DEK的地平线的SMT丝网印刷机精度和重复性测试。 4TechUSA.com

这个视频是在一个DEK的地平线“翻印”的测试部分,这是我们在评估的机械性能和装运前我们的客户机的性能测试策略的一个方面。这与其他几人相结合的测试,量化,并提供所需的信心水平。

在此转载测试,PCB是印刷和删除输出输送轨道,运回转载输入跟踪没有任何干预。机器视觉定位系统与电路板支持战略都必须在最佳性能水平或焊料的存款,将相应地出现快速恶化。

显然,有一个主机,这个测试的结果作出贡献的其他因素。但是,我们解决前阶段的处理,以达到性能测试模型的特点。

您可能会注意到几个存款/垫后几张版画成为抹黑。如果你仔细观察,你也将看到的人/导致运输PCB背面输入输送涂抹他们与他的拇指。处理湿板的危害。


一些利益,是我们共同复印机安装直在测试和视频分纸的使用。这提供了良好的的对比,协助检查方法,并降低对结果子直影响。我们开始使用这种方法在焊料印刷早年援助过程中设置和验证,除了消除需要去除焊料存款和士兵迁移,以避免所有这些困难,洁净区。

This video is of a DEK Horizon during the "REPRINT" test portion, that is one aspect of our test strategies used in evaluating the machine capability and performance before shipping the machine to our Customers. This test combined with several others quantifies and provides the confidence level required.

In this reprint test, the PCB is printed and removed from the output conveyor track and transported back to the input track for reprint without any intervention. The machines vision and positioning systems along with the board support strategy must all be at optimal performance levels or the solder deposits will exhibit rapid deterioration accordingly.

Clearly, there are a host of other factors that contribute to the results of this test. However, we address them at prior stages of processing to achieve characteristic performance for the model tested.

You may notice a couple of deposits/ pads became smeared after a few prints. If you watch carefully, you will also see the person/cause transporting the PCB back to the input conveyor smear them with his thumb. The hazards of handling wet boards.


Of interest to some, is our use of common copier paper mounted to the sub straight in testing and videos. This provides good contrasting, aiding inspection methods and reduces sub straight influence on results. We began using this method in the early years of solder printing to aid process setup and verification, in addition to eliminating the need to remove solder deposits and avoid solider migration to all those difficult to clean areas.


This process and equipment are available for hands on demonstration, please visit us at 4TechUSA.com to make arrangements, or if you have questions.
