江门印刷电路板制作流程

2020-10-29 49

  印制电路板,又称印刷线路板,它是重要的部件,是电子元器件的支撑体,是电子元器件电气衔接的载体。由于它是选用电子印刷术制作的,故被称为“印刷”电路板。印制电路板的制作流程14步走:

  注册客户编号;

  开料。流程:大板料→按MI要求切板→锔板→啤圆角磨边→出板;

  钻孔。流程:叠板销钉→上板→钻孔→下板→查看修理;

  沉铜。流程:粗磨→挂板→沉铜自动线→下板→浸稀H2SO4→加厚铜;

  图形搬运。流程:(蓝油流程):磨板→印一面→烘干→印二面→烘干→爆光→冲影→查看;(干膜流程):麻板→压膜→静置→对位→曝光→静置→冲影→查看;

  图形电镀。流程:上板→除油→水洗二次→微蚀→水洗→酸洗→镀铜→水洗→浸酸→镀锡→水洗→下板;

  退膜。流程:水膜:插架→浸碱→冲洗→擦拭→过机;干膜:放板→过机;

  蚀刻。是利用化学反应法将非线路部位的铜层腐蚀去除;

  绿油。流程:磨板→印感光绿油→锔板→曝光→冲影;磨板→印一面→烘板→印二面→烘板;

  字符。流程:绿油终锔后→冷却静置→调网→印字符→后锔

  镀金手指。流程:上板→除油→水洗两次→微蚀→水洗两次→酸洗→镀铜→水洗→镀镍→水洗→镀金;镀锡板 (并排的一种工艺),流程:微蚀→风干→预热→松香涂覆→焊锡涂覆→热风平坦→风冷→洗涤风干;

  成型。经过模具冲压或数控锣机锣出客户所需求的形状;

  测验。流程:上?!虐濉庋椤细瘛鶩QC目检→不合格→修理→返测验→OK→REJ→作废;

  终检。流程:来料→查看材料→目检→合格→FQA抽查→合格→包装→不合格→处理→查看OK。
