Description

F4BME233 is a composite material produced via a carefully engineered formulation and precise manufacturing process, using fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and PTFE film. Compared to standard F4B laminates, it exhibits improved electrical properties, including a broader dielectric constant range, lower dielectric loss, higher insulation resistance, and greater overall stability. This makes it a suitable alternative to similar international products.

This material is supplied with reverse-treated RTF copper foil, delivering excellent passive intermodulation (PIM) performance, superior etching control for precision circuitry, and reduced conductor loss.

The dielectric constant of F4BME233 is accurately controlled by adjusting the ratio of PTFE to fiberglass reinforcement. This balance ensures both low signal loss and enhanced dimensional stability. Higher dielectric constant variants incorporate a greater fiberglass content, resulting in improved dimensional stability, lower thermal expansion, better temperature-dependent performance, and a corresponding increase in dielectric loss.
