Description

一种印制线路板自动化控制蚀刻系统及工序
技术领域
本发明涉及印制线路板领域,尤其涉及一种印制线路板自动化控制蚀刻系统及工序。
背景技术
传统的外层蚀刻工艺主要流程包括:退膜->蚀刻->退锡->出板。其中,在退锡之后,需要人为的手持百倍镜观测线宽大小,若不满足线宽要求,则返回上一道工序重新调整蚀刻工艺参数,这种人为测试蚀刻结果,会存在测试误差,且往往蚀刻精度只能控制在±20%,测试过程中还在生产,这样会生产一部分产品,调整过程中也在生产,也会生产一部分产品,测试及调整过程中产品的品质不能实时监测,而对于有阻抗要求的产品,因为线宽只能控制在±20%,对最终产品品质有较大影响。
发明内容
本发明要解决的技术问题之一,在于提供一种印制线路板自动化控制蚀刻系统,提高蚀刻精度,降低生产成本,提高生产质量和效率。
本发明要解决的技术问题之一是这样实现的:一种印制线路板自动化控制蚀刻系统,包括控制器、线宽检测仪、蚀刻设备、传感器和机械手,所述线宽检测仪、蚀刻设备与所述机械手分别与控制器连接,受所述控制器控制,所述传感器与控制器连接,向控制器传输信号,所述传感器安装于蚀刻设备之后的传输带的对应位置。
本发明要解决的技术问题之二,在于提供一种印制线路板自动化控制蚀刻工序,提高蚀刻精度,降低生产成本,提高生产质量和效率。
本发明要解决的技术问题之二是这样实现的:一种印制线路板自动化控制蚀刻工序,需提供上述系统,所述工序包括:
a、获取经图形电镀后的PCB板;
b、退膜;
c、蚀刻;
d、退锡;
e、烘干;
f、所述控制器控制机械手抓取部分烘干后的PCB板,置于固定位置,启动线宽检测仪检测固定位置的线宽,并将线宽数据传送给所述控制器,控制器判断所述线宽数据是否落入一预设范围,若是,则进入下一工序,否则根据线宽检测仪检测的线宽调整蚀刻设备参数,使线宽在所述预设范围。
进一步的,所述下一工序为AOI扫描检测。
本发明具有如下优点:采用线宽检测仪器接入印制线路板生产线中,取代人工用百倍镜测试线宽的操作,减少测试误差,提高蚀刻精度,减少生产线人工成本,提高生产质量和效率。
附图说明
下面参照附图结合实施例对本发明作进一步的说明。
图1为本发明一种印制线路板自动化控制蚀刻系统的逻辑框图。
图2为本发明一种印制线路板自动化控制蚀刻方法的执行流程图。
具体实施方式
如图1所示,本发明的一种印制线路板自动化控制蚀刻系统,包括控制器、线宽检测仪、蚀刻设备、传感器和机械手,所述线宽检测仪、蚀刻设备与所述机械手分别与控制器连接,受所述控制器控制,所述传感器与控制器连接,向控制器传输信号,所述传感器安装于蚀刻设备之后的传输带的对应位置。其中,线宽检测仪可采用型号为XK25的线宽检测仪。在蚀刻设备对PCB板进行蚀刻之后,传感器监测到PCB板并将信号传送给控制器,控制器通过机械手根据预先设定的比例随机抽取部分PCB板到对应工位上,启动线宽检测仪对固定于某一位置上的线宽进行拍摄放大与测量,将测量结果传送给控制器,由控制器判断测量结果是否落在一预设的合格范围内,若是,通过机械手将PCB板放回原位进入下一道工序,否则,根据线宽检测仪检测的线宽调整蚀刻设备参数,使线宽在所述预设范围;
如图2所示,本发明的一种印制线路板自动化控制蚀刻工序,需提供上述系统,所述工序包括:
a、获取经图形电镀后的PCB板;
b、退膜;
c、蚀刻;
d、退锡;
e、烘干;
f、所述控制器控制机械手抓取部分烘干后的PCB板,置于固定位置,启动线宽检测仪检测固定位置的线宽,并将线宽数据传送给所述控制器,控制器判断所述线宽数据是否落入一预设范围,若是,则进入下一工序,否则根据线宽检测仪检测的线宽调整蚀刻设备参数,使线宽在所述预设范围,所述预设范围为预设的一最佳值的±10%误差范围内。
较佳的,所述下一工序为AOI扫描检测,即采用全检或抽检的方式对线路图形进行缺陷检测,包括板面连线是否有断线,残铜、缺口是否符合IPC标准的规定等,之后再进行常规的印制板制作。
本发明用在线线宽自动测试取代人工用百倍镜测试,减少测试误差;线宽测试结果与蚀刻机控制系统整合对接,实现联网实时对接,通过在线实时控制蚀刻工艺参数,实现蚀刻工序自动化,减少产线人工成本,提高蚀刻精度,让线宽可以控制在误差±10%,提高产品质量。
