F4BTMS265 Material Profile

F4BTMS265 is an upgraded high-reliability ceramic-reinforced PTFE dielectric substrate optimized from the standard F4BTM series. Filled with uniformly distributed nano-ceramic particles and ultra-fine glass fiber, it reduces glass fiber-caused electromagnetic interference, dielectric loss and structural anisotropy. Adopting low-roughness RTF copper foil as standard, it delivers low conductor loss and stable peel strength, and supports copper/aluminum base lamination. With excellent dimensional, thermal and dielectric stability, this aerospace-grade material serves as a high-performance substitute for imported high-frequency substrates in military and aerospace applications.

Typical Application Fields

Featuring ultra-low dielectric loss, minimal structural anisotropy, superior thermal stability and aerospace-grade reliability, F4BTMS265-based PCBs are well-suited for deployment in high-precision, phase-sensitive high-frequency electronic systems:

• Aerospace devices, space equipment and cabin electronic systems
• High-frequency RF and microwave circuit systems
• High-precision military radar equipment
• Antenna feed network components
• Phase-sensitive antennas and phased array antenna systems
• Satellite communication systems
