Description

成形體、覆金屬積層體、印刷配線板及其等之製造方法
本發明涉及一種含有四氟乙烯系聚合物之成形體、覆金屬積層體、印刷配線板及其等之製造方法。
發明背景 針對用來傳輸高頻訊號的印刷配線板係講求傳輸遲延及傳輸損失小。為了提高傳輸特性,作為印刷配線板之電絕緣體層的絕緣材料,必須使用相對介電常數及介電正切小的材料。相對介電常數及介電正切小的材料以四氟乙烯系聚合物廣為周知。 專利文獻1、2中揭示了一種積層有導體與四氟乙烯系聚合物之薄膜的印刷配線板用積層體。 印刷配線板多半是於電絕緣體層兩側設有導體之積層體形成貫通孔後,於貫通孔之內壁面形成鍍層,以確保導體間之導通。於打孔加工,以往慣於使用數控鑽孔(NC drilling)、二氧化碳雷射之照射等。然而,近年隨著印刷配線板之配線規則微細化,孔之大小業已小徑化,故而有使用UV-YAG雷射之趨勢。 四氟乙烯系聚合物之UV波長區的吸收率很低。因此,具有四氟乙烯系聚合物之層的印刷配線板以UV-YAG雷射進行打孔加工時,必須照射高功率之雷射。高功率之雷射會在加工時產生熱使前述層或導體變形,而容易產生層間剝離等,因此很難開鑿適合用於形成鍍層的貫通孔。 專利文獻3中揭示了一種方法,係使四氟乙烯系聚合物之薄膜含有UV吸收劑以提升前述薄膜之UV吸收率,從而提升利用UV-YAG雷射的打孔加工性。但,若使用UV吸收劑,會降低四氟乙烯系聚合物之電絕緣等電特性。

TFE系聚合物可為含有以不具氟原子之單體(以下亦表記為「單體H」)為主體之單元(以下亦表記為「單元H」)的聚合物,亦可為不含單元H之聚合物。 單元H比起以含氟單體為主體之單元,在加熱時更容易碳化,而更容易調整成形體之吸光係數(α或β)。TFE系聚合物宜為含有單元H之聚合物。單元H可為1種亦可為2種以上。 單元H可舉:以不含具前述官能基之氟原子之單體H(以下亦表記為「官能單體H」)為主體的單元(以下亦表記為「官能單元H」)、以烯烴(乙烯等)為主體之單元、以乙烯基酯(乙酸乙烯酯等)為主體之單元。 若從加熱時容易碳化、而容易調整成形體之吸光係數(α或β)的觀點及能展現與其他基材之接著性的觀點來看,單元H宜為官能單元H。 若從容易調整成形體之吸光係數(α或β)的觀點及能展現與其他基材之接著性的觀點來看,官能單體H具有之官能基宜為含羰基之基團。含羰基之基團可舉酮基、碳酸酯基、羧基、鹵代甲醯基、烷氧羰基、酸酐基。另,「酸酐基」意指以-C(=O)-O-C(=O)-表示之基。 酮基宜含在碳數2~8之伸烷基中之碳原子間。另,前述伸烷基之碳數係不含酮基之碳原子之碳數。 鹵代甲醯基可舉-C(=O)F、-C(=O)Cl、-C(=O)Br、-C(=O)I,且以-C(=O)F為佳。 烷氧羰基中之烷氧基宜為碳數1~8之烷氧基,且甲氧基及乙氧基尤佳。 含羰基之基團宜為酸酐基及羧基。 官能單體H可舉馬來酸、伊康酸、檸康酸、十一碳烯酸等具羧基之單體、伊康酸酐(以下亦表記為「IAH」)、檸康酸酐(以下亦表記為「CAH」)、5-降莰烯-2,3-二羧酸酐(以下亦表記為「NAH」)、馬來酸酐等具酸酐基之單體、羥烷基乙烯基醚、環氧烷基乙烯基醚,且以具羧基之單體及具酸酐基之單體為佳。 具酸酐基之單體宜為IAH、CAH及NAH。 官能基單體可單獨使用1種,亦可將2種以上併用。
