Description

一种陶瓷基锰覆线PCB及其制备方法
技术领域
本发明涉及电子元器件技术领域,尤其涉及一种陶瓷基锰覆线PCB。
背景技术
陶瓷基板作为电路元件及互连线承载体,广泛应用于军事和空间技术通讯、计算机、仪器仪表、电力电子设备、汽车、日用家电、办公自动化等各个领域。如LED照明电路、点火模块、晶闸管散热、大功率模块电路、可控硅整流器、大功率晶体管、半导体激光器、固体继电器、开关电源、大功率集成电路及封装等要求绝缘又高散热的大功率器件上。
传统陶瓷基板采用银作覆线,成本较高,不符合经济原则。
同时,现有技术生成银覆钱时,多使用气氛烧付还原法,需要高温下进行,耗费大量能源和氮气。
发明内容
针对现有技术中存在的问题,本发明提供了一种成本较低的陶瓷基锰覆线PCB及其制备方法。
为实现上述目的,本发明采用的技术方案如下:
PCB基板为陶瓷,覆线成分为锰。
进一步,陶瓷基板的成分为氧化铝或氮化铝。
本发明还提供一种陶瓷基锰覆线PCB的制备方法,其工艺步骤如下:
(1)准备陶瓷板;
(2)使用热喷涂法,在陶瓷板上生成锰覆线层;
(3)使用CNC加工方式,对覆线层进行修整,生成电子线路;
(4)对产品进行清洗
本发明具有如下有益效果:
锰是耐高温金属,与陶瓷能良好结合,导电性好,可焊接,但其成本远较银为低。
采用本发明陶瓷基锰覆线PCB的制备方法,不需要气氛烧付还原工序,可节省大量的能源,且工序简单,效率高。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将对本发明作进一步地详细描述。
实施例1:
选取氮化铝板作为陶瓷基,锰金属作为覆线材料,生产陶瓷基锰覆线PCB,成本低,耐热性好。
实施例2:
一种陶瓷基锰覆线PCB的制备方法
(1)选取氮化铝板作为PCB基板,进行清洗、干燥后,固定在装置上;
(2)将锰金属装入热喷涂喷枪中,将喷枪接入电源或气源,同时接入压缩空所,将喷枪对准固定好的PCB基板,将锰金属喷到基板表面上;
(3)将表面覆的锰金属层的PCB基板放在CNC加工中心中加工,切削出电子线路,从而生成陶瓷基PCB。
(4)对陶瓷基PCB进行清洗。
以上所揭露的仅为本发明一种较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明权利要求所作的等同变化,仍属本发明所涵盖的范围。
