RO4003C PCB: 2-Layer, 16mil Core, ENIG Finish
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
Overview of the 2-Layer RO4003C PCB
The 2-layer RO4003C PCB is a high-performance laminate designed for RF and microwave applications requiring low loss, tight dielectric constant (Dk) control, and cost-effective manufacturability. Built with Rogers RO4003C material, this PCB provides the electrical performance of PTFE-based laminates but with the processing ease of FR-4, eliminating the need for special handling and through-hole treatments.
With a 16mil (0.406mm) core, ENIG (Electroless Nickel Immersion Gold) surface finish, and black silkscreen, this PCB is engineered for high-frequency stability and long-term reliability, making it ideal for cellular base station antennas, automotive radar, and satellite communication systems.

Introduction to RO4003C Material
Rogers RO4003C laminates are woven glass-reinforced hydrocarbon/ceramic materials offering high-frequency performance similar to PTFE-based laminates but at a fraction of the cost. These materials are easy to process using standard FR-4 techniques, providing cost-effective solutions for high-volume and performance-sensitive applications.
Key advantages include:
- Tight control on dielectric constant (Dk): Ensures consistent and stable performance across applications.
- Low Z-axis CTE: Provides reliable plated through-hole (PTH) quality under thermal shock conditions.
- Ease of Processing: Processes like FR-4 without the need for special handling.
