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 n
on-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 1
9
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.
