Description

一种电路板
技术领域
本实用新型涉及电路板领域,尤其涉及一种陶瓷基材电路板。
背景技术
通常的线路板都是用环氧树脂玻璃纤维布作为基材,再在基材上制有印制电路,这种电路板通常散热性能差,通常不能与有较高发热的电子元器件连接,如LED的灯珠等。与此同时,如遇电路板发生震荡,焊接电路板上面的元器件容易剥离,焊脚易锡裂,削弱了电路板的安全性。
实用新型内容
    本实用新型的目的,在于提供一种散热性能好的陶瓷材料电路板,并且元器件固定牢固的方法。 
    本实用新型是所采用的技术方案是:一种电路板,包括基板、元器件,元器件焊接在基板上,在元器件的引脚和基板上覆盖一层胶水层;所述基板上开设有一个通孔,电路板通过通孔与接地元件固定连接,所述基板的表面于通孔的周围设有一个镀锡层,镀锡层与接地元件接触且电路板与接地元件保持电性导通,通孔的周围设有用于阻止该镀锡层的锡膏流入该通孔的防焊漆;
进一步,所述基板为陶瓷材质;
进一步,所述的胶水层为无影胶。
本实用新型的电路板结构设计合理,简单实用,陶瓷基板提高了电路板的散热性;元器件固定更加牢固,增强电路板的抗震性。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1 为本实用新型结构示意图。
具体实施方式
由图1可知,电路板是以具有良好散热性的陶瓷材料为基板,所述电路板,还包括电路板1、元器件2,元器件2焊接在电路板1上,在元器件2的引脚和电路板1上覆盖一层胶水层3。
    胶水层3选用无影胶层,加工既方便又不影响柔性电路板的外观。
胶水层3可覆盖在元器件2周边的一部分也可在元器件2四周均有覆盖,当胶水层3覆盖在元器件2的四周时,进一步提高元器件2和电路板1的结合强度。
所述基板上开设有一个通孔4,电路板通过通孔与接地元件固定连接,所述基板的表面于通孔的周围设有一个镀锡层,镀锡层与接地元件接触且电路板与接地元件保持电性导通,通孔的周围设有用于阻止该镀锡层的锡膏流入该通孔的防焊漆。
以上公开的仅为本实用新型的具体实施方式,但是,本实用新型并非局限于此,任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应所述以权利要求的保护范围为准。

Claims (3)
