TC350 Plus laminates are ceramic-filled PTFE-based woven glass reinforced composite materials.
Have thermal conductivity of 1.24W/mK; ideally suited for higher power microwave and industrial heating applications requiring higher max. operating temperatures, low circuit losses, and excellent thermal dissipation. Advanced filler system enables composite to have improved mechanical drilling performance. Offered with smooth (Rq= 1.0µm) electrodeposited copper foil cladding to reduce insertion loss and RF heating of conductors. Resistive foil and metal plate options are available upon request. Are available in thicknesses from 0.010" to 0.060". Features include z-axis CTE of 38ppm/°C, loss tangent of 0.0017 at 10GHz, moisture absorption of 0.05%, dielectric strength of 650V/mil, and UL 94 V-0 flammability performance.
