Application of CIMS in SMT Chip Processing

ApplICation of CIMS in SMT Chip Processing
For many electronic companies using SMT equipment, the introduction of computer integrated manufacturing system cims into SMT chip processing production has improved product quality and the effective utilization of equipment, and greatly shortened the product design cycle and time to MARKet The economic benefits brought by CIMS to enterprises are obvious It is believed that the application of cims in enterprises SMT chip processing will become more and more widespread in the near future
Application of cims in enterprises SMT chip processing and production
Many equipment in SMT chip processing production line are computer controlLED automatic processing equipment, which makes it possible for computer aided manufacturing to form a CAD/CAM integrated system.

Almost all the design departments of modern electronic manufacturing companies use cad software for circuit design, and the manufacturing departments also use a large number of automation equipment for production, such as chip mounters, DIP processing plug-in programmers, etc., but these two departments rarely understand each other's needs, and many useful information cannot be shared. Enterprises often form two "automation" islands. With the intensification of market competition, customers require to shorten product delivery cycle and control production costs. It is urgent to establish a connection between the two islands to shorten the production preparation time, strengthen the defect analysis before production, and reduce product rework. In order to connect the "automation island" of CAD design system and the information flow between production automation, and eliminate the "partition" between product design and product manufacturing, only computer integrated manufacturing system (CIMS) can be used. complete
Handle CAD design files, improve assembly accuracy, and greatly reduce failure rate.
In the 1970s, Dr Joseph Harrington first proposed the concept of cim (computer integrated manufacturing).  Its connotation is to integrate various scientific and technological systems related to manufacturing in enterprises with the help of computers, so as to improve enterprises' ability to adapt to market competition However, cims, a system based on the concept of CIM, began to be valued and implemented on a large scale in the mid 1980s Cims is based on database, and transmits the data in the design environment to various automatic processing equipment through computer network, and can effectively control and supervise these automatic equipment The connection between the production department and the design department is established by using cims, which can be realized by cad integration As mentioned earlier, many of the equipment in SMT chip processing production lines are computer controlled automatic processing equipment, which provides a completely possible/cam integrated system for computer-aided manufacturing to form cad In fact, most of the data required for the programming of processing equipment in the SMT SMT production line can be obtained from the relevant data files of the CAD system For example, coordinate position, angle, physical parameters, electrical parameters, etc PCBA upper assembly These data volumes are very large, and different processing equipment need some characteristic data For example, placement machine, distributor and online test equipment all need the coordinate position of components on PCB Therefore, the idea and technology of CIMS are used to establish a cad system/cad and cam integrated system, directly select, organize/transform and optimize the corresponding characteristic data in the cad system data file, and program the data format requirements according to the specific equipment or n format. The/c command needs to be transmitted to the control computer of the processing equipment through the computer network and interface communication software, so as to directly call or directly drive the numerical control processing equipment during the programming But also because of the direct
Due to the characteristics of the production of the SMT industry, it is more appropriate to use just in time system for on-site management The combination of just in time and total quality control can reduce waste and improve product quality
