Rogers CLTE PCB (Low CTE Ceramic Thermoset Laminate) is a high-performance printed circuit board material engineered for applications demanding exceptional dimensional stability and thermal reliability. Designed by Rogers Corporation, CLTE-series laminates feature a ceramic-filled PTFE composite construction that delivers an ultra-low Z-axis coefficient of thermal expansion (CTE), making it the preferred choice for RF/microwave assemblies, aerospace electronics, defense systems, and high-frequency communication devices.
Key Features & Technical Advantages
- Ultra-Low Z-axis CTE – Minimizes plated through-hole stress during thermal cycling, significantly extending board reliability and service life
- Stable Dielectric Constant (Dk ≈ 2.94–3.00) – Ensures consistent signal integrity across wide temperature ranges (-55°C to +150°C)
- Low Dissipation Factor (Df ≈ 0.0012) – Ideal for high-frequency, low-loss RF and microwave circuit designs
- Superior Dimensional Stability – Tight X/Y tolerances critical for phased array antennas and precision multilayer stackups
- Excellent Chemical Resistance – Compatible with standard PCB fabrication and assembly processes
Typical Applications
Rogers CLTE PCBs are widely used in satellite communication systems, radar and phased array antennas, automotive radar (77 GHz), 5G base station infrastructure, and military/defense electronics where thermal performance and signal fidelity are non-negotiable.
