  1,检测使成本上升
  电子行业专家们一致认为焊接缺陷是由焊膏印刷不良造成的。因此,提高印刷质量、或减少进入下一步工序的有缺陷电路板的数量,将有助于提高最终的质量,并通过降低返修量和减少废品率可实现降低成本的目的。

  1.1,尽早发现缺陷
意甲竞猜   经对在线测试阶段所检测的有缺陷的电路板的返修或报废品所带来的成本进行了大概统计,发现控制印刷工艺会给焊膏印刷带来很多显著的优点。任何一种缺陷都会消耗资金,而印刷后检测只能帮助减少缺陷数量,并不能彻底消除缺陷。但是,事实上在电路板成本没有增加之前,在加工过程中进行检测,以求得尽早识别缺陷,的确能够降低由缺陷所带来的额外成本,提高一次性检验合格率对基础生产线起到很大作用。

  1.2,提高可靠性
  在印刷工艺中附加检测工序可提高组装后电路板的可靠性,原因有两个:首先,检测减少了返修量,此外;返修后的焊点易于损坏,并且比合格的焊点更易破裂。其次,焊膏量不足也有可能形成易破裂的焊点,虽然当时能够通过在线测试,可是以后也会断裂。

  1.3,必要的检测
意甲竞猜   由于更密的引线间距、更小的球栅阵列焊球和更精确的印刷间隙的要求,使更多的PCB组装厂家在组装工艺中增加了焊膏检测工序。而在一些合同组装厂,是根据用户的要求才增设检测步骤。

  2.1,视觉检测
  长期以来一直使用视觉检测这种简单的方法就足以确定样品“合格或不合格”,直到今天更小器件、更高引线数和更细间距元件的问世,才使得这种方法不适用了。使用发光的放大镜或校准的显微镜,由经培训的操作人员检查样品印制板,并确定什么时候需进行校正操作。视觉检测在工艺监测中是成本最低的一种方法,而且在印刷工艺中其校正操作步骡的成本是最合理的。

  2.2,人工激光检测
  为减少缺陷,下一步的操作是使用人工台式舱机检测设备。这些测量工具使用了非接触式激光技术来测量焊膏高度和记录。通过对操作人员稍微进行一下培训,这些设备通常就可产生一致性的结果,不会由于操作人员的不同而使检测结果也不同。

  2.3,内置于锡膏印刷机中的自动检测系统
  几家印刷机制造厂推出了内置式二维和三维焊膏检测系统或故障查找系统。然而,内置于印刷机中的检测系统与丝网印刷机共享硬件,由于丝印机必须在暂停的状态下才能进行检测,所以降低了印刷速度。

  2.4,自动三维在线样品检测设备
  与内置在印刷机中的检测系统相比,自动在线样品检测设备有两个主要优点。首先,由于这种设备是独立的系统,所以可以不利用印刷机的硬件,不需要停机就可进行检测。其次,样品检测设备的测量性能使你能够获得精确的、可重复的测量结果。
