Series III of “2025 China Semiconductor Go-Global Study Tour: Vietnam Edition”
This article is part of the original “2025 China Semiconductor Go-Global Study Tour: Vietnam Edition” series, jointly curated by the Yeehai Global Institute and the China Exportsemi. The series focuses on Vietnam's most representative EMS (Electronics Manufacturing Services) providers, offering firsthand insights to support Chinese semiconductor companies in identifying high-quality overseas partners.
I. TNEMS: An Emerging Powerhouse in Central Vietnam
Vietnam’s electronics manufacturing industry has traditionally been concentrated in the north (e.g., Hanoi, Bac Ninh) and the south (e.g., Ho Chi Minh City and its industrial zones). However, Trungnam Electronics Manufacturing Services (TNEMS), located in Da Nang—the heart of central Vietnam—is quickly rising as a formidable new player, backed by group-level resources, high-end technological investments, and a strong commitment to green manufacturing.
1. From Trungnam Group to High-End Manufacturing
TNEMS is the electronics manufacturing arm of Trungnam Group, one of Vietnam’s largest private conglomerates. Founded in 2004, Trungnam Group has established a strong presence across renewable energy, infrastructure, real estate, and telecommunications. Notably, the group’s 450MW solar power installations and 500kV transmission line projects have earned it a distinct reputation in the green energy sector.
Established in 2020, TNEMS marks the group’s strategic transformation from traditional industries into high-tech manufacturing. Its ambition goes beyond contract manufacturing; TNEMS aspires to become a global provider of electronics, IT, and semiconductor solutions.
2. Da Nang: A New Manufacturing Gateway in Central Vietnam
Da Nang, where TNEMS is headquartered, is a geographically central city connecting north and south Vietnam, with convenient access to inland and maritime routes. With a modern international airport, well-developed port infrastructure, and expressway links across the country, Da Nang is emerging as a key node in Vietnam’s national strategy.
For Chinese companies seeking stable and diversified supply chains, Da Nang offers not only a new industrial hub but also strategic advantages in geopolitical neutrality and operational safety.

II. Advanced Production Lines & One-Stop Capabilities
TNEMS currently operates four SMT (Surface Mount Technology) lines and two assembly lines, with an annual capacity of 7 million units. The lines are equipped with advanced equipment including YAMAHA mounters, AOI, SPI, and X-ray inspection systems, and support the entire production cycle—from prototyping and small-batch trial runs to full-scale mass production.
Its services include:
SMT and THT PCB assembly
Flying probe testing, wave soldering, selective soldering
Subassembly, system integration, product configuration, and packaging
Rapid prototyping and BOM matching services
OEM/ODM-compatible material management and sourcing
Compared to traditional EMS providers, TNEMS demonstrates stronger system integration capabilities, with proven expertise in complex PCBA assembly and system-level manufacturing.

III. MES 4.0 Integration and Smart Factory Vision
TNEMS has adopted a comprehensive MES 4.0 (Manufacturing Execution System) to enable real-time visibility and data-driven control across the entire production process. Customers can monitor each production stage, receive automated alerts, and access full traceability and quality feedback.
The company is also embracing Industry 4.0 principles—leveraging digital control, automated inspection, and process optimization—to steadily transition into a smart factory model.
IV. International Standards & Beyond-Industry Quality Commitment
TNEMS has achieved several international certifications, including:
ISO 9001:2015 (Quality Management)
ISO 14001:2015 (Environmental Management)
ISO 13485:2016 (Medical Devices)
IATF 16949:2016 (Automotive Electronics)
Its quality control emphasizes both in-process checks and final inspections, supported by functional, environmental, and automated testing systems. With a “zero-defect, zero-complaint” delivery target, TNEMS offers a reassuring level of quality assurance for Chinese clients outsourcing mid- to high-end products.
V. Green Factory Vision & Sustainability Commitment
TNEMS is notable for its sustainability-oriented infrastructure. Its Da Nang facility incorporates solar-powered rooftop systems, ISO 7-class cleanroom ESD protection, and eco-friendly design to minimize carbon emissions. The company integrates energy-saving principles into its production planning.
Such practices not only align with global ESG (Environmental, Social, Governance) priorities but are also likely to become key differentiators or even prerequisites in future business collaborations.
VI. Talent Strategy: Central Vietnam’s Workforce Advantage
Compared to the northern region, Central Vietnam offers a more stable labor pool with lower turnover rates. TNEMS benefits from its proximity to 36 universities and colleges in and around Da Nang, enabling it to recruit a steady stream of technical graduates. The company also partners with vocational institutions to build a local talent pipeline.
Its engineering and management teams are composed of experienced professionals who emphasize teamwork and responsiveness, ensuring fast and sustained project-level support for international clients.
VII. Expanding Global Partnerships
Though a relatively new entrant, TNEMS has already secured collaborations with companies and organizations such as YAMAHA, PREMO, GGEC, Bkav, JETRO, EUROCHAM, and VietinBank. Its customer base spans Japan, South Korea, Europe, the U.S., and local governments and financial institutions.
This reflects the company’s readiness to work alongside international brands in terms of technical capabilities, delivery quality, and service standards.
VIII. Observations: TNEMS – A Rising Star Worth Watching
As a featured company in the “2025 Vietnam Manufacturing Watch” series, TNEMS stands out for the following reasons:
Strong backing from a conglomerate with long-term industrial commitment
High-spec facility standards, sustainability-conscious operations, and modern equipment
Strategic central location with growing industrial potential and flexibility
Comprehensive services and digitalized manufacturing management
For Chinese companies in semiconductors, smart devices, and industrial modules seeking diversified manufacturing options, TNEMS may be a lesser-known name today—but it represents a valuable partnership window for the next five years.
Upcoming Event – “0621 Vietnam Tour”
Organized by Yeehai Global, the China Exportsemi will host the “0621 Vietnam Tour” from June 21–26, 2025, with on-site visits to EMS enterprises in Ho Chi Minh City, Bac Ninh, and other regions. Semiconductor companies interested in the Vietnamese EMS ecosystem are welcome to reserve seats or nominate outstanding manufacturers to join the delegation.
