CIMS can bring very significant economic benefits for the enterprise: to improve product quality, effective utilization of equipment and flexible manufacturing capabilities, shorten product design cycles and time to market. CIMS has so many advantages, it can be predicted to CIMS in SMT production line will be more extensive.
1.2 SMT production line towards efficient online high production efficiency is the key performance indicators to measure the SMT production line, SMT production lines, production efficiency is reflected in the production efficiency and control efficiency. Production efficiency refers to the capacity of the SMT assembly line equipment. In order to increase productivity efficiency, some of the SMT production line after the reflow oven coupled with a fully automated on-line tester in the entire production process can eliminate the interference of human factors greatly improve the speed of production, thereby enhancing production efficiency. Some of the SMT production line from the traditional single online production to the dual-line mode of production, reduce floor space at the same time, improve production efficiency. Control efficiency, including the optimization of conversion and process control and optimization of management, control the way from the traditional step-by-step control of the way toward a focus on online optimization control the direction of the wire calculator to manage the entire production line of SMT equipment, as shown in Figure indicated that the production pcb board conversion time is getting shorter. At present, many foreign enterprises in the use of production management software to implement a centralized online control management of the entire SMT production lines, monitoring, statistical process parameters on the production of various equipment to ensure that each machine in the normal conditions to significantly improve the management efficiency of the production line and production efficiency for pcb manufacture and assembly.
