Introduction of Hf PCB
Printed Circuit, Bluetooth PCB
Sinofast high frequency PCB boards are widely used in wireless networks, wireless communications and satellite communications. In particular, the popularity of 3G, 4G, 5G networks greatly increases the market demand for Automotive PCB.
The increasing complexity of electronic components and switches continually requires faster signal flow rates, and thus higher transmission frequencies is required to meet the social market. It has also become more and more necessary for high frequency (HF) technology to view conductor widths as an electronic component.

Choosing a circuit material for a high-frequency PCB board is generally a trade-off, often between price and performance. But PCB materials are also selected by two key factors: how well they meet the needs of an end-use application and what kind of effort is required to fabricate a desired circuit with a particular material.
SinoFast processes high-frequency materials with improved dielectric properties. These have a very low loss factor, low dielectric constant, and are frequency independent.
For some special high-frequency PCB materials, such as: PTFE PCB material, Rogers PCB materials, we also have the production ability.
