Why Use Rogers RO4003?
Rogers RO4003 delivers an exceptional balance of electrical, mechanical and manufacturing benefits including:
Stable Dielectric Constant - Low DK variance (±0.04) across fabrication batches enables reliable, consistent impedance control and signal performance meeting target design specs through iteration.
Low Loss Tangent - With average loss tangent of just 0.0021 at 10 GHz, RO4003 prevents excessive signal degradation as energy transmits through the PCB medium. This preserves range and efficiency in wireless links.
High Frequency Stability - Consistent electrical properties persist without shifting or introducing losses up to gigahertz frequencies and across typical operating temperature swings encountering in electronics equipment.
Standard PCB Process Compatibility - Unlike more exotic ceramic or PTFE substrates, RO4003 works well with widely accessible circuit board etching, drilling and plating processes available at most board fabrication shops.
Environmental Robustness - The ceramic-reinforced composite demonstrates resilience against humidity, extreme temperatures, and thermal shocks over decades of use further increasing reliability.
