AOI visual inspection equipment in the process of PCB production, on the one hand, in order to meet the customer’s requirements for traceability, when finding problems, the demand can quickly locate the cause of the problem and the affected product scale; on the other hand, the change of product structure also makes the original system unable to meet the demand, so the introduction of big data skills is imperative.
With the development of information technology, the method of data generation is also changing, the data heap is becoming more and more agile, the storage capacity is also constantly increasing, and the processing speed of accounting machine is soaring, which directly promotes the development of big data skills based on data storage (memory and hard disk), data transmission (Network) and data accounting (CPU and distributed processing).
Big data is in accordance with the development logic of information and communication skills to realize the natural change from the progress of production power to the intelligent production stage. The ubiquitous information identification and perception system and collection terminal have collected massive data for us. The computing skills represented by the distributed accounting system have provided us with strong accounting ability. Finally, we have built a parallel network with Physics International Digital virtual international, and our policy is to make this digital virtual international appear in the form of data vision.
The value of data is timely, and the earlier the analysis, the faster the problem response or response can be obtained. AOI testing results can only be recorded by technical methods in the early stage. AOI is only used as production equipment to mark or repair the detected defects, or for first article inspection and sampling inspection.
With the improvement of customer demand and the spread of office automation, enterprises began to input the AOI test results (defect classification information) into the computer and carry out the corresponding statistical analysis, and then reflect the analysis results to the relevant parts and ask for improvement. Obviously, the timeliness of this processing method is still too low. Recall the PCB Production Traceability system, start only in the product production cycle, if the product is abnormal, will affect the whole batch of products.
