F4BTMS1000 High-Frequency PCB with 1.905mm Thick Core for Aerospace and Radar Applications

1.Product Introduction: Advanced Ceramic-PTFE Composite

The F4BTMS1000 represents a significant technological advancement in PTFE-based circuit materials, combining ultra-fine glass fiber reinforcement with nano-ceramic additives to achieve superior high-frequency performance. This next-generation material minimizes the fiber weave effect while delivering exceptional dimensional stability (CTE 16/18/32 ppm/°C) and a stable dielectric constant of 10.2 at 10GHz. The standard RTF copper foil construction reduces conductor loss and provides excellent peel strength, making it ideal for demanding aerospace, radar, and satellite communication systems where reliability and signal integrity are critical.
