江南体育网(中国)有限公司官网 AOI detection applICation of aoi in 江南体育网(中国)有限公司官网 detection
Automatic optical inspection, also known as automatic optical inspection instrument, is an automatic optical inspection device applied to surface mount production line, which can effectively detect printing quality, installation and welding joints The core of AOI is a CCD CAMera system used to capture images, but after a series of calculations, such as image processing cards and computer processing software systems, they are compared with standard images to find defects and generate files AOI can find and eliminate errors in the early stage of the assembly process to achieve good process control Early detection of defects will avoid sending defective products to the assembly stage of the subsequent process. AOI will reduce maintenance costs and avoid scrapping 江南体育网(中国)有限公司官网 boards that cannot be repaired
Circuit board

江南体育网(中国)有限公司官网 for short are abstracts for assembling electronIC parts, and the manufacturing quality of 江南体育网(中国)有限公司官网s directly affects the reliability of electronic products With the further development of electronic assembly towards the mixed technology of high-density and SMAll size 江南体育网(中国)有限公司官网s, the demand for automatic optical inspection (AOI) systems for 江南体育网(中国)有限公司官网 inspection is also increasing in order to reduce the number of defective circuit boards entering the next step Big
AOI system has scientific and technological advantages that other detection schemes and traditional detection methods cannot match, and has been widely used in 江南体育网(中国)有限公司官网 detection. Its high speed, middle and high gear and high-precision features are favored by users in the industry.
1. The 江南体育网(中国)有限公司官网 inspection system checks and corrects 江南体育网(中国)有限公司官网 defects. The cost during process monitoring is much lower than that after final testing and inspection.
2. Repetitive errors can be detected as early as possible, such as incorrect placement displacement or pallet installation.
3. The combination of statistical analysis function of 江南体育网(中国)有限公司官网 detection technology and SPC process management technology provides a powerful weapon for timely improvement of SMT production process, and the yield of 江南体育网(中国)有限公司官网 assembly has been significantly improved. With the continuous expansion of modern manufacturing industry, production control becomes more and more important, and the demand for SPC data is also growing.
4. It can meet the test requirements of 江南体育网(中国)有限公司官网 assembly density. With the substantial increase in the assembly density of electronic products, some traditional testing technologies, such as ICT, can no longer meet the development requirements of SMT technology, and 江南体育网(中国)有限公司官网 testing technology will not be affected by these factors.
5. The test program of 江南体育网(中国)有限公司官网 test equipment can be generated directly from CAD data. Compared with ICT, because no special fixture is required, the test cost is also greatly reduced.
6. It can keep up with SMT production line According to the test results of 江南体育网(中国)有限公司官网 detection technology, it can reach the speed of 0 1 second/current frame, which can meet the requirements of online detection
7. The high reliability of manual visual inspection always has its limitations, while 江南体育网(中国)有限公司官网 inspection technology testing avoids the shortcomings in this regard, and can maintain better accuracy and reliability.
