Understand the distribution of CIMS and SMT
The computer integrated manufacturing system cims is introduced into SMT chip processing and production, which improves the product quality and the effective utilization of equipment, and greatly shortens the design cycle and time to market of PCB products The economic benefits brought by CIMS to enterprises are obvious It is believed that in the near future, cims will be more and more widely used in SMT chip processing and production
Application of cims in SMT wafer processing
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. The only way to connect the information flow in the "automation island" of CAD design system and production automation, and eliminate the "partition" between PCB product design and product manufacturing, is to realize it through the computer integrated manufacturing system (cims).
Handle CAD design files, improve assembly accuracy, and greatly reduce failure rate.
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 equipment in the SMT chip processing production line 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 The amount of PCB data is very large, and different processing equipment needs some characteristic data For example, PCB placement machines, glue dispensers, and online test equipment all need the coordinate positions 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 This not only saves data preparation and programming time, but also
Due to the production characteristics of smt industry, it is more suitable to use jit for on-site management. The combination of jit and tqc can reduce waste and improve product quality.
