The modern PCB assembly production and manufacture of parts of a large number of using the screen printing machine, SMT machines, reflow stoves and other automation equipment, the basic use of industrial control machinery. Because the data interface and format of the manufacturer are different, the equipment information cannot be shared centrally, and many “information islands” are formed, which cannot be analyzed and processed by the same data. Although most equipment has the ability to collect production process parameters, there is no network connection between devices, the acquisition parameters can only be viewed manually through the screen display or the way disk backups are completed, not the timely response to the overall production. Line, real-time performance. At the same time, manual acquisitions increase the workload, reduce work efficiency, the truth also cannot get the safety.

The characteristics of the PCB assembly industry determining whether there is a connection to the problem will result in a whole series of products in the memo. Therefore, it is necessary to monitor the main production parameters in real time and to find the location of the error and provide the correct alarm information. At the same time, some important parameters are adjusted automatically. You …
