IsoClad 917 laminates use a low ratio of non-woven fiberglass/PTFE to achieve the lowest dielectric constant and dissipation factor available in its class. The non-woven reinforcement allows these laminates to be used in applications where the final PCB may be bent in shape, including con-formal or wrap-around antennas. IsoClad’s longer random fibers and proprietary process provide greater dimensional stability and dielectric constant uniformity than competitors in similar classes.
