Description

一种软硬结合板半PTH槽孔加工工艺
技术领域
本发明涉及一种软硬结合板半PTH槽孔加工工艺,属于软硬结合板技术领域。
背景技术
软硬结合板,就是柔性线路板与硬性线路板,经过压合等工序,按相关工艺要求组合在一起,形成的具有FPC特性与PCB特性的线路板。软硬结合板在加工半PTH槽孔时,由于孔壁上的铜薄薄一层,铜呈软性,在成型时受到铣刀的挤压,将铜挤入孔内不能够被铣刀切掉,导致产品到成品时出现卷铜及披锋状况,影响客户端上件效率,人工返修时困难且耗时,比较容易产生不良报废。
发明内容
针对上述缺陷,本发明的目的在于提供一种解决成型时产生的披锋及卷铜,降低产品不良率,减少人工返修率,提升客户端上件成功率的一种软硬结合板半PTH槽孔加工工艺。
为此本发明所采用的技术方案是:
包括以下步骤:开料→钻孔→内层线路→贴覆盖膜→冲板→叠板→压合→打靶→铣边框→钻孔→沉铜→一铜→外层线路→电镀铜锡→二次锣槽→SES→AOI→阻焊→字符→表面处理→电测→成型→FQC→FQA→包装→入库。
本发明的优点是:
本发明解决了成型时产生的披锋及卷铜,降低产品不良率,减少人工返修率,提升客户端上件的成功率。
具体实施方式
一种软硬结合板半PTH槽孔加工工艺,包括以下步骤:开料→钻孔→内层线路→贴覆盖膜→冲板→叠板→压合→打靶→铣边框→钻孔→沉铜→一铜→外层线路→电镀铜锡→二次锣槽→SES→AOI→阻焊→字符→表面处理→电测→成型→FQC→FQA→包装→入库。
