RO4003C 2-Layer ENIG PCB – High-Frequency RF Board for 5G & Automotive Radar

1.Introduction to RO4003C Material

Rogers RO4003C is a high-performance woven glass-reinforced hydrocarbon/ceramic laminate that combines the electrical properties of PTFE with the cost-effective manufacturability of epoxy/glass. Designed for RF and microwave applications, it offers tight dielectric constant (Dk) control, low loss, and thermal stability without requiring specialized processing like PTFE-based materials.

Key advantages of RO4003C include:
CTE matched to copper for dimensional stability in multi-layer PCBs.
High Tg (>280°C) for reliability in extreme thermal conditions.
Low moisture absorption (0.06%) and consistent performance across frequencies.

2.Key Features of RO4003C PCB

Dielectric Constant (Dk): 3.38 ±0.05 @ 10GHz
Dissipation Factor: 0.0027 @ 10GHz (ultra-low loss)
Thermal Conductivity: 0.71 W/m/°K
CTE: X/Y/Z = 11/14/46 ppm/°C (prevents via cracking)
Surface Finish: Electroless Nickel Immersion Gold (ENIG) for corrosion resistance.
