Rogers PCB refers to printed circuit boards built with Rogers high-performance laminates (instead of conventional FR-4), designed for:
-
High-frequency / microwave circuits
-
High-speed and low-jitter digital transmission
-
High-reliability electronics that face thermal cycling, humidity, or harsh environments
Common Rogers Material Options
We can manufacture Rogers PCBs using commonly selected Rogers material families such as:
-
RO4000 Series: Glass-fiber reinforced, strong cost-performance for commercial high-frequency PCBs
-
RO3000 Series: Ceramic-filled, very low loss for millimeter-wave applications
-
RT/duroid Series: PTFE-based ultra-low loss substrates for advanced RF designs
-
TMM Series: High thermal conductivity + low loss + high thermal stability, built for high-performance needs
(Final selection depends on frequency band, loss target, stackup, and fabrication constraints.
Key Advantages
1) Excellent Electrical Performance
-
Stable Dielectric Constant (Dk): Minimal Dk variation across frequency and temperature helps maintain impedance and phase stability, especially in RF and high-frequency circuits.
-
Extremely Low Dielectric Loss (Df): Lower loss than FR-4 reduces signal attenuation and improves high-frequency signal integrity, particularly in higher GHz ranges.
-
Low Surface Roughness Options: Smoother copper foil surfaces help reduce conductor loss caused by skin effect, which becomes more important at millimeter-wave frequencies.
2) Thermal Stability & Reliability
-
Low CTE (Coefficient of Thermal Expansion): Better CTE matching (especially with copper) reduces risk of via / hole wall stress during temperature cycling—important for multilayer reliability.
-
High Tg Options: Some Rogers materials support high-temperature processing (including lead-free assembly conditions).
-
High Temperature & Chemical Resistance: Suitable for demanding environments such as automotive electronics and aerospace-related designs.
3) Mechanical Properties & Process Adaptability
-
High Dimensional Stability: Low moisture absorption improves stability under humidity and helps reduce deformation during processing and soldering.
-
Process Compatibility: Rogers materials can be used in hybrid stackups with FR-4 to balance performance and cost (common for RF + control mixed designs).
