Integrating state-of-the-art base materials with high-density interconnect (HDI) technology, these core platforms are designed to fulfill the rigorous signal integrity requirements of France’s modern telecom and edge computing nodes.
France has established itself as one of Europe’s primary centers for technology innovation. With industrial clusters such as Toulouse Aerospace Valley (home to Airbus and key Thales projects), Paris-Saclay (the premier research and development incubator), and the microelectronics research facilities in Grenoble, the demand for high-frequency, high-performance printed circuit boards has grown rapidly. Standard FR-4 laminates no longer suffice for advanced microwave, RF, and high-speed digital designs.
Rogers PCBs, utilizing specialty ceramic-filled PTFE or thermoset hydrocarbon laminates, are crucial for modern French technology initiatives. These boards deliver low dielectric loss, stable dielectric constants (Dk) across wide temperature ranges, and superior thermal dissipation, which are vital for aerospace communication links, automotive radar systems (77 GHz / 79 GHz), and high-frequency 5G/6G cellular infrastructure across France.
As a key supplier, we offer direct access to specialized Rogers laminates, customized hybrid stack-ups, and precision SMT capabilities. By bridging the gap between high-frequency substrates and commercial mass production, we help French engineering departments accelerate their transition from prototype design to full market deployment.
For French microwave engineers developing 5G base stations, satellite communication arrays, or high-definition radar, understanding material differences is essential. Below is a comprehensive comparison of standard FR-4 and popular Rogers laminates sourced for industrial clients in France:
| Material Series | Dielectric Constant (Dk @10GHz) | Dissipation Factor (Df @10GHz) | Thermal Conductivity (W/m/K) | Primary Industrial Applications |
|---|---|---|---|---|
| Standard FR-4 | 4.2 - 4.8 | 0.015 - 0.020 | 0.25 - 0.40 | General digital circuits, simple office PC motherboards. |
| Rogers RO4003C | 3.38 ± 0.05 | 0.0027 | 0.71 | RF base station antennas, LNBs, radar, high-speed backplanes. |
| Rogers RO4350B | 3.48 ± 0.05 | 0.0037 | 0.69 | Automotive radar, power amplifiers, satellite TV LNB, RF designs. |
| Rogers RT/duroid 5880 | 2.20 ± 0.02 | 0.0009 | 0.20 | Airborne radar systems, microstrip antennas, space applications. |
| Rogers RO3003 | 3.00 ± 0.04 | 0.0013 | 0.50 | 77 GHz automotive radar systems, ADAS, collision avoidance. |
Rogers substrates exhibit exceptionally low dissipation factors (Df), ensuring high-frequency signals suffer minimal attenuation across long routing paths. This is essential for French telecom networks operating at mmWave bands.
With glass transition temperatures (Tg) exceeding 280°C and a low coefficient of thermal expansion (CTE) matching copper, these PCBs resist warpage during assembly and maintain structural integrity under temperature fluctuations.

We provide comprehensive OEM, ODM, private label, logo printing, packaging customization, capacity customization, firmware optimization, and product specification customization to meet different market requirements.
French technology manufacturers must navigate complex regulatory and quality compliance standards. When purchasing custom Rogers PCBs or high-speed memory assemblies from Novram, compliance with EU regulations is fully managed:
All Rogers PCB laminates, solder pastes, and finish coatings (such as ENIG or ENEPIG) comply with European RoHS and REACH directives, ensuring environmental safety and hazard-free deployment in civil markets.
We provide full component traceability and manufacture high-frequency layouts in compliance with IPC-A-600/610 Class 3 specifications, meeting the reliability standards required by aerospace and defense contractors in France.
Our engineering team performs a Design for Manufacturability (DFM) check before production, verifying that impedance tolerances, copper weights, and layer stack-ups align with Rogers' fabrication limits.
We offer reliable door-to-door shipping solutions to major industrial zones throughout France, including Lyon, Toulouse, Grenoble, Paris, and Nantes. Working with partners like DHL, FedEx, and specialized European customs agents, we facilitate customs clearance to ensure prompt delivery of high-frequency materials and memory boards.
As computing architectures move toward PCIe Gen 6/7, DDR5 speeds above 6400MHz, and high-frequency communication bands, the integration of high-performance substrates and fast memory systems becomes increasingly important. Novram's R&D center is currently working on:
To optimize product costs for French telecom manufacturers, we design hybrid layer stack-ups. This approach places Rogers laminates on the critical RF/high-speed signal layer, while utilizing high-Tg FR-4 for power and general ground planes, reducing material costs without compromising high-speed performance.
Modern thermal envelopes in edge servers require efficient heat dissipation. By using Rogers materials (with high thermal conductivity) combined with micro-vias and thick copper plating, we enhance heat dissipation for heavy-load industrial motherboards and server computing blades.
For mmWave radar applications above 77 GHz, copper surface roughness significantly impacts conductor loss due to the skin effect. Novram offers Rolled Annealed (RA) and Reverse Treated (RT) copper options on Rogers laminates, ensuring clean signal pathways for automotive safety systems.
Our DDR5 modules utilize low-loss substrates and optimized layout routes to minimize crosstalk, supporting the high density and speed requirements of AI, machine learning, and enterprise computing platforms across Europe.
While high-speed FR-4 materials perform well up to a few gigahertz, Rogers laminates (such as RO4003C or RO4350B) offer significantly lower loss tangents and a more stable dielectric constant (Dk) across wide operating temperatures and frequencies. This minimizes signal attenuation and phase distortion, which is essential for RF and high-speed digital networks.
Yes, we specialize in fabricating hybrid multi-layer PCBs. This layout allows for high-frequency Rogers laminates on the outer signal layers and cost-effective FR-4 on the inner layers, providing high performance at a lower overall production cost.
We use precision Polar Instruments software to model and calculate trace structures. During fabrication, we run Time Domain Reflectometry (TDR) testing on specialized test coupons on the panels, ensuring that your target impedance tolerances (typically ±10%, or ±5% upon request) are met.
For RF applications, Electroless Nickel Immersion Gold (ENIG) or Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) is highly recommended. These finishes provide excellent surface flatness for component assembly and maintain good conductivity at high frequencies. Immersion Silver or OSP can also be used depending on your loss budget.
For quick-turn prototyping, shipping takes about 3 to 5 business days after manufacturing. For larger mass production runs, we coordinate air or sea logistics, handling export documentation to ensure delivery to locations like Toulouse, Grenoble, and Paris.
