What are the functions of CIM technology in PCB assembly?

In PCBA assembly, CIM is a paperless manufacturing information system based on computer networks and databases that can improve the quality, capacity, and output of circuit assembly. It can control and monitor screen printers, dispensers, placement machines, plug-in machines, and test equipment. And rework workstations and other assembly line equipment.
It mainly has the following functions:
First, the most basic function of CIM is the integration of CAD/CAM, the automatic conversion of manufacturing data required for the realization of CAD data into production equipment, ie, automatic programming, and easy product conversion. Once the product changes, it can be automatically reflected in the machine program, test data and documents, without the need to program each device, which means that the product conversion that can be achieved in the past hours or even days is now several minutes Can achieve.
Second, to provide manufacturability analysis and testability analysis tools, through the manufacturability analysis of the CAD files from the design department, the issue of violation of the placement rules back to the design system, promote the parallel design and manufacturing systems Engineering, to improve the design of a success rate, testability analysis tool can provide designers with complete measurable rate analysis report, help the development engineer to complete the required formal production before the amendment.
Third, arrange the production schedule, consider the parameters of the products to be assembled, the machine occupancy, and the delivery cycle requirements through comprehensive analysis to maximize the production assembly efficiency. CIM can be used for direct, short-term scheduling, or for long-term strategic considerations of plant capabilities.
Fourth, the balance of the production line and process optimization, CIM is a major feature is to automatically balance the product loading, sequencing, component distribution and placement, speed of the equipment to achieve the optimization of the assembly, can properly distribute components to the right The machine or hand assembly process. In short, CIM can monitor the entire assembly process and the quality of the product. In the event of a problem, CIM can provide feedback to the operator or process engineer and indicate the exact location of the problem. The statistical analysis tool collects and analyzes the data in the production process in real time without having to wait for the report to be generated before analysis. It can be said that CIM is a key part of CIMS. It can provide the necessary data for the entire production planning, scheduling and factory management. The fundamental goal of CIM is to achieve fully integrated production control, and CIM is still in development
