Abstract

本实用新型是对散热PCB板的改进,它包括PCB基板,在所述PCB基板上散热区域敷设铜皮层,然后在所述铜皮层上涂覆介质绿油;所述铜皮层由单个圆形铜皮组成,并且所述圆形铜皮为阵列分布;所述铜皮层可以敷设在所述PCB基板散热区域两侧的任意一侧。本实用新型提供了一种在PCB正反两侧的任一侧敷设铜皮,避免铜皮直接裸露在空气中,有效解决电气安全距离限制的印刷电路板的散热。

Description

一种散热PCB板
技术领域
本实用新型涉及印刷电路板,具体说是涉及一种限制区域内散热印刷电路板。
背景技术
随着高频电子讯号的广泛使用,在印刷电路板(PCB)上芯片的元器件所产生的热量,尤其是大功率元器件工作时产生的热量会对元器件造成很大的损害,需要利用散热或冷却方法帮助将热能排出,而且现在电子元器件的集成度越来越高,PCB板的功率密度越来越高,传统的散热方式通过在PCB板基层敷设长方形锡窗散热,锡窗裸露在空气中,在电气安全距离有严格要求的时候,使用受到限制,且开锡窗只能开在PCB板的一侧。
发明内容
发明目的:本实用新型的目的在于克服上述现有技术的不足,提供一种在PCB正反两侧的任一侧敷设铜皮,避免铜皮直接裸露在空气中,有效解决电气安全距离限制的印刷电路板散热。
技术方案:为了解决上述技术问题,本实用新型采用了这样一种散热PCB板,包括PCB基板,在所述PCB基板上散热区域表层敷设铜皮层,然后在所述铜皮层上涂覆介质绿油。
本实用新型所述铜皮层由单个圆形铜皮组成,并且所述圆形铜皮为阵列分布。
本实用新型所述铜皮层可以敷设在所述PCB基板散热区域两侧的任意一侧。
有益效果:本实用新型可在PCB板正反两侧的任意一侧敷设铜皮散热,并有效地解决PCB板散热时电气安规间距的限制。
附图说明
图1是PCB散热板元件面布局图;
图2是散热PCB板的结构层示意图。
具体实施方式
如图1、图2所示,散热PCB板,包括PCB基板1,在所述PCB基板1上散热区域2敷设铜皮层3,然后在所述铜皮层3上涂覆介质绿油4;所述铜皮层3由单个圆形铜皮5组成,并且所述圆形铜皮5为阵列分布;所述铜皮层3可以敷设在所述PCB基板1散热区域2两侧的任意一侧,本实用新型所述的散热PCB板,由中间层基材6、附合在中间基层6两侧的环氧玻璃布层压板7、附合在环氧玻璃布层压板7两侧的铜皮层3和附合在铜皮层3两侧的介质绿油层4组成,该散热PCB板有效地解决PCB板散热时电气安规间距的限制。
