Spread Weave Next Generation Laminate


EZ-IO-F is a thermally stable composite based on nanotechnology, spread weave and PTFE. Nanoparticle silica insures a drill quality on par with FR4 materials. EZIO-F is based on a very low (~10 wt%) fiberglass content. The nature of the spread weave provides a uniform dielectric constant and impedance as suggested by skew testing.

EZ-IO-F was created for the next generation of digital circuitry where ç. EZ-IO-F was also designed for microwave applications operating at increasingly higher frequencies where there is a need to combine both digital and microwave circuitry onto one PWB. EZIO-F was developed to challenge the best FR4 materials at the fabricator level in the most difficult 30-40 layer digital applications.