含有以官能單體H為主體之單元的TFE系聚合物,可舉含有TFE單元、官能單元H與以TFE以外之含氟單體為主體之單元的TFE系聚合物。 前述TFE系聚合物可舉:TFE、NAH與PPVE之共聚物;TFE、IAH與PPVE之共聚物;TFE、CAH與PPVE之共聚物;TFE、IAH與HFP之共聚物;TFE、CAH與HFP之共聚物;TFE、IAH、PFBE與乙烯之共聚物;TFE、CAH、PFBE與乙烯之共聚物;TFE、IAH、PFEE與乙烯之共聚物;TFE、CAH、PFEE與乙烯之共聚物;TFE、IAH、HFP、PFBE與乙烯之共聚物。 另,含有以具酸酐基之單體為主體之單元的TFE系聚合物中,有時會含有具有酸酐基之一部分經水解所形成之1,2-二羧酸基的單元。 TFE系聚合物中之官能單元H的比率宜相對於總單元為1.0莫耳%以下,0.5莫耳%以下較佳,0.3莫耳%以下更佳。單元H之比率可藉由核磁共振分析、紅外線吸收光譜分析等方法來測定。譬如,可利用日本專利特開第2007-314720號公報中記載之方法。
成形體之形狀可為薄膜狀(自支撐膜),亦可在其他基材上形成為層狀或塗膜狀。 含成形體之物品可舉:薄膜(單膜);具有成形體之層與導體金屬層的覆金屬積層體;在前述覆金屬積層體之前述層之厚度方向上形成貫通孔,藉以製得之具有成形體之層與導體金屬層且在前述層之厚度方向上具有貫通孔的印刷配線板。 薄膜厚度宜為1~50μm,2~25μm較佳。在此情況下,即容易製造傳輸損失小的印刷配線板,且可提升利用UV-YAG雷射進行之薄膜的打孔加工性。
本發明之製造方法係在氧濃度低於10000ppm之氣體環境下,將含有TFE系聚合物且TFE系聚合物以外之成分含量為0.9質量%以下的材料(以下亦表記為「前驅物材料」)加熱成形以製造成形體(本發明之成形體)之方法,該成形體之TFE系聚合物以外之成分含量為0.9質量%以下,且其所具吸光係數為1.2~4.5之波長區係於200~380nm。 TFE系聚合物通常其所具吸光係數為1.2~4.5之波長區不在200~380nm。本發明人等發現,將該TFE系聚合物在氧濃度低於預定範圍之氣體環境下進行加熱,即使不添加添加劑(前述之其他成分,以下皆同),也能獲得其所具吸光係數為1.2~4.5之波長區在200~380nm的TFE系聚合物。 前驅物材料可僅由TFE系聚合物構成,亦可含有TFE系聚合物與TFE系聚合物以外之其他成分,且宜僅由TFE系聚合物構成。此時,不僅成形體之電特性較佳,成形體對其他基材之接著性等也較佳。 前驅物材料僅由TFE系聚合物構成,意指未摻合TFE系聚合物以外之成分作為構成前驅物材料之成分,通常這代表前驅物材料中之添加劑含量為0質量%。另,前驅物材料為構成成形體之成分,而不會殘留在成形體中之成分並不含在前驅物材料之成分內。不會殘留在成形體中之成分可舉:在成形體製造過程中氣化散逸之液態介質,或是在成形體製造過程中分解而氣化散逸之熱分解性界面活性劑。另,液態介質意指水等分散媒或溶劑。 前驅物材料中之添加劑含量相對於前驅物材料之總質量為0.9質量%以下,宜為0.5質量%以下,0.3質量%以下較佳。
