What is DFM in PCBA design? The role of DFM in the design of PCBA.
What is DFM
Design for manufacturability of products is called DFM for short. It is a discipline that studies some design behavior rules of the relationship between the physical design of the product itself and various parts of the manufacturing system, and applies them to product design so as to integrate the whole manufacturing system for overall optimization.
As we all know, the design phase determines 80% of the manufacturing cost of the product. Similarly, many quality characteristics are fixed at the time of design. Therefore, it is very important to fully consider the manufacturing factors in the design process.
The Role of DFM in the Design of PCBA
Good DFM is an important link for product manufacturers to reduce manufacturing defects, simplify manufacturing process, shorten manufacturing cycle, 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 the effect of twice the result with half the effort.
A large number of successful PCBA design examples show that the dual purposes of "zero defect design" and "zero defect manufacturing" can only be achieved if the manufacturability, usability, detectability, manufacturing economy, quality stability, etc. of PCBA are fully demonstrated and paid attention to at the initial stage of design and implemented in the whole process of design and manufacturing.
Today, the development of surface mount parts requires our PCBA designers not only to be proficient in design technology, but also to have a deep understanding of the process of PCBA manufacturing. Because a designer who does not understand the flow characteristics of solder paste and solder, it is difficult to understand the causes and mechanisms of bridging, pointing, tombstone, core suction and other phenomena, and it is also difficult to work hard to reasonably design pad graphics, and it is difficult to deal with various design problems from the perspective of design manufacturability, detectability, and cost reduction. Imagine a scheme with perfect design in other aspects, but DFM is poor, which will cost a lot of manufacturing and testing costs. Even if this product can be manufactured, what is its market competitiveness?
In industrial production, product quality problems caused by imperfect DFM or limitations of products are characterized by batch production, which is difficult to solve and compensate in production. This is the truth of the old saying that "congenital deficiencies are difficult to compensate".
