在采用喷砂工艺,将需要喷砂的颗粒物喷砂到镀锡涂层的外表面,其中喷砂颗粒物成采用竹炭粉、有机硅以及木炭粉,通过采用压缩空气为动力形成高速喷射束,将喷料碳粉高速喷砂在镀锡涂层表面,使的镀锡涂层的表面形成涂黑涂层。
所述的涂黑涂层采用黑釉加工方法,黑釉加工方法主要包括呈色剂和有色金属,其中呈色剂采用为氧化铁,有色金属采用锰、钴、铜、铬其中的任何一种;
所述的涂黑涂层采用电镀工艺,在电镀的时候将铜基带放入电镀液中,依靠电镀液对于铜基带进行电镀,电镀后的铜基带外表面形成电镀层,电镀层为黑镍层,在电镀液中加入酸性液体,酸性液体中包含硫氰酸根离子,其中硫氰酸根离子中硫与镍生产黑色的含镍粒子。
相比现有技术,本发明在进行处理焊带外表面涂黑涂层的时候采用多道工序,尤其是采用喷涂工艺,涂刷烘干后能耐高温,使得焊带的外表面形成涂黑涂层,涂黑涂层附着在铜基材的外表面,使得铜基材外表面显著变色且开裂脱落,同时将喷料碳粉高速喷砂在焊带的表面,使焊带表面呈现黑色,黑色的焊带的起到非绝缘状态且起到导电的作用。

涂黑涂层3采用黑釉加工方法,黑釉加工方法主要包括呈色剂和有色金属,其中呈色剂采用为氧化铁,有色金属采用锰、钴、铜、铬其中的任何一种;
涂黑涂层采用电镀工艺,在电镀的时候将铜基带放入电镀液中,依靠电镀液对于铜基带进行电镀,电镀后的铜基带外表面形成电镀层,电镀层为黑镍层,在电镀液中加入酸性液体,酸性液体中包含硫氰酸根离子,其中硫氰酸根离子中硫与镍生产黑色的含镍粒子,酸性液体种加入悬凝剂和絮凝剂,这样可以让焊带在酸性液体中的含镍粒子形成较大颗粒,然后含镍粒子吸附在铜基带外表面形成涂黑涂层,形成涂黑涂层后进行烘干,烘干的时候采用风机烘干机,风机设置在烘干机的底部,然后风机向烘干机输送热风,烘干机的外表面设置有搁置台,搁置台上设置有若干组圆孔,在搁置台上设置有铜条,搁置台和烘干机之间设置有磁性吸铁石,依靠磁性吸铁石固定在烘干机的外表面,搁置台的两侧设置有带有吸水的石英棉,石英棉可以让铜基带在烘干之前进行外表面的吸收电镀液,然后将铜基带搁置在搁置台上进行烘干,风机向烘干机进行吹热风,然后热风吹向搁置台,然后将铜基带进行烘干,烘干后外表面涂覆木炭粉。
上述实施方式仅为本发明的优选实施方式,不能以此来限定本发明保护的范围,本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
