"Typically, engineers roll their own stackups using spreadsheets—grabbing Dk and Df values from datasheets for simulations—ignoring resin content and frequency … Or relying heavily on third party fabricators to resolve final-implementation details with stackup and materials long after SI simulations were performed.
"Certainly, known tools have been around for years in this space, but no software on the market accessibly considered the major (known primarily by fabricators) issues surrounding stackup design combined with an accurate field solver and loss-planning environment, along with a complete dielectric materials library—and seamless interfaces to popular PCB signal integrity software—bundled in a powerful, affordably priced, easy-to-use tool … That’s how Z-planner was born."
Professional Experience

“Survival in the world of high-speed design requires accurate prediction of electrical performance based on design and material properties. Z-zero’s focus on accurately modeling the detailed elements of PCB stackups is a valuable contribution to the industry.”
