Why is DFM Software Becoming Inevitable for PCB Manufacturability Analysis

Time:2022-01-24Views:179

In the context of intelligent manufacturing, intelligent tools are becoming a necessary aid for PCB manufacturability analysis. From the earliest human inspection to the intelligent software-aided, technological innovation has not only promoted the efficiency, but also facilitated the development and improvement of the entire manufacturing industry.

Conventional Manufacturability Analysis in PCB Design&Manufacturing

It might be rarely known by people that magnifying glass was ever used for PCB inspection. It could even be regarded as the first DFM (Design for manufacturing) tool of PCB (Printed Circuit Board) industry. In the 1990s, magnifying glass was used to inspect PCB Gerber to ensure the manufacturability of PCB. At that time, manufacturers decided whether to reject or accept the order by checking if the size like wire width, wire space and width of welded ring, which is obtained manually, exceeded their manufacturing capability.

It cannot be denied that manual DFM inspection was appropriate for the technology at that moment. Compared with the current PCB manufacturing technology and process design, the PCB at the time was designed with larger wire space and wire width, and the PCB design then was relatively simple. That’s why manual inspection survived that time.

However, as the PCB manufacturing industry and technology develops, the conventional DFM (design for manufacturing) approach of PCB is facing great challenge.

Innovative DFM Software Tools

Nowadays, as the PCB board is becoming smaller and thinner in size, the PCB design is becoming more complicated as well, which has brought up higher requirements on the capability of DFM analysis approaches.

Under such background, DFM software is emerging in response to the times and technology transformation.

Compared with the conventional DFM analysis approaches, this new DFM analysis tools is more intelligent and able to do more. DFM software tool could not only perform more comprehensive DFM/DFA analysis, but also satisfy the needs of DFM analysis in each process of NPI, such as design, assembly, prototyping, and fabrication, etc. If you are a product design engineer, you could use the DFM software to refine your design, making your design meet both internal and industry standards, what’s more, meet the manufacturing capability; if you are an EMS provider, you could use the DFM software, based on the process of production line, to evaluate the manufacturability, thus ensuring on-time delivery.

From a microscopic perspective, DFM software could fulfill the reading and transmission of multiple data, which could streamline the NPI (New Product Introduction) process and reduce the errors. For instance, VayoPro-DFM Expert software, developed by Vayo Technology, supports input of all CAD data types, such as Altium, Cadence, Mentor, Zuken, GenCAD, IPC-2581/ODB++, etc., and xy centroid data + Gerber data source. It also supports BOM data in TXT and Excel format when importing and validating BOM data; besides, the software is able to intelligently process the BOM data and assign suitable patterns on user’s demand.

Above all, DFM software tools has made the DFM analysis a more relaxing and time-saving work. For example, Vayo Technology’s VayoPro-DFM Expert software provides 2D/3D views, which can intuitively present the actual situation of PCBA and analyze potential manufacturability and reliability risks. After the DFM software automatically runs the analysis of manufacturability, it allows query and verification of each defect with 2D and 3D view interaction, besides, users are allowed to add notes, take 3D or 2D screenshots, and even get a comprehensive and intuitive 3D DFM analysis report in just a few minutes.

The industry history and technology development have proved that DFM software is indispensable for manufacturability analysis of PCB design.

Some reasons for you to apply DFM software:

– Intelligent DFM software could fulfill the design inspection of more complicated PCB.

– The function of identifying formats of file could facilitate the intelligent data transmission.

– The DFM software could fulfill the DFM analysis of each process from design to manufacturing.

– DFM software, as an important technology of concurrent engineering, could greatly reduce the prototyping times and shorten NPI cycle;

– To promote manufacturing quality and product reliability;

– To reduce cost and post-sales maintenance rate;

– 3D DFM/DFA report shows advanced DFM/DFA capability, thus promoting competitiveness.

– The intuitive report could greatly improve the communication effectiveness between customer/ R&D department and manufacturers.

Under the goal of making better products with lower cost, design for manufacturability of PCB has become an essential process of NPI. Hopefully, the DFM software tool will make this process more intelligent and efficient.
