High frequency board usually use FR4 glass fiber lamination, but also the whole of the epoxy glass cloth repression, more uniform color the entire pcb board, bright. Density larger than the low frequency pcb board
High-frequency electronic devices is the development trend, especially in the growing wireless networks, satellite communications, and information products to high speed and high-frequency, and voice communications products to large capacity and fast transmission of wireless, video, and data normalization.
Therefore, the development of next-generation products require high frequency board, satellite systems, mobile phone base stations and other communications products received must be applied to high-frequency circuit boards, and the inevitable rapid development in the coming years, will be a large demand for high-frequency board.
(1) The dielectric constant (Dk) must be small and very stable, usually the smaller the better signal transfer rate
(2) The dielectric loss (Df) must be small, which mainly affects the quality of signal transmission, the smaller dielectric loss the smaller signal loss
(3) Consistent with the thermal expansion coefficient of copper
(4) Low water absorption, high water absorption will affect the dielectric constant and dielectric loss at the time of moisture.
(5) Other heat resistance, chemical resistance, impact strength, peel strength, etc. must also be good.

2 Layers Rigid Copper PCB for Switch, Electronics Component FM Modulator Circuit
We are a profesional FR4 PCB Circuit Board manufacturer in China, and we can offer a various of single sided to multilayer PCB to you.
F (for flame) and R (for retardancies) and the 4 is a 4 epoxy.FR4 is a glass fiber epoxy laminate.FR4 is the Main material for PCB manufacture, it is the excellent quality and reasonable price material
FR-4 is widely used for single and multilayer boards, which has excellent thermal tolerance as much as 130°C. Now this type material FR-4 is more widely manufactured, but the hence is less costly.
>Glass-reinforced hydrocarbon and ceramic dielectric
>Excellent high frequency performance due to low dielectric tolerance and loss
>Stable electrical properties versus frequency
>Low Z-axis expansion and excellent dimensional stability
Tg value: tg135-tg180
surface treatment:Hasl lead free+gold finger
With 900workers,full-process equippted(including lamination.imersion Gold),we make 1~24layers board in guaranteed quality.
