Pogo Pin Connector DFM Report Production Training
A DFM report refers to a design-for-manufacturing report. The DFM process is actually a process of technical negotiation with customers, which reflects the comprehensive quality of an excellent design. The result is directly related to the quality and cost of the mold. It is no exaggeration to say that a good negotiation result not only saves costs for the company and improves product quality, but also helps customers reduce costs. It's a win-win job. The level of the DFM report directly reflects the skill of the designer, determines the quality and cost of the product, and reflects the technical strength of the enterprise.
DFM means to design for manufacturing, Design for manufacturability, that is, starting from improving the manufacturability of parts, making parts and various processes easy to manufacture, low manufacturing cost, high efficiency, and low-cost ratio.
Manufacturing-oriented design means that the product design needs to meet the requirements of product manufacturing and has good manufacturability so that the product can be manufactured with the lowest cost, the shortest time, and the highest quality. According to different product manufacturing processes, manufacturing-oriented design can be divided into injection-oriented design, stamping-oriented design, and die-casting-oriented design.
Today's DFM is the core technology of concurrent engineering, because design and manufacturing are the two most important links in the product life cycle, and concurrent engineering is to consider factors such as product manufacturability and assembly at the beginning of design.
So DFM is the most important support tool in concurrent engineering. Its key is the process analysis of design information, the evaluation of manufacturing rationality, and the suggestion for improving the design.
DFM mainly studies the relationship between the physical design of the product itself and the various parts of the manufacturing system and uses it in product design to integrate the entire manufacturing system for overall optimization. It is the most effective method to ensure the quality of PCB design.
DFM is to consider manufacturability from the time of product development and design, so as to make a close connection between design and manufacturing and achieve the purpose of a successful one from design to manufacturing.
The advantages of DFM and its important role：
1. Reduce costs and improve product competitiveness
Low cost and high output are the eternal pursuits of all companies. By implementing the DFM specification, the company's resources can be effectively utilized, and products can be manufactured with low cost, high quality, and high efficiency. If the design of the product does not conform to the company's production characteristics and the manufacturability is poor, it will take more human, material, and financial resources to achieve the goal. At the same time, it has to pay a heavy price of delaying the delivery and even losing the market.
2. Optimize the production process and improve production efficiency
DFM organically links the design department and the production department to achieve the purpose of information exchange, so that the design development and production preparation can be coordinated. Unified standard, easy to realize automation, improve production efficiency. At the same time, the standardization of production test equipment can be realized, and the repeated investment of production test equipment can be reduced.
3. Facilitate technology transfer and strengthen company collaboration
At present, many enterprises are limited by the production scale, and a lot of work needs to be carried out by external processing. By implementing DFM, the manufacturing technology can be smoothly transferred between the processing unit and the processing unit, and production can be organized quickly. The versatility of design for manufacturability enables enterprise products to be produced globally.
4. The basis for new product development and testing
There is no proper DFM specification to control the design of the product, and assembly problems of one kind or another are only discovered at the later stage of product development, or even in the mass production stage. At this time, trying to correct through design changes will undoubtedly increase development costs and prolong product production. cycle. Therefore, in addition to focusing on function first, DFM is also very important for new product development.
5. Suitable for a new technology of electronic assembly process
Now, the development of new electronic assembly technology is becoming more and more complicated. In order to seize the market and reduce costs, the company must use the latest and fastest assembly technology and standardize DFM to keep up with its development.
