Product design for manufacturability is referred to as DFM. It is the study of some design behavior rules of the relationship between the physical design of the product itself and the various parts of the manufacturing system, and it is used in product design to integrate the entire manufacturing system for overall optimization.

As we all know, the design stage determines 70%-80% of the manufacturing cost of the product. Similarly, many quality characteristics are also fixed during the design. Therefore, it is very important to fully consider the manufacturing factors during the design process.

Good DFM is an important link for product manufacturers to reduce manufacturing defects, simplify manufacturing processes, shorten manufacturing cycles, reduce manufacturing costs, optimize quality control, enhance product market competitiveness, and improve product reliability and durability. It can enable enterprises to obtain the best benefits with the least investment and achieve a multiplier effect with half the effort.

The most important thing for SMT chip processing circuit board products is product reliability. Reliability is the basis of SMT chip processing and production. Reliability is an important indicator of circuit board products. In the past, reliability was neglected. When the car is running, the circuit board wires transfer to each other, increasing heat energy. If the product does not consider safety and the circuit board fails during operation and causes a car accident, then the problem will come. Is the reliability setting of the circuit board important?

The answer is yes, the purpose of reliability design is to achieve the required reliability at the least cost.

Reliability is an important indicator of electronic products. Product reliability not only affects the future of SMT chip processing and production enterprises, but also directly affects the value of the product. Especially for military communication equipment, it has special significance.

The reliability design of the printed circuit board is very complicated, and the content of the reliability design is many, such as thermal design, drift design, anti-interference design, protection circuit design (anti-vibration design, three-proof design), SMT process design, safety design, man-machine System design, reliability review and value analysis, reliability experiment and reliability evaluation, etc.

Therefore, for high-end electronic products, for safety and product value, SMT circuit board manufacturers need to design circuit boards for reliability.

The above is the introduction of what is the DFM of the printed circuit board. I hope it can help you. At the same time, if you want to know more about the information of the printed circuit board, you can pay attention to the update of KFPCBA.