將前驅物材料加熱時之形態,可為熔融捏合形態,亦可為利用塗敷形成之層(塗膜)的形態。 加熱成形溫度宜為(Tm-15)~(Tm+100)℃,Tm~(Tm+80)℃較佳。前述溫度若在前述範圍之下限值以上,便容易將成形體之吸光係數(尤其是α或β)控制在期望範圍內。前述溫度若在前述範圍之上限值以下,便容易抑制吸光係數增大與成形體之電特性降低的情況。 加熱成形時間宜為10分鐘~48小時,10分鐘~24小時較佳。 加熱源可舉熱風、紅外線、經加熱之金屬。 若從經由加熱而產生之TFE系聚合物中之自由基與氧的反應來抑制TFE系聚合物之主鏈斷裂的觀點來看,加熱成形之氣體環境下的氧濃度低於10000ppm,且宜為5000ppm以下,1000ppm以下尤佳。前述氧濃度之下限通常為1ppm。 具體的氣體環境可舉在氧濃度低於10000ppm之非活性氣體(氮氣等)環境下之大氣壓條件下,或是在相當於氧濃度低於10000ppm之減壓氣體環境下(低於44kPa)。
根據本發明之製造方法,可獲得具有期望的吸光係數(尤其是α或β)之成形體的理由雖尚不十分明確,但吾等推想如下。 吾等以為,TFE系聚合物至少一部分會因成形之加熱而熱分解或改質,此時,氧濃度若被控制在預定範圍內,則會優先進行TFE系聚合物之碳化而促使碳生成,於是生成之碳會高度分散在成形體中。其結果,藉由碳之光吸收性,不僅可獲得具有期望的吸光係數之成形體,其雷射加工性也能獲提升。 亦即,吾等認為,相較於將以碳黑為代表之碳添加至TFE系聚合物中之情況,因碳更能高度分散,故可無損TFE系聚合物之物性,製得具有期望的吸光係數且適合利用UV-YAG雷射光進行加工的成形體。又,若氧濃度未被控制在預定範圍內,在TFE系聚合物之加熱時,則會優先進行TFE系聚合物之脫羧反應,促使二氧化碳生成,故而無法提升成形體之物性。 而此現象於TFE系聚合物具有容易引發熱分解之官能基(前述之官能基,尤指含羰基之基)時,對波長355nm或波長266nm之光尤為顯著。其結果,可製得具有期望的α或β並且適合利用UV-YAG雷射光進行加工的成形體。
本發明之製造方法可舉在氧濃度低於10000ppm之氣體環境下將前驅物材料進行加熱以熔融成形成薄膜狀而獲得薄膜(自支撐膜)之方法。 熔融成形之方法可舉擠製成形、充氣成形,利用擠製成形或充氣成形時使用之模具將TFE系聚合物加熱,可於成形時將前驅物材料加熱而獲得薄膜。 熔融成形之加熱溫度宜為(Tm+60)~(Tm+100)℃,(Tm+70)~(Tm+80)℃較佳。 又,亦可在氧濃度低於10000ppm之氣體環境下,將含有TFE系聚合物且TFE系聚合物以外之成分含量為0.9質量%以下的薄膜加熱成形,而獲得至少具有在波長200~380nm下吸光係數為1.2~4.5之區域的薄膜。 製造加熱前之薄膜的方法可舉在不會使吸光係數成為1.2以上之溫度下將前驅物材料熔融成形成薄膜狀的方法。 獲得加熱前之薄膜時的溫度宜為Tm~(Tm+50)℃,Tm~(Tm+30)℃較佳。 加熱前之薄膜的加熱裝置可舉烘箱、加熱爐。 加熱前之薄膜進行加熱時的溫度宜為(Tm-15)~(Tm+100)℃,Tm~(Tm+80)℃較佳。 加熱前之薄膜的加熱時間宜為10分鐘~48小時,10分鐘~24小時較佳。
