攪拌器混合60分鐘,隨後再加入甲苯(實施例1至9以及比較例1至3及5及6)或MEK(比較例4)。將所得混合物於室溫下攪拌約60至120分鐘後,製得各該熱固化性樹脂組合物。
分別使用所製得之熱固化性樹脂組合物來製備實施例1至9及比較例1至6之半固化片。首先,經由輥式塗佈機,將液晶聚合物不織布或玻璃纖維布分別含浸實施例1至9及比較例2至6之熱固化性樹脂組合物;或者利用塗佈機塗佈比較例1之熱固化性樹脂組合物於液晶聚合物膜之上下二面,塗佈厚度為13微米。接著,將該等經含浸或塗佈之液晶聚合物不織布、玻璃纖維布及液晶聚合物膜置於160℃之乾燥機中加熱乾燥3分鐘,藉此製得半固化片。
分別使用所製得之半固化片來製備實施例1至9及比較例1至6之金屬箔積層板。將銅箔與半固化片接觸層疊,接著進行熱壓操作,分別製得實施例1至9與比較例1至6之金屬箔積層板。熱壓條件為:以3.0℃/分鐘之升溫速度升溫至200℃至220℃,並在該溫度下,以全壓15公斤/平方公分(初壓8公斤/平方公分)之壓力熱壓180分鐘。

Figure 108100372-A0101-12-0029-99
6.4. 金屬箔積層板之性質量測
依照前文所載量測方法測量實施例1至9及比較例1至6之金屬箔積層板之各項性質,包括介電常數(Dk)、介電耗損因子(Df)、可撓性、吸濕後耐熱性、及剝離強度,並將結果紀錄於表3及表4中。
表3:實施例之金屬箔積層板之性質
Figure 108100372-A0101-12-0030-100
Figure 108100372-A0101-12-0030-101
如表3所示,本發明半固化片所製得之金屬箔積層板除具有良好可撓性、低介電常數(Dk)值、低介電耗損因子(Df)及高耐熱性之外,更具有半固化片與銅箔間之剝離強度高的優點。
相較於此,如表4所示,採用非本發明半固化片所製得之金屬箔積層板並無法在所有物化性質及介電性質上均達到令人滿意的程度, 也無法具有良好的銅箔與半固化片之間的剝離強度。具體言之,如比較例1所示,當金屬箔積層板使用液晶聚合物膜時,其可撓性、剝離強度及耐熱性皆不佳。如比較例2所示,當金屬箔積層板使用NE-glass等級之玻璃纖維布時,其可撓性及介電常數皆不佳。如比較例3所示,當熱固化性樹脂組合物僅含環狀烯烴共聚物時,金屬箔積層板之耐熱性不足。如比較例4所示,相較於使用本發明熱固化性樹脂組合物,當使用其他熱固化性樹脂組合物時,金屬箔積層板之電性無法滿足需求。如比較例5所示,當熱固化性樹脂組合物中之環狀烯烴共聚物(B)對該不飽和單體(A)之重量比大於7時,金屬箔積層板之耐熱性不足。如比較例6所示,當熱固化性樹脂組合物中之環狀烯烴共聚物(B)對該不飽和單體(A)之重量比小於0.5時,金屬箔積層板之可撓性及剝離強度不佳。
上述實施例僅為例示性說明本發明之原理及其功效,並闡述本發明之技術特徵,而非用於限制本發明之保護範疇。任何熟悉本技術者在不違背本發明之技術原理及精神下,可輕易完成之改變或安排,均屬本發明所主張之範圍。因此,本發明之權利保護範圍係如後附申請專利範圍所列。
