State-of-the-art printed circuit boards and memory systems tailored for industrial automation, network infrastructure, and smart IoT assembly in Bac Ninh, Binh Duong, and Ho Chi Minh City.
Vietnam has consolidated its status as a premier global hub for electronics manufacturing and system integration. Driven by massive capital inflows in key economic zones such as Bac Ninh, Bac Giang, Hai Phong in the north, and Binh Duong and Dong Nai in the south, the country’s demand for high-reliability Printed Circuit Board Assemblies (PCBAs) and industrial-grade memory modules has grown exponentially. As global technology giants establish massive SMT lines and device assembly centers in Vietnam, local OEMs require agile supply chains that offer high-precision engineering, raw materials resilience, and specialized hardware configurations.
Operating in this tropical environment presents unique challenges for electronic engineering. Extreme humidity and high ambient temperatures demand advanced PCB surface finishes, precise conformal coatings, and high-performance glass-transition temperature (Tg) substrates to avoid delamination and electrochemical migration. In partnership with Chinese supply chains, Vietnamese manufacturers can secure specialized boards—ranging from double-sided FR4 matrices to complex high-density interconnect (HDI) multilayers—that maintain continuous performance in demanding industrial and telecommunication environments.
Supply Chain Insight: Leveraging Shenzhen's advanced PCB fab capabilities combined with direct logistics corridors to Vietnam (via Pingxiang-Lạng Sơn or direct shipping routes to Hai Phong Port) allows Vietnamese assemblers to reduce lead times to under 7 days, maintaining zero-inventory buffer models without risking line downtime.
Corexis Memory Technology Co., Ltd. (established in 2016) operates at the intersection of high-speed semiconductor testing and complex custom PCBA manufacturing. With a cleanroom production facility spanning 21,800 square meters, we deliver industrial-grade DRAM solutions and complex multi-layer PCB designs to global system integrators and OEMs.
Our operation is built on precise engineering and automated quality control, supporting both high-mix low-volume prototyping and mass-market consumer electronics assembly. With 128 dedicated R&D engineers, we customize hardware solutions from the board layout level up to high-speed memory interfaces (including DDR4 and DDR5 topologies), ensuring compatibility with localized hardware setups in Vietnam's industrial corridors.
Our quality assurance processes rely on modern inspection technologies, including Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Final Quality Control (FQC), and Outgoing Quality Assurance (OQA). With 56 specialized QC inspectors, every production batch goes through Automated Optical Inspection (AOI), X-ray thickness validation, and thermal cycling stress tests to ensure reliable performance on Vietnamese assembly lines.
The "China + 1" business strategy has transformed how modern electronics are developed. Instead of completely moving production away from China, top electronics brands use China's unmatched copper clad laminate (CCL) production, component inventory, and engineering services alongside Vietnam's cost-effective final product assembly.
As an integrated manufacturing partner, Corexis links raw material sourcing directly with localized assembly plants in Vietnam. We supply bare boards, semi-finished assemblies, and verified memory modules to Vietnamese factories, reducing reliance on long-distance components. This setup helps protect production lines from global shipping changes, tariff adjustments, and raw material shortages.
| Strategic Indicator | Guangdong-Shenzhen Cluster | Vietnam (Bac Ninh / HCMC Corridors) | Synergistic Benefit for OEMs |
|---|---|---|---|
| Raw Material Access | Immediate access to FR4, Taconic, Rogers, and raw copper laminates | Growing localized inventory, primarily reliant on imports | Shortened fabrication lead times through upfront material hedging |
| Prototyping & R&D | Fast-turn PCB prototypes in 24–48 hours | Focused on high-volume assembly and box-build projects | Rapid design validation in China before high-volume deployment in Vietnam |
| Logistics Timeline | Centralized shipping ports & air hubs | Overland transport connection from Southern China to Northern Vietnam | Reduced shipping times (3-5 days via overland trucking networks) |
| Quality Standards | ISO 9001, UL, RoHS, and REACH certified lines | Growing alignment with international compliance frameworks | Zero-defect components ready for immediate integration into global products |
As Vietnamese electronics manufacturers move from basic consumer assembly to producing high-value automotive radar systems, 5G base stations, and edge-computing devices, their technical needs are changing rapidly. Our production roadmap focuses on three main areas:
Utilizing high-performance Taconic TLY-5 and Rogers materials to support high-frequency microwave applications up to 77GHz, ensuring minimal signal attenuation for telecommunication and radar systems.
Implementing laser-drilled microvias, stacked vias, and thin-film polyimide FPC designs to enable compact layouts for medical wearables, smart keyboards, and IoT hardware.
Designing PCBs with tight impedance controls, balanced copper weights, and advanced EMI shielding to handle high data rates for DDR5 memory modules in server systems.
In addition to board fabrication, our SMT lines are optimized for lead-free solder paste configurations, matching the global shift toward green manufacturing. Surface finishes like Immersion Silver (ImAg), Immersion Tin, and Electroless Nickel Immersion Gold (ENIG) are carefully selected based on the specific assembly requirements of each project.

Technical information on our engineering capabilities, logistics, and quality assurance processes for our customers in Vietnam.
To prevent performance issues like copper corrosion and electrical shorts caused by high humidity, we offer specialized protective measures. These include thin-film conformal coatings (acrylic, polyurethane, or silicone coatings applied via automated spray machines) and high-quality surface finishes like Electroless Nickel Immersion Gold (ENIG) or Immersion Silver. These coatings protect vulnerable joints and fine-pitch components from moisture.
Standard prototype boards (up to 4 layers) can be manufactured in 3–5 working days. High-volume SMT and PCBA production runs typically take 2–3 weeks, depending on component availability. For shipping, we use land routes from southern China to northern Vietnam (such as Bac Ninh or Lang Son) which take 3–5 days. We also ship via airfreight to Hanoi (HAN) or Ho Chi Minh City (SGN) in 1–2 days, or by sea to Hai Phong Port in 5–7 days.
Yes. Corexis offers complete OEM and ODM design services. We can customize trace routing, copper thickness, heat-spreader designs, and memory configurations (like ECC or non-ECC DDR4/DDR5) to match the requirements of your industrial hardware.
Our quality control system ensures full traceability from raw materials to finished products. We scan unique barcodes at each production step: material incoming inspection (IQC), paste deposition, SMT component pick-and-place, reflow soldering, and automated optical inspection (AOI). For critical components like DRAM chips, we maintain batch records linked to test logs, making it simple to isolate and analyze any failures.
Yes, all our PCBs and SMT assemblies meet international environmental standards. We offer Lead-Free Hot Air Solder Leveling (HASL Lead-Free), ENIG, and OSP surface finishes, ensuring our products comply with RoHS and REACH regulations for import into Europe, North America, and other regulated markets.
