AbstractIn SMT chip processing of electronic processing factory, there is an indispensable equipment to ensure PCBA processing quality, that is AOI automatic optical detection equipment.

In SMT chip processing of electronic processing factory, there is an indispensable equipment to ensure PCBA processing quality, that is AOI automatic optical detection equipment. Nowadays, AOI automatic optical inspection equipment is an indispensable process inspection equipment in SMT chip processing. In many electronic processing plants, AOI is needed to find the possible defects in PCBA, so as to find out the defects and solve them in time in the process of PCBA processing, so as to ensure that every PCBA delivered to the customer has no problems. Next, we will introduce the AOI automatic optical testing equipment of SMT electronic processing factory.




Through defect inspection, we can find out what's wrong with PCBA. After reflow soldering, AOI can detect all kinds of defects in SMT chip processing, and then according to the number and severity of defects, we can decide whether this batch of PCBA is directly scrapped or can be repaired. And we can observe whether the problems in PCBA OEM are small amount random or large number of regular problems. If there is regularity, we need to find out the causes of the defects, and then fundamentally solve them, so as to avoid the same problems in PCBA patches.



AOI centered defect prevention is a method used by PCBA factories to generate inspection and measurement data from a large number of existing AOI equipment. This method uses many statistical process control / Six Sigma rules, and it avoids the trouble of entanglement in details, so that users can continue to carry out real-time analysis, find out the exact reason, and carry out predictive analysis.



Using AOI flexibly in production line and taking measures to prevent defects can shorten the feedback time of current production line status. In this way, the printing and mounting errors can be solved more quickly, and the final defect rate per million of the production line can be reduced, so that it can be maintained at a low level.



In the electronic processing plant industry, PCBA quality is the focus of all customers, for PCBA factory, quality is also the core of survival and development. Therefore, PCBA processing plants must constantly improve product quality, in order to maintain the leading position in the market, ensure product quality, reduce internal costs and reduce warranty costs, which are the driving force and source of the development of electronic processing plants.
