PCB的應用越來越廣泛，其獨特的優點包括：可高密度化、高可靠性、可設計性、可生產性、可測試性、可組裝性及可維護性等等，就這決定了對其產品合格率的要求是極高的。人眼檢測是滿足不了的，山東紅寶自動化提供的視覺缺陷檢測設備能夠針對PCB生產制作過程中出現的問題，定制視覺缺陷檢測方案。
PCB is more and more widely used. Its unique advantages include: high density, high reliability, designability, producibility, testability, assembly and maintainability, which determines that the requirements for its product qualification rate are very high. Human eye detection cannot be satisfied. The visual defect detection equipment provided by Shandong Hongbao automation can customize the visual defect detection scheme for the problems in the PCB production process.
那么，在制作PCB板的過程中容易出現哪些問題呢？
So, what problems are prone to occur in the process of making PCB?
1、貼片元器件在生產過程中易出現孔洞、剝落、污點等缺陷，由于缺陷小，傳統算法需要耗費大量的時間對缺陷進行定制化開發，并且在進行灰度閾值分割時，易將微小的缺陷分割出去，很難保證在高速生產線上實現零缺陷檢測的要求；
1. Patch components are prone to defects such as holes, spalling and stains in the production process. Due to the small defects, the traditional algorithm needs to spend a lot of time on customized development of defects, and it is easy to separate small defects in gray threshold segmentation, so it is difficult to meet the requirements of zero defect detection in high-speed production line;
2、PCB板上存在很多焊點和細小零件，字符識別采集圖像時背景較為復雜，干擾因素多，造成字符定位和識別不準確，加上零件本身反光，會出現識別信息不全、誤識別以及識別速度慢等情況，無法滿足實際生產檢測過程中對PCB板字符識別的需求；
2. There are many solder joints and small parts on the PCB board. When character recognition collects images, the background is complex and there are many interference factors, resulting in inaccurate character positioning and recognition. In addition, the reflection of the parts themselves will lead to incomplete recognition information, false recognition and slow recognition speed, which can not meet the needs of PCB board character recognition in the actual production and detection process;
3、PCB板在焊接元器件過程中，需要檢測每個元器件位置是否正確、元器件是否缺失等情況，傳統算法無法對多種電子元器件定位識別，而且定制開發需要耗費大量的時間，容易受外界因素影響，導致錯誤定位或元器件缺失，直接影響PCB板的性能及生命周期。
3. In the process of PCB welding components, it is necessary to detect whether the position of each component is correct and whether the components are missing. Traditional algorithms can not locate and identify a variety of electronic components, and customized development takes a lot of time. It is easy to be affected by external factors, resulting in wrong positioning or missing components, which directly affects the performance and life cycle of PCB.
