Delivering ultra-low loss RF substrates, hybrid lamination assemblies, and advanced HDI prototype circuits tailored for Aerospace, 5G Infrastructure, and Defense Sectors across France.
Our optimized Rogers PCB configurations and specialized controller motherboards currently serving defense & aerospace industries in France.
As France positions itself at the core of the European aerospace, defense, and telecommunications renaissance, the local demand for advanced sub-10GHz and millimeter-wave (mmWave) circuit solutions has scaled exponentially. Regions like Toulouse (the aerospace nexus), Paris-Saclay (the innovation cluster), and Sophia Antipolis (the electronics park) are driving rapid iteration cycles for radar, satellite communication payloads, and 5G/6G systems.
Under these stringent operating envelopes, standard FR4 substrates fail due to their high dissipation factor (Df) and fluctuating dielectric constant (Dk) at high frequencies. This has made Rogers high-frequency laminates the industry-standard choice. For French companies integrating RF systems into civilian or military projects, procuring Rogers PCBs requires working with a certified factory that adheres strictly to precise physical and chemical manufacturing specifications.
We work directly as an advanced engineering manufacturer, serving French companies by supplying custom Rogers 4000, Rogers 3000, and RT/duroid series laminate designs that satisfy complex environmental conditions and high electromagnetic requirements.
Understanding the structural differences in Rogers laminate chemistry to optimize performance, thermal limits, and cost structure.

|---|---|---|---|---|
| Rogers RO4003C | 3.38 ± 0.05 | 0.0027 | X: 11, Y: 14, Z: 46 | Automotive radar, LNBs, base station antennas, RF power amplifiers. |
| Rogers RO4350B | 3.48 ± 0.05 | 0.0037 | X: 11, Y: 14, Z: 50 | P2P microwave links, telecom infrastructure, satellite receivers. |
| Rogers RO3003 | 3.00 ± 0.04 | 0.0010 | X: 17, Y: 16, Z: 25 | 77GHz Automotive radar (ADAS), mmWave systems, satellite communications. |
| RT/duroid 5880 | 2.20 ± 0.02 | 0.0009 | X: 31, Y: 48, Z: 237 | Military aviation systems, radar systems, microstrip circuits, space flight payloads. |
Matching the coefficient of thermal expansion (CTE) of high-frequency Rogers substrates to active silicon components reduces shear stress during thermal cycling, critical for avionics platforms in French aerospace networks.
To optimize production costs, we combine Rogers layers (for RF signal paths) with standard FR4 inner/outer layers. This hybrid stackup delivers high-frequency performance at a lower cost.
Through precise laser drilling, deep control blind vias, and plasma desmearing, we guarantee trace impedance variances are kept below ±5% for stable signal transmission.

High-frequency Rogers PCBs operating in server and radar processing frames require matched thermal cooling and memory controllers to prevent system throttling.
Developing high-reliability PCBs based on Rogers substrates involves addressing manufacturing challenges that differ from standard FR-4 production. Surface finish chemistry, copper profile options, and mechanical edge milling must be customized to prevent micro-cracks and signal reflection.
For high-frequency applications, we offer ENIG (Electroless Nickel Immersion Gold) and ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold). These processes prevent copper oxidation while maintaining wire-bondability and smooth skin-effect paths. We also provide Immersion Silver for cost-sensitive projects requiring minimal signal insertion loss.
As frequencies scale past 10GHz, copper surface roughness influences insertion loss via the "skin effect." We source Rogers laminates with Rolled Annealed (RA) copper or Reverse Treated (RT) copper foil to maintain smooth conductor walls, minimizing signal attenuation for French space telemetry applications.
Our production facilities maintain high-precision tolerances for Rogers laminates:
Our engineering team can assist you in calculating track configurations, dielectric height, and hybrid lamination balances to prevent board warping.

Technical answers to common engineering questions regarding the manufacture, assembly, and sourcing of high-frequency Rogers PCBs.
Rogers materials offer a stable dielectric constant (Dk) and a low dissipation factor (Df) across a wide frequency range. Standard FR4 exhibits rising dielectric loss and shifting Dk at higher frequencies, causing signal degradation and phase distortion in microwave and millimeter-wave designs.
Hybrid stackups place high-cost Rogers materials only on layers where critical RF pathways run. The remaining layers utilize standard FR4. This technique reduces overall material cost while maintaining signal integrity, mechanical strength, and thermal resistance.
We maintain a stock of standard Rogers laminates, including RO4003C and RO4350B. Double-sided prototypes can be fabricated within 3 to 5 business days, while multi-layer hybrid production runs usually ship within 7 to 12 business days, with express air cargo options to France.
Trace width, trace thickness, and dielectric height are controlled during processing. We verify these parameters using automated impedance test coupons (TDR) to confirm trace tolerances remain within ±5% of the specified design value.
Yes, all components, base laminates, surface treatments (such as lead-free ENIG or Immersion Silver), and solder pastes meet EU RoHS requirements. Quality control records can be provided for compliance tracking.
