What is the Taconic EZ-IO-F laminate?
EZ-IO-F is a thermally stable composite that leverages nanotechnology, spread weave fabric, and PTFE to deliver superior performance. The incorporation of nanoparticle silica ensures drilling quality comparable to that of FR4 materials, while the low fiberglass content (~10 wt%) contributes to its advanced properties.
The unique spread weave construction of EZ-IO-F provides a uniform dielectric constant and impedance, as evidenced by skew testing. This makes it ideal for the next generation of digital circuitry, supporting digital transmission speeds starting at 25 Gbps and reaching up to 112 Gbps.
Moreover, EZ-IO-F is perfectly suited for microwave applications operating at increasingly higher frequencies. It meets the demand for combining both digital and microwave circuitries onto a single printed wiring board (PWB). Designed to challenge even the best FR4 materials in complex, multi-layered digital applications (30-40 layers), EZ-IO-F represents a significant advancement in PCB material technology. Its exceptional characteristics make it an optimal choice for fabricators facing the most demanding projects.
It is manufactured on industry leading no profile copper. The newer ULP copper outperforms rolled copper and is the new benchmark for high performance laminates. Significant reductions in insertion loss can be achieved with ULP copper vs. HVLP or rolled copper.
By integrating these advanced features, EZ-IO-F not only supports but also enhances the performance of cutting-edge electronic systems, ensuring reliability and efficiency in high-speed and high-frequency environments.

What are the skew testing on the Taconic EZ-IO-F laminate?
Skew testing suggests a maximum skew of 0.3 picoseconds/inch and an average skew of <0.1 ps/inch with no artwork rotation. Artwork rotation of 15° shows a maximum skew of ~0.05 ps/inch and an average skew close to zero. Interestingly enough, skew is flat over frequency when tested from 1-20 GHz.



Manufacturing of the Taconic EZ-IO-F laminate
The laminate achieves its peak performance when combined with AGC’s FR-28-0040-50S (DF = 0.0018 at 10 GHz) non-reinforced prepreg, resulting in a stripline channel with approximately 5% fiberglass content. This combination is designed to optimize performance while maintaining material integrity and consistency.
That fastRise™ prepregs stand out as the lowest loss prepregs commercially available that can be laminated at FR4-like temperatures of 420 °F. The low insertion loss characteristic of the EZ-IO-F/fastRise™ pairing rivals that of pure PTFE laminate fused through bonding, a process known for its high cost and significant material movement issues.
Notably, fastRise™ is particularly well-suited for applications operating at frequencies up to 77 GHz. It competes favorably with any fusion-bonded laminate but without the associated costs and technical challenges. This makes the EZ-IO-F/fastRise™ combination an exceptional choice for fabricators seeking high-performance materials that offer superior electrical properties alongside ease of use and cost-effectiveness.
EZ-IO-F can be obtained with the lowest profile resistor foils. The nanoparticle’s design and lack of surface porosity enable the etching of very fine lines (2-4 mil lines and spaces).
In summary, by leveraging the advanced features of both EZ-IO-F and fastRise™ prepregs, designers can achieve unparalleled performance in high-frequency applications, ensuring reliability and efficiency without the drawbacks of more complex and expensive processes.
