Introducing our newly shipped 4-layer printed circuit board (PCB) engineered with high-performance materials—Rogers RT/duroid 5880 and RO4003C. This PCB is designed for high-frequency and broadband applications, offering exceptional electrical properties and reliability.

Material Introductions

RT/duroid 5880
Rogers RT/duroid 5880 is a high-frequency laminate made from PTFE composites reinforced with glass microfibers. This material features:
- Low Dielectric Constant (Dk): 2.2 ± 0.02 at 10 GHz
- Low Loss: Dissipation factor of 0.0009 at 10 GHz
- Uniformity: Randomly oriented microfibers enhance Dk stability.

RO4003C
Rogers RO4003C is a proprietary woven glass reinforced hydrocarbon/ceramic material that combines:
- Dielectric Constant (Dk): 3.38 ± 0.05 at 10 GHz
- Cost-Effectiveness: Utilizes standard epoxy/glass processing methods.
- Low Moisture Absorption: 0.06%, enhancing reliability.

PCB Specifications

Stackup:
