Features of the Rogers TC350 PLUS laminate
High Thermal Conductivity (1.24 W/m•K)
Heat dissipation is a critical challenge in high-power designs. With a thermal conductivity of 1.24 W/m•K, TC350 Plus efficiently transfers heat away from active components, reducing thermal stress and enhancing system reliability. Reduces the risk of overheating, contributing to longer component lifespan and improved reliability under high power conditions.
Low Loss Tangent (0.0017 at 10 GHz)
The ultra-low dissipation factor ensures minimal signal attenuation, even at frequencies as high as 10 GHz. This makes the material ideal for applications requiring precise signal integrity over wide bandwidths. Supports higher data rates with lower power consumption, enhancing overall system performance.
Very Low Insertion Loss & Reduced RF Heat Generation
The laminate’s low insertion loss minimizes energy waste in RF circuits, while its ability to reduce conductor generated heat ensures stable operation under prolonged high-power conditions. Minimizes losses in transmission lines, ensuring efficient power delivery and signal propagation.
Low Z-Axis CTE (38 ppm/°C)
A low coefficient of thermal expansion (CTE) in the Z-axis prevents delamination and via cracking during thermal cycling, ensuring long term durability in fluctuating temperature environments. Facilitates precise fabrication, critical for maintaining tight tolerances in advanced electronic designs.
Low Moisture Absorption
The low moisture absorption of 0.05% to ensure stable performance in a range of operating environments, TC350 Plus maintains consistent electrical and mechanical properties even in humid conditions, making it suitable for harsh operating environments.
UL 94 V-0 Flammability Rating
The material meets the stringent UL 94 V-0 standard for flame resistance, ensuring safety in high temperature applications and compliance with industry regulations.
