Abstract

本实用新型涉及一种酚醛纸基光屏蔽单面覆铜箔层压板，适用于紫外线强烈处的灯具和太阳能设施等作印刷线路板的基板。所述层压板是在酚醛纸基(2)表面复合一层铜箔(1)，所述酚醛纸基(2)包括3～8层木纤维绝缘纸，所述木纤维绝缘纸浸有黑色酚醛树酯。本实用新型具有光屏蔽功能，不易老化，大大延长了元器件的使用寿命。

Description

酚醛纸基光屏蔽单面覆铜箔层压板
(一)技术领域
本实用新型涉及一种层压板。适用于紫外线强烈处的灯具和太阳能设施等作印刷线路板的基板。属复合材料技术领域。
(二)背景技术
在本实用新型作出以前，以往用于紫外线强烈处的灯具和太阳能设施等作印刷线路板的基板，是在基板表面外涂黑色涂层。时间长了元器件易老化，元器件使用寿命短。
(三)发明内容
本实用新型的目的在于克服上述不足，提供一种元器件使用寿命长的酚醛纸基光屏蔽单面覆铜箔层压板。
本实用新型的目的是这样实现的：一种酚醛纸基光屏蔽单面覆铜箔层压板，所述层压板是在酚醛纸基表面复合一层铜箔，所述酚醛纸基包括3～8层木纤维绝缘纸，所述木纤维绝缘纸浸有黑色酚醛树酯，构成酚醛纸基。
本实用新型采用木纤维绝缘纸浸有黑色酚醛树酯，构成酚醛纸基，具有光屏蔽功能，不易老化，大大延长了元器件的使用寿命。
(四)附图说明
图1为本实用新型酚醛纸基光屏蔽单面覆铜箔层压板的断面结构示意图。
图中：铜箔1、酚醛纸基2。
(五)具体实施方式
参见图1，本实用新型涉及的酚醛纸基光屏蔽单面覆铜箔层压板，所述层压板是在酚醛纸基2表面复合一层铜箔1，所述酚醛纸基2包括3～8层(图中有6层)木纤维绝缘纸，所述木纤维绝缘纸浸有黑色酚醛树酯，构成酚醛纸基2。其制备方法如下：木纤维绝缘纸→浸渍黑色酚醛树酯→烘干→分切→酚醛纸基→履铜箔→压机成型→成品。