根據本發明,將本發明之成形體(薄膜等)與導體金屬箔加熱壓附,可製造具有前述成形體之層與導體金屬層的覆金屬積層體。 本發明之製造方法亦可舉將使前驅物材料分散至液態介質中所得分散液塗敷成薄膜狀,並在氧濃度低於10000ppm之氣體環境下將之加熱而獲得薄膜的方法。 加熱溫度宜為Tm~(Tm+100)℃,Tm~(Tm+80)℃較佳。 液態介質可舉甲基乙基酮、N-甲基-2-吡咯啶酮等有機溶劑、水。液態介質可單獨使用1種亦可將2種以上併用。 分散液之塗敷方法可舉凹版塗佈法、微凹版塗佈法、凹版平版法、刮刀塗佈法、接觸塗佈法、棒塗法、模塗法、噴泉式繞線棒(fountain meyer bar)法、狹縫式模塗法。
根據本發明,藉由將包含前驅物材料及液態介質的液態組成物塗佈於導體金屬箔表面,然後去除液態介質,在此同時,在氧濃度低於10000ppm之氣體環境下進行加熱,使TFE系聚合物熔附於前述導體金屬箔上,可製造具有本發明之成形體之層(以下亦表記為「成形層」)與導體金屬層的覆金屬積層體。 且可連續進行從藉由塗佈液態組成物而形成之液態組成物之膜並利用加熱等去除液態介質而形成TFE系聚合物之層的步驟,以及將TFE系聚合物之層熔附於導體金屬箔上的步驟。即,可在加熱下連續進行從液態組成物之膜去除液態介質與TFE系聚合物之層的熔附。
覆金屬積層體亦可含有導體金屬層及成形層以外之其他層。其他層可舉耐熱性樹脂層。 覆金屬積層體之層構成可舉:導體金屬層/成形層/耐熱性樹脂層、導體金屬層/成形層/耐熱性樹脂層/成形層/導體金屬層、導體金屬層/耐熱性樹脂層/成形層/耐熱性樹脂層/導體金屬層。 導體金屬層可舉金屬箔、金屬薄膜、金屬片材等,且以銅箔為佳。銅箔可舉軋延銅箔、電解銅箔。銅箔亦可形成有其他層,具體來說,亦可形成有鉻酸鋅等防鏽層或鎳、鈷等障壁層。又,障壁層可藉由鍍覆處理形成,亦可藉由化學轉化處理形成。 為了提升導體金屬層與成形層之密著性,導體金屬層之表面亦可業經矽烷耦合劑處理。矽烷耦合劑可舉環氧矽烷、胺基矽烷、乙烯基矽烷、丙烯醯氧基矽烷、甲基丙烯醯氧基矽烷、脲基矽烷、巰基矽烷、硫基矽烷、異氰酸酯矽烷,且以丙烯醯氧基矽烷、甲基丙烯醯氧基矽烷、環氧矽烷為宜。矽烷耦合劑可使用1種,亦可將2種以上組合使用。 導體金屬層亦可以無電電鍍、濺鍍、電鍍與濺鍍之組合來形成。 導體金屬層之可配置成形層之側的表面的RzJIS 宜為0.3~1.6。RzJIS 只要為0.3以上,利用UV-YAG雷射進行打孔加工時,就不易在導體金屬層與成形層之間引起層間剝離。RzJIS 只要在1.6以下,便可抑制傳輸損失因粗度而大增。 導體金屬層之厚度宜為3~18μm以下,6~12μm以下較佳。
成形層之介電正切宜為0.0005~0.0020,0.0007~0.0015較佳。介電正切愈低,成形層之電特性愈優異。 成形層厚度宜為1~50μm,2~25μm較佳。成形層厚度只要在前述範圍之下限值以上,便容易獲得傳輸損失小的印刷配線板。TFE層厚度只要在前述範圍之上限值以下,便能提升UV-YAG雷射的加工性。成形層具有多層時,各層厚度宜設定在前述範圍內。
