High Frequency PCB Built on Rogers IsoClad 917 non-woven fiberglass/PTFE Materials
(Printed Circuit Boards are custom-made products, the picture and
parameters shown are just for reference)
Brief Introduction
Rogers IsoClad 917 laminates are non-woven fiberglass/PTFE
composites using a low ratio of fiberglass/PTFE to achieve the
lowest 2.17 or 2.20 dielectric constant and 0.0013 dissipation
factor. Longer random fibers and proprietary process of IsoClad 917
provide greater dimensional stability and dielectric constant
uniformity than competitors in similar classes.It is non-woven
fiberglass reinforcement, less rigid than woven fiberglass, so it’s
used in applications where the final PCB may be bent in shape,
including conformal antennas or wrap-around antennas.
Features
1. Low dielectric constant (Dk) of 2.17 or 2.20
2. Low dissipation factor of .0013 at 10GHz
3. Extremely low loss
4. Low moisture absorption
5. Highly Isotropic in X, Y and Z Directions
Typical Applications:
1. Conformal Antennas
2. Stripline and Microstrip Circuits
3. Guidance Systems
4. Radar Systems

Our Advantages
Founded in 2003, Shenzhen Bicheng Electronics Technology Co., Ltd
is an established high frequency PCB supplier and exporter in
Shenzhen China, severing cellular base station antenna, satellite,
high frequency passive components, microstrip line and band line
circuit, millimeter wave equipment, radar systems, digital radio
frequency antenna and other fields worldwide for 19 years. Our high
frequency PCBs are mainly built on 3 high frequency material
brands: Rogers Corporation, Taconic and Wangling. Dielectric
constant ranges from 2.2 to 10.2 etc.
We also have divisions of FR-4 circuit board, flexible circuits and
metal core PCBs featured as prototypes, small runs to mass
production. We also actively research and build such high value
added PCB projects as HDI, quick turn, impedance control, heavy
copper and backplane board etc. This has made our PCB products
generate an effective prolongation and complementation, as well as
formation of integrated products line ranging from low-end to
high-end.
