Description
技术领域
本发明涉及通信材料覆铜板领域技术,尤其是指一种树脂组合物及树脂胶液、预浸料、层压板、印刷线路板。
背景技术
目前电子行业发展迅猛,对覆铜板性能的要求越来越高,随着5G时代的到来和智能终端朝向小型化、薄型化,多功能化、高性能化的发展,对印刷线路板也提出了更高的要求:要求小型化、薄型化、高集成化和高可靠性。这就要求用于制作印刷线路板的覆铜板要具有更低的平面(XY)向热膨胀系数、低介电性能、更高的耐热性和更好的尺寸稳定性,因此近年来为了减少生产过程中产生的翘曲问题,锡球脱落问题,降低基材的平面(XY)方向热膨胀系数成为覆铜板行业研发的热点。
一般同时实现低XY轴热膨胀系数和低介电性能较难,普通FR4,XY轴热膨胀系数一般大于16ppm/℃,介电性能不足;碳氢体系,虽然实现了低介电性能,但由于碳氢树脂通常具有为长链烷烃结构,XY轴热膨胀系较大。PPO体系组合,虽然相比碳氢体系具有更多苯环骨架,通过高填料填充比例实现低XY轴CTE,但很难降到12ppm/℃。一般的BT封装基板,虽然容易实现低XY轴CTE,但介电性能较高,而且填胶性能差,板材加工性能下降,导致出现严重缩短钻刀的使用寿命等弊端,无法做多层板,更难实现板材的高密度互联,而且其价格高,性价比差。可见,在现有技术中,覆铜板同时实现低XY轴CTE和低介电性能,并具有良好PCB加工性能比较难。
专利CN 112852104 A公开了一种热固性树脂组合物及其应用,所述热固性树脂组合物包括如下组分:环氧树脂、活性酯、苯并噁嗪树脂以及填料。所述热固性树脂组合物制备得到的覆铜板具有较低的介电性能和较低的XY轴热膨胀系数,但是随着5G对材料越来越高的需求,其介电性能仍然显得不够低,且由于加了不少的中空球,其漂浮问题仍难以完全解决,机械加工性能也会一定程度受到影响,无法满足印制线路板越来越高层数的应用要求。

为更清楚地阐述本发明的特征和功效,下面结合具体实施例来对本发明进行详细说明。
具体实施方式

表2特性评估
表3组合物的配方(二)(重量份)
表4特性评估
备注:机械冲击韧性:从◎◎◎到◎表示冲击韧性由好到差。
根据以上测试结果,可以观察到以下现象。
实施例1到实施例10相比于比较例1,实施例1到实施例9使用了含不饱和键支链改性碳环主链树脂,由于其分子具有全碳环主链,又含有较多不饱和反应基团,固化后组合物具有较高交联密度,使用其制备的基材具有极其优异的尺寸稳定性,降低了组合物在平面方向热膨胀系数,提高了材料的耐热性;碳环主链结构使其具有一定的自阻燃特性,使用时加入较少的阻燃剂就可以实现组合物的阻燃UL94-V0级。
实施例6相比于比较例2,比较例2使用的含不饱和键支链改性碳环主链树脂和多马来酰亚胺比例搭配超出界限,含不饱和键支链改性碳环主链树脂过多,会导致材料玻璃强度降低,多马来酰亚胺过少,固化交联密度有一定降低,导致基材热膨胀系数变大,机械加工性能也会有一定变差。
实施例5相比于比较例3,比较例3使用二苯甲烷双马来酰亚胺,其为双官能团双马来酰亚胺树脂,当量相对较大,固化时材料交联密度不足,所以导致热膨胀系数明显较大。
实施例9相比于比较例4,比较例4由于未使用含不饱和键支链改性碳环主链树脂和多马来酰亚胺,导致材料交联密度降低,XY轴热膨胀系数变差,耐热性也明显变差。
测试方法:
(1)吸水性:为PCT蒸煮1h前后重量差值相对于PCT前样品重量的比率。
(2)PCT1h+Dip为在121℃105KPa压力锅中蒸煮1h,浸入288℃锡炉中,记录爆板分层时间。
(3)耐热裂时间T300(TMA):按照IPC-TM-650 2.4.24方法进行测定。
(4)热膨胀系数Z轴CTE(TMA):按照IPC-TM-650 2.4.24方法进行测定。
(5)热膨胀系数(XY轴CTE):按照IPC-TM-650 2.4.24C所规定的CTE测试方法进行测定。
(6)玻璃化转变温度Tg(TMA):按照IPC-TM-650 2.4.24方法进行测定。
(7)介电常数及介质损耗值:按照SPDR方法测试10GHz下的介电常数和介电损耗因素。
(8)剥离强度(PS):按照IPC-TM-650 2.4.9规定测试
(9)燃烧性:依据UL 94垂直燃烧法测定。
(10)机械冲击韧性:使用漆膜冲击器固定高度进行冲击性试验,对比十字纹情况。
(11)流胶:使用2116*6RC56压板后,板边超出玻璃布的树脂的宽度。
综上所述,本发明的无卤高频高速低膨胀系数树脂组合物,可以同时实现低XY轴膨胀系数及低介电性能,其中XY轴膨胀系数可以做到10ppm/℃,介电损耗可以做到0.0055(at 10GHZ)并且具有优异的耐热性,树脂组合物制备的预浸料流动性好,有优异的冲击韧性,可满足多层板及高密度互联的应用需求,可在封装和高速等领域应用。
以上所述,仅是本发明的较佳实施例而已,并非对本发明的技术范围作任何限制,故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
