Vayo 3D Evolving DFM

Pure 3D DFM Solution
3D Evolving DFM

Vayo DFM is an intelligent PCB DFM, PCBA manufacturability analysis software, and DFMA solution for design and process engineering teams. It enables full-process DFM software and DFMA analysis across PCB assembly, including solder paste printing, SMT placement, reflow soldering, through-hole insertion, wave soldering, testing, and AOI inspection.

With a comprehensive 3D component library, the system simulates the PCB assembly process and performs automated manufacturability checks based on digital DFM rules, enabling accurate design validation before production and improving manufacturing reliability.

Unlike traditional DFM tools, Vayo DFM evolves into a continuous digital engineering system. Manufacturing experience and process knowledge are captured and converted into reusable rules, forming a closed-loop DFMA and DFM improvement cycle between design and manufacturing, continuously enhancing product quality and yield.

Industry Pain Points: Four Major Challenges in Electronic Design & Manufacturing

Electronic modules are core components in products from communications to defense. PCB/PCBA design and manufacturing face major challenges driven by human factors:

From Static Rules to Evolving DFM Know-how

The Status Quo: Lost Experience
Traditional DFM automation relies on static rule libraries. Converting new manufacturing issues and lessons learned into reusable rules is complex and slow. Valuable engineering experience is often lost with every product lifecycle.

The Vayo Way: Evolving DFM
Vayo enables a code-free digital upgrade. It captures insights from design, production, and after-sales service, instantly transforming them into active DFM rules in just 5 minutes. Build an evolving engineering knowledge base that eliminates recurring defects and accelerates high-yield product launches.

Pure 3D DFM Solution

To overcome the limitations of traditional DFM, Vayo introduces a Pure 3D Evolving DFM solution. Built on a pure 3D architecture and no-code rule engine, the software supports comprehensive manufacturability analysis, including footprint validation, component placement, PCB routing, test point inspection, and PCBA reliability review.

The software continuously evolves by converting real engineering experience from design, manufacturing, and after-sales processes into reusable digital assets and a living knowledge base.

Comprehensive Manufacturability Analysis

Built on over 20 years of industry expertise, Vayo DFM software delivers comprehensive PCB DFM and PCBA DFMA (Design for Manufacturability & Assembly) inspection capabilities across the full design-to-manufacturing lifecycle. It supports IPC standards, enabling both prototype and mass production validation, helping manufacturers identify risks early, improve yield, and optimize production efficiency.

The system provides multi-dimensional analysis, including:
√ PCBA assembly checks (PIP, wave soldering, selective soldering, press-fit, placement and footprint review)
√ PCB fabrication verification (routing, inner layers, silkscreen, solder mask, drilling and via analysis)
√ Design integrity checks such as netlist open/short detection and design omission review

Advantage: Continuous Evolution Without Coding

Unlike traditional DFM systems with fixed rule libraries, Vayo DFM enables companies to create and expand review rules independently through a no-code architecture. Engineers can build new rules in minutes without programming skills.

Manufacturing improvements, field failures, and design optimization experience can all be converted into digital review rules, allowing engineering knowledge to grow continuously as a long-term digital asset.

This helps companies standardize knowledge sharing, reduce dependency on experts, and shorten engineer training cycles.

Advantage: Pure 3D Technology

As the industry’s first 3D PCB/PCBA DFM solution, Vayo DFM delivers enhanced pure 3D capabilities. Based on IPC standards, the software builds intelligent 3D component models including package type, dimensions, pin definitions, and orientation. STEP models can also be imported for complex components.

In a pure 3D environment, engineers can visually evaluate pin-to-pad matching, assembly risks, and manufacturability impacts more intuitively. The software also supports seamless 2D/3D interactive viewing.

3D DFM reports can be exported in Word or Excel formats, while lightweight 3D models can be transferred to mainstream MCAD platforms including CATIA, Creo, SolidWorks, and NX.

Digital DFA Assembly Analysis

Traditional DFM mainly focuses on PCB-level analysis and often overlooks system-level assembly risks involving enclosures, cables, and fasteners. These issues are frequently discovered only during assembly.

Vayo extends DFM (Design for Manufacturability) into DFA (Design for Assembly) by integrating structural parts, cables, fasteners, and enclosures into a complete digital prototype. Automated analysis identifies assembly interference, connector alignment risks, and other reliability concerns before production.

Platform-Based DFM Solution

Vayo DFM can be upgraded into a platform-level DFX solution (Vayo DFX Execution System), delivering lightweight, end-to-end PCB and PCBA DFX (Design for Excellence) analysis across the entire product development lifecycle.

The platform supports DFM, DFA, DFT, DFR, EMC, and Netlist verification, with 24/7 automated execution and seamless integration with mainstream EDA tools. This enables a closed-loop design-to-manufacturing quality control system, helping manufacturers improve PCB design quality, reduce manufacturing risks, and accelerate time to production.

Proven Business Impact: Accelerating Digital Transformation in Design & Manufacturing

Vayo DFM software enables enterprises to digitalize and preserve engineering know-how, continuously accumulate manufacturing expertise, and automate design rule verification. This helps eliminate quality fluctuations, optimize design-to-manufacturing processes, and establish end-to-end quality assurance from design initiation to mass production delivery.
