General Description
Rogers' (Arlon) TC600 is a woven fiberglass reinforced, enhanced
thermal conductivity ceramic filled, PTFE-based composite. It is
designed to provide enhanced heat-transfer through“Best-In-Class”
thermal conductivity, while reducing dielectric loss and insertion
loss. The increased thermal conductivity (1.1 W/mk) provides higher
power handling, reduces hot-spots and improves device reliability.
Lower losses result in higher amplifier and antenna
gains/efficiencies. Stable dielectric constant is across a wide
temperature range (-75 ppm/oC -40°C to 140°C). It helps power
amplifier and antenna designers maximize gain and minimize dead
bandwidth lost to dielectric constant drift as operating
temperature changes. It has low Z-Direction CTE and mechanical
robustness is also greatly improved for the 6.15 dielectric
constant market.
Features
1. Very Low Loss Tangent (0.002 at 10 GHz) provides Higher
Amplifier or Antenna Efficiency
2. Mechanically Robustness improves processing and reliability,
replaces brittle laminates that cannot withstand processing, impact
or High Gain forces
3. Low coefficient of thermal expansion on X,Y and Z axis (9, 9 and
35 ppm/°C) matches active components for low stress solder joints
4. High Peel Strength for Reliable narrow lines
Benefits
1. Reduced Heat Generated through Transmission Line Loss
2. Heat Dissipation and Management
3. Replace Ceramic in Some Applications
4. Large Panel Sizes for Multiple Circuit Layout for lowered
Processing Costs