形成耐熱性樹脂層之材料可舉聚醯亞胺、液晶聚合物、聚醚醚酮、聚伸苯醚、聚酯、聚醯胺、芳醯胺纖維。其中,又宜選自於由聚醯亞胺、液晶聚合物、聚醚醚酮、聚伸苯醚及芳醯胺纖維所構成群組中之至少1種,且聚醯亞胺或液晶聚合物較佳。 耐熱性樹脂宜為聚醯亞胺薄膜、液晶聚合物薄膜。 聚醯亞胺薄膜可舉非熱可塑性芳香族聚醯亞胺薄膜、經於非熱可塑性芳香族聚醯亞胺薄膜塗敷熱可塑性聚醯亞胺所形成之薄膜。 耐熱性樹脂層在利用雷射進行之打孔加工性的觀點下,以不同種材料較少者為宜,且宜為單層之非熱可塑性芳香族聚醯亞胺薄膜。 覆金屬積層體具有耐熱性樹脂層時,成形層之合計厚度相對於耐熱性樹脂層之合計厚度之比宜為0.5~2。前述比只要在前述範圍之下限值以上,便能輕易利用雷射進行打孔加工。前述比只要在前述範圍之上限值以下,就可輕易降低傳輸損失。
覆金屬積層體厚度宜為10~150μm,15~100μm較佳,20~50μm更佳。積層體厚度只要在前述範圍之下限值以上,作為印刷配線板更能穩定使用。積層體厚度只要在前述範圍之上限值以下,便可輕易利用UV-YAG雷射形成貫通孔。
本發明之印刷配線板具有成形層與導體金屬層,並於成形層之厚度方向上具有貫通孔。 形成在印刷配線板上之貫通孔的開口形狀可舉圓形。 開口形狀為圓形時,貫通孔的大小譬如可將直徑設定在0.05~0.10mm之範圍內。 貫通孔數可為1個亦可為2個以上。 貫通孔之內壁面亦可視需求形成鍍層。譬如,當印刷配線板於厚度方向兩側分別具有導體時,於貫通孔之內壁面形成鍍層即可確保導體彼此間之導通。 鍍層可舉鍍銅層、鍍金層、鍍鎳層、鍍鉻層、鍍鋅層、鍍錫層。 傳輸損失係表示印刷配線板之信號從輸入部至輸出部之信號衰減的參數。 印刷配線板之傳輸損失在40GHz下宜為-0.07dB/mm以上,-0.06dB/mm以上較佳。
印刷配線板之製造方法可舉:對本發明之覆金屬積層體照射UV-YAG雷射進行打孔加工而形成貫通孔之方法。 UV-YAG雷射之波長宜為3次諧波(波長355nm)或4次諧波(266nm)。 於打孔加工可使用UV-YAG雷射加工機。利用UV-YAG雷射進行之打孔加工可採用環鋸(trepanning)加工。具體上,可使已限縮徑長之雷射沿著欲打出貫通孔之部分的周緣環繞並進行照射,而將覆金屬積層體局部打穿,形成貫通孔。 雷射之功率、照射雷射並環繞之次數、雷射之振盪頻率可因應積層體厚度來設定,通常為0.01~3.0W。 使用波長355nm之雷射光時,雷射的功率宜為0.1~3.0W,且0.5~2.0W較佳。使用波長266nm之雷射光時,雷射的功率宜為0.01~0.5W,且0.05~0.3W較佳。雷射的功率只要在前述範圍之下限值以上,便能輕易形成貫通孔。雷射的功率只要在前述範圍之上限值以下,便可減少雷射之熱所造成的樹脂飛散物。 雷射照射之環繞次數宜為5~50次。 使用波長355nm之雷射光時,雷射的振盪頻率宜為20~80kHz。使用波長266nm之雷射光時,雷射的振盪頻率宜為1~10kHz。
在本發明中,印刷配線板之成形層的吸光係數係利用加熱而控制在預定範圍內。藉此,即使不用添加劑,也能提高UV-YAG雷射之吸收率,因此可抑制電特性降低的情況,同時可用UV-YAG雷射輕易地形成小口徑的貫通孔。 本發明之印刷配線板適合用在高頻用途。 實施例
