One of our special products is high frequency pcb, From Rogers3000 series to Rogers4000 Series , from Metron4 to Metron6 , from FR408HR to TU872 . we have all these material in stock . we understand High Frequency pcb required very strict fine line and impedance control . so we have special etching parameter , this is different with other multilayer pcb etching .also pattern plating line parameter is different . cause these material is very expensive , so yield rate need to up to 90% , or we can’t make money . We believe we can do it . always here with you .


What is High frequency pcbs?

High Frequency PCB is a type of PCB which is widely used in applications involving special signal transmission between objects. It is available in frequency range of 500MHz to 2GHz and is an ideal choice for mobile, microwave, radio frequency and high speed design applications.

What Kind of High frequency pcb we can do?

Fast turn pcb is very good at making pcb antenna, PTFE pcb and 5G PCB. Till now we got many orders from USA, Europe, Such as: Germany, England, Italy. And our Antenna board quality didn’t got any complain from our customers.


High-Frequency PCB Advanced Circuits Specification

Electronic devices with high frequency are the developing tendency nowadays, especially in the wireless networks. Satellite communication growing rapidly, information products move towards high speed and high frequency. Thus developing new products always need to use high frequency substrate, satellite system, mobile telephone receiving base station and so on, these communication products must use high frequency PCB.

High frequency board for wireless applications and data rates in the upper GHz range have special demands on the material used:

1. Adapted permittivity.
2.Low attenuation for efficient signal transmission.
3.Homogeneous construction with low tolerances in insulation thickness and dielectric constant.
Generally speaking, high frequency can be defined as frequency above 1GHz. Currently, PTFE material is widely used in high frequency PCB manufacturing, it’s also called Teflon, which frequency is normally above 5GHz. Besides, FR4 or PPO substrate can be used to the product frequency among 1GHz~10GHz. These three high frequency substrates have below differences:
Concerning the laminate cost of FR4, PPO and Teflon, FR4 is the cheapest one, while Teflon is the most expensive one. In terms of DK, DF, water absorption and frequency feature, Teflon is the best. When product applications require frequency above 10GHz, only can we choose Teflon PCB  substrate to manufacture. The performance of Teflon is far better than other substrates, However, the Teflon substrate has the disadvantage of high cost and large heat-resisting property. To improve PTFE stiffness and heat-resisting property function, a large number of SiO2 or fiber glass as the filling material. On the other hand, due to molecule inertia of PTFE material, which it is not easy to combine with copper foil, thus, it needs to do the special surface treatment on the combination side. Concerning combination surface treatment, normally use chemical etching on PTFE surface or plasma etching to plus surface roughness or add one adhesive film between PTFE and copper foil, but these may influence dielectric performance.
