Abstract
本發明提供一種熱固性樹脂組合物、由其製作之半固化片、覆金屬箔層壓板及高頻電路板,前述熱固性樹脂組合物包含熱固性成分,前述熱固性成分包含含磷單體或含磷樹脂以及含有不飽和基團之聚苯醚樹脂,前述含磷單體或含磷樹脂具有如式I所示之結構,利用含磷單體或含磷樹脂作為含有不飽和基團之聚苯醚樹脂的交聯劑,藉由樹脂中大量的不飽和雙鍵進行交聯反應來提供電路基板所需要的高頻介電性能及耐高溫性能。
Description
本發明屬於覆銅板技術領域,關於一種熱固性樹脂組合物、由其製作之半固化片、覆金屬箔層壓板及高頻電路板。
近年來,隨著訊息通訊設備高性能化、高功能化以及網路化的發展,為了傳輸及處理大容量訊息,操作訊號趨向於高頻化,因而對電路基板的材料提出了要求。
現有之用於印刷電路基板的材料中,廣泛使用黏接特性優異的環氧樹脂,然而,環氧樹脂電路基板一般介電常數及介質損耗角正切較高(介電常數大於4,介質損耗角正切0.02左右),高頻特性不充分,無法適應訊號高頻化之要求。因此必須研製介電特性優異之樹脂,即介電常數及介質損耗角正切低之樹脂。
另一類作為基板材料之熱塑性氟類樹脂(聚四氟乙烯),雖然介電常數及介質損耗角正切較低,但是氟類樹脂一般熔融溫度及熔融黏度高,因其流動性能差,成型難度大。且在製作多層電路板時,有加工性、尺寸穩定性及金屬鍍膜的黏結性不足等問題。
於是代替氟類樹脂,研究適合高頻高速用途之印刷電路板用的樹脂材料。其中,耐熱性聚合物中以介電特性優良的聚苯醚樹脂之使用受到注目。但是聚苯醚同樣為熔融溫度及熔融黏度高之熱塑性樹脂,因此等問題的存在,亦在應用中有很多挑戰,如滿足電子元件所需之低介質損耗角正切之同時難以達成所有電性能、阻燃性及機械性能(例如耐熱性、耐化學性、低吸濕性等)。另外在製造過程中可加工性差,會造成報廢率增大、可靠性變差。
為獲得滿足現代電子訊息技術發展需要的電路板,所屬技術領域之通常知識者進行大量的研究工作,以期望在各種性能、可靠性、製造加工性等各方面達到最佳,但效果均不理想。
另外,電子電器設備中使用之印刷電路基板材料,要求達到阻燃等級94V-0級,這對高頻高速電路板材料亦不例外。目前高頻高速電路板普遍採用以溴為主的含鹵類材料做阻燃劑。雖然含鹵類材料阻燃效果較佳,但有研究表明,含鹵類材料在燃燒時易釋放刺激性及有毒性的氣體,如鹵化氫、戴奧辛等,使人體健康受到危害。在一些電子產品中,已有禁止使用含鹵類的電路板材料。近年來,隨著人們環保觀念提高,電子電器中使用之電子材料趨向於無鹵化,皆在尋求可以替代鹵素類阻燃劑之其他類型阻燃劑以滿足阻燃的要求。金屬氫氧化物阻燃劑雖然不存在含鹵阻燃劑如此之毒性問題,但因其阻燃效率差,必須添加更大的量來獲得良好的阻燃性能,如此會導致樹脂混合、成型時的流動性差,使複合材料的加工及機械性能變差;另外由於金屬氫氧化物之介電常數大,用其作阻燃劑會帶來高頻電路基板介電性能之下降。含磷阻燃劑大都具有低煙、無毒之特
點,不僅具有良好的阻燃性能,並且能夠抑制煙霧及有毒氣體的釋放,符合添加量少、阻燃效果明顯的應用要求。
CN 103709718A公開一種無鹵高頻電路板基材之製作方法,其採用聚苯醚做主樹脂,烷基封端之二烯丙基雙酚A做固化劑,並採用添加型之含溴或含磷阻燃劑。其中採用添加型之含磷阻燃劑作為阻燃材料進行高頻覆銅板的製作,但所揭示的幾種含磷阻燃劑無反應基團,不參與複合材料樹脂分子間之交聯,由於此等含磷阻燃劑的熔點很低(小於200℃),用其製作之高頻電路基板材料的耐熱性差,無法滿足後續電路板元件裝配過程高溫焊接可靠性的要求。
CN106543228A公開具有下述結構的樹脂:
或,然而若將此種樹脂應用於覆銅板之製備,則由於其結構中含有羥基極性基團會使得製備得到的覆銅板之介電性能無法滿足要求。
CN106366128公開一種具有下述結構之膦菲類化合物:
,然而若將該化合物用於覆銅板之製備,則會由於其結構中存在的烯丙基醚結構而在加工過程中發生重排反應,導致產生二次羥基極性基團,同樣會使得製備得到的覆銅板之介電性能無法滿足要求。
因此,在本領域其中,期望開發一種既能夠保證具有良好的阻燃性能,又能夠在介電性能、耐熱性能等多個方面取得良好效果的熱固性樹脂組合物。
針對先前技術的不足,本發明之目的係提供一種熱固性樹脂組合物、由其製作之半固化片、覆金屬箔層壓板及高頻電路板,本發明之熱固性樹脂組合物不含有極性基團(例如羥基)、分子極性低、反應活性高,降低其固化物之介電常數及損耗,並且能夠保證固化物具有良好的阻燃性能、良好的機械強度以及良好的耐高溫等性能。

於本發明所記載之熱固性樹脂組合物中,前述含磷單體或含磷樹脂具有低極性之特徵,前述低極性係指不含有極性基團,尤其係不含有羥基基團,使得樹脂具有較低的極性,克服通用熱固性樹脂極性大導致的高頻介電常數及損耗高之缺陷,同時可藉由該結構中的烯丙基結構實現交聯固化,保證固化後之力學強度,並使得固化物具有優良的耐熱性能,同時,該樹脂中含有阻燃性含磷結構,使其具有優良的本徵阻燃效果。
於本發明中,前述含磷單體或含磷樹脂能夠適宜地與含有不飽和基團之聚苯醚樹脂進行配合,一同提升樹脂組合物之耐高溫以及耐濕熱性能,在具備較佳阻燃性之同時,使得由該樹脂組合物製備得到的固化物具有良好的耐熱性以及介電性能。
