Description

一种绝缘胶膜材料及其制备方法和应用 技术领域
本发明属于电子封装材料技术领域,具体涉及一种绝缘胶膜材料及其制备方法和应用。
背景技术
随着电子信息技术的发展,特别是近年来以可穿戴电子、智能手机、超薄电脑、无人驾驶、物联网技术和5G通讯技术为主的快速发展,对电子***的小型化、轻薄化、多功能、高性能等方面提出了越来越高的要求。集成电路线路线宽由1997年的3μm,发展为2010年的0.05μm,到现在的0.01um,甚至更小。与之相匹配的的PCB线路尺寸要求由1997年的300μm降至如今的30μm,甚至更低。采用常规的减成法制备小于30μm的线路已经非常困难,并且有很多的局限性。
此外,现有技术中一般将填料直接加入至树脂体系中,或者引入偶联剂增强在树脂体系中的分散性,填料粒子与树脂基体之间的结合力较差,在应用过程中容易出现填料与树脂脱离、开裂等现象,影响电路板的加工性和可靠性。

本发明的有益效果是:本发明采用第二固化剂对无机填充材料表面进行处理后,第二固化剂将包覆于无机填充材料表面,将该填料引入聚合物基体后将使得树脂在填充材料表面迅速固化,使得填充材料与聚合物基体间更加紧密的结合并减少孔隙,进而提升绝缘聚合物复合物的玻璃化转变温度(通常在聚合物基体中引入填料后,由于填料表面与聚合物基体间的不良接触而形成的界面、孔隙等将导致聚合物复合物的玻璃化转变温度进一步下降),本发明电子浆料涂布干燥、固化后的产物绝缘聚合物复合物的玻璃化转变温度高于120℃(若固化物玻璃化转变温度低于120℃,使用该材料制备的电子器件在使用过程中容易失效,不利于器件的长期稳定工作)。此外该方法也将在一定程度上提升聚合物复合物的绝缘性能和机械性能。
本发明绝缘胶膜材料,可应用于印刷线路板(PCB)、基板、载板等半导体电子封装,实现精细电子线路的制造。
