单面铝基板和双面铝基板的加工工艺
2019-05-05 Information source: Tengchuangda

 一:较之单面铝几板,双面铝基板多一个压合工艺!但价格一般差距很大,生产工艺难度很高!


    二,双面铝基板为什么要钻两次孔


      由于直接在铝表面不易镀上铜,所以要先将铝板钻穿,在铝表面覆一层树脂。


      具体操作如下:


      铝基第一次转孔--->压合(给孔内填上树脂)--->第二次转孔(同心圆)--->电镀......


    三,制作流程区别


单面铝基板:铝板做前处理加高导热绝缘层再加铜箔经高温强压成型后便是铝基板. 双面铝基板:铝板机加工后做前处理及孔内绝缘加双面高导热绝缘层再加双面铜箔经高温强压成型后机加工图形转移再机加成型就是双面铝基板了;{成品}多层板:图形转移后层压再图形转机加工成型{双层线路}多层板要看产品结构及加工要求来定,
