PCB的应用越来越广泛，其独特的优点包括：可高密度化、高可靠性、可设计性、可生产性、可测试性、可组装性及可维护性等等，就这决定了对其产品合格率的要求是极高的。人眼检测是满足不了的，山东红宝自动化提供的视觉缺陷检测设备能够针对PCB生产制作过程中出现的问题，定制视觉缺陷检测方案。
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板的过程中容易出现哪些问题呢？
So, what problems are prone to occur in the process of making PCB?
1、贴片元器件在生产过程中易出现孔洞、剥落、污点等缺陷，由于缺陷小，传统算法需要耗费大量的时间对缺陷进行定制化开发，并且在进行灰度阈值分割时，易将微小的缺陷分割出去，很难保证在高速生产线上实现零缺陷检测的要求；
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板上存在很多焊点和细小零件，字符识别采集图像时背景较为复杂，干扰因素多，造成字符定位和识别不准确，加上零件本身反光，会出现识别信息不全、误识别以及识别速度慢等情况，无法满足实际生产检测过程中对PCB板字符识别的需求；
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板在焊接元器件过程中，需要检测每个元器件位置是否正确、元器件是否缺失等情况，传统算法无法对多种电子元器件定位识别，而且定制开发需要耗费大量的时间，容易受外界因素影响，导致错误定位或元器件缺失，直接影响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.
