機器視覺檢測技術是保證大批量貼裝生產的最基本的技術，也是必須加以應用和發揮其價值的根本原因。常用的電子材料、活動組件、IC封裝、無源元件和成品電子設備，均采用機器視覺檢測系統促進高質量生產以及降低成本。
Machine vision inspection technology is the most basic technology to ensure mass mount production, and it is also the fundamental reason for its application and value. Machine vision inspection system is used in common electronic materials, active components, IC packaging, passive components and finished electronic equipment to promote high-quality production and reduce costs.
目前，電子產品的表面貼裝元件(SMD)的尺寸已經越來越小，甚至小到只有幾毫米甚至更小，像常見的電子元件如晶體管、電容器、電阻器和其它組件，以在印刷電路板PCB上實現更大的密度的貼裝，實現更多的既有功能。尺寸的不斷減少，以及功能的不斷增加，極大地改進了電子設備的性能。
At present, the size of surface mount components (SMD) of electronic products has become smaller and smaller, even as small as a few millimeters or even smaller, such as common electronic components such as transistors, capacitors, resistors and other components, in order to achieve higher density mounting on printed circuit board PCB and realize more existing functions. The decreasing size and increasing function greatly improve the performance of electronic equipment.
視覺檢測系統產品具有功能非常強大的視覺工具，在這種機器視覺系統的應用下，經過相關技術培訓的專業人員的部署，電子生產工程師能夠利用機器視覺，不斷去滿足苛刻的生產和包裝要求，以確保產品質量和安全，由此可見，機器視覺在工業領域的應用價值。
Visual inspection system products have very powerful visual tools. Under the application of this machine vision system, after the deployment of relevant technical training professionals, electronic production engineers can use machine vision to continuously meet the stringent production and packaging requirements to ensure product quality and safety. Thus, the application value of machine vision in the industrial field can be seen.
機器視覺可以實現通過采用二維和三維方面，去定位托盤上的PCB，引導高速拾放機器人至單個SMD元件進行拾取，將機器人手臂引導回PCB以放置SMD，最后，驗證焊接連接，以確認每根SMD引線是否穿過PCB或者經過安裝孔。在這些對精度要求比較高的領域，機器視覺的優勢是非常明顯的，它能夠完成人甚至機器人都無法完成的定位工作。
Machine vision can use two-dimensional and three-dimensional aspects to locate the PCB on the tray, guide the high-speed pick-up robot to single SMD components for picking, guide the robot arm back to the PCB to place the SMD, and finally verify the welding connection to confirm whether each SMD lead passes through the PCB or through the mounting hole. In these areas with high precision requirements, the advantages of machine vision are very obvious. It can complete the positioning work that people and even robots can not complete.
另外，因為電路板上元件如此密集，如果采用人工方法，是無法進行焊接驗證的。然而，使用機器視覺則不僅可驗證線路板的連接，而且即使出現焊接開裂、回流不足或者其它工藝特征的情況，機器視覺還可以為制造工程師提供缺陷反饋，留下分析數據和依據。
In addition, because the components on the circuit board are so dense, if manual method is used, it is impossible to carry out welding verification. However, the use of machine vision can not only verify the connection of circuit boards, but also provide defect feedback for manufacturing engineers to leave analysis data and basis even in case of welding cracks, insufficient reflow or other process characteristics.
