Directly integrated systems engineered for power electronics, specialized server setups, and high-frequency French automotive network architectures.
The industrial landscape in France is currently undergoing a massive structural transformation, driven primarily by the *France 2030* national investment plan. Decarbonization, heavy electrification of automotive platforms, high-speed rail network updates (SNCF/TGV), and the expansion of renewable energy generation facilities in Occitanie and Grand Est are creating unprecedented demands for highly specialized power electronics components. Among these, Thick Copper Printed Circuit Boards (PCBs) have emerged as a critical foundational component.
Thick copper PCBs, typically defined as boards with copper weights ranging from 3 oz/ft² to over 20 oz/ft² (heavy copper to extreme heavy copper), are indispensable in scenarios demanding massive current transmission and superior thermal regulation. Standard PCBs, which rely on 1 oz/ft² copper foil layers, fail under the thermal stresses induced by power converters, charging stations, and grid transmission lines. By utilizing thicker copper layers, engineers in French aerospace clusters (Toulouse) and automotive engineering parks (Lyon) can design systems with minimized footprints that resist thermal runaway under harsh operational configurations.
High-Power EV Charging Hubs (Bornes de recharge IRVE), Renewable Photovoltaic Inverters, Aerospace Auxiliary Power Units (APUs), and Automated High-Speed Railway Signal Units.
As a leading exporter, our facility bridges the gap between sophisticated raw design requirements and high-volume, reliable Chinese manufacturing lines. We specialize in producing thick copper boards designed specifically to withstand the stringent electrical regulations enforced throughout the European Union.
Engineered with 3oz to 20oz copper foils, enabling high-current distribution and low internal impedance for heavy duty French industrial machinery.
Unmatched heat dissipation capacity. Effectively handles continuous thermal shock test profiles conforming to European aerospace criteria (IPC-6012 Class 3).
Our facility guarantees zero-defect deliveries to French buyers through a combination of automated optical inspection (AOI) and burn-in reliability testing.
These high-performance hardware components support thick copper installations in heavy industrial computing hubs throughout metropolitan Paris and Marseille.
Navigating the global procurement framework requires more than just searching for low unit rates. In the precision electronics manufacturing sector, French buyers require compliance with strict regulatory regimes including RoHS, REACH, CE marking, and WEEE directives. By partner-shipping with NexaRAM Storage Technology Co., Ltd. (operating advanced production setups), global organizations access specialized industrial advantages:
With an annual export volume reaching $12 million USD and six years of dedicated European export experience, our systems are optimized to ensure smooth logistics flows through key French shipping hubs including Le Havre, Marseille-Fos, and Paris Charles de Gaulle.
Understanding the mechanical and electrical variables required to implement heavy copper substrates successfully.
As copper thickness increases, trace spacing and width rules must adapt. Standard etched patterns require wider spacing for 6oz copper than for 1oz. Our engineering team assists you in adapting your Gerber layouts to prevent shorts and achieve reliable etching yields.
By coupling heavy surface traces with thick-walled copper filled vias, heat is directly routed away from vulnerable silicon substrates down to integrated thermal management components, avoiding localized component failure.
For complex logic-meets-power designs, we utilize selective heavy copper deposition. This allows thin copper structures for signal traces and heavy copper sections for power transmission zones on the same board, reducing total system weight and complexity.

While standard PCBs utilize trace layers with copper weights ranging from 0.5 oz/ft² to 1 oz/ft² (17.5 µm to 35 µm thickness), "thick copper" boards employ trace configurations ranging from 3 oz/ft² to over 20 oz/ft² (105 µm to 700 µm thickness). These thick layers allow the boards to carry significantly higher electrical current and act as an integrated heat sink, eliminating the need for bulky external thermal components.
We utilize advanced Vertical Continuous Plating (VCP) lines that continuously monitor and adjust the electroplating current density. Following fabrication, we use automated optical inspection (AOI) alongside micro-section analysis to confirm that all trace profiles meet the IPC-6012 Class 3 performance criteria required for high-reliability systems in Europe.
Yes, through our selective heavy copper plating process, we can deposit heavy copper (e.g., 6 oz) on dedicated power distribution channels while maintaining standard copper weights (e.g., 1 oz) for high-density signal tracks elsewhere on the same layer. This reduces the number of boards required and simplifies your overall system architecture.
To resist the mechanical stresses caused by CTE (Coefficient of Thermal Expansion) mismatches under heat, we primarily use high-Tg FR-4 laminates (Tg 170°C to 180°C and above) from premium manufacturers like Shengyi and Isola. For extreme thermal profiles, we also manufacture Polyimide (PI) substrates and Metal Clad (IMS) boards.
We offer DDP (Delivered Duty Paid) and CIF/FOB logistics solutions through our experienced European shipping partners. We manage all export documentation, tariff classification, and customs clearance procedures for import through major hubs such as Paris Charles de Gaulle and Marseille-Fos, ensuring a seamless procurement process.
Our production facilities operate under ISO 9001:2015 and IATF 16949:2016 (Automotive Quality Management Standard) quality systems. All components comply with RoHS and REACH standards to meet European environmental regulations.
