FR-4系统介绍

FR-4系统介绍

FR-4产品介绍FR4口头上是那么读，但是正规的书面型号是FR-4FR-4是一种耐燃材料等级的代号，所代表的意思是树脂材料经过燃烧状态必须能够自行熄灭的一种材料规格，它不是一种材料名称，而是一种材料等级，因此目前一般电路板所用的FR-4等级材料就有非常多的种类，但是多数都是以所谓的四功能(Tera-Function)的环氧树脂加上填充剂(Filler)以及玻璃纤维所做出的复合材料。

FR-4环氧玻璃布层压板，根据使用的用途不同，行业一般称为：FR-4 Epoxy Glass Cloth,绝缘板，环氧板，环氧树脂板，溴化环氧树脂板，FR-4，玻璃纤维板，玻纤板，FR-4补强板，FPC补强板，柔性线路板补强板，FR-4环氧树脂板，阻燃绝缘板，FR-4积层板，环氧板，FR-4光板，FR-4玻纤板，环氧玻璃布板，环氧玻璃布层压板，线路板钻孔垫板。

主要技术技术特点及应用：电绝缘性能稳定，平整度好，表面光滑，无凹坑，厚度公差标准，适合应用于高性能电子绝缘要求的产品，如FPC补强板，PCB钻孔垫板，玻纤介子，电位器碳膜印刷玻璃纤维板，精密游星齿轮(晶片研磨)，精密测试板材，电气（电器）设备绝缘撑条隔板，绝缘垫板，变压器绝缘板，电机绝缘件，研磨齿轮，电子开关绝缘板等。

FR4环氧玻璃布层压板表面颜色有:黄色FR-4,白色FR-4,黑色FR-4,篮色FR-4等.FR-4是PCB使用的基板，是板料的一种类别。

板料按增强材料不同，主要分类为以下四种：1）FR-4：玻璃布基板2）FR-1、FR-2等：纸基板3）CEM系列：复合基板4）特殊材料基板（陶瓷、金属基等）FR-4由专用电子布浸以环氧酚醛树脂等材料经高温高压热压而成的板状层压制品。

特点：具有较高的机械性能和介电性能，较好的耐热性和耐潮性并有良好的机械加工性。

用途: 电机、电器设备中作绝缘结构零部件，包括各式样之开关`FPC补强电器绝缘`碳膜印刷电路板`电脑钻孔用垫`模具治具等（PCB测试架）并可在潮湿环境条件和变压器油中使用。
