"Far too many engineering teams leave stackup design, which is critical to signal integrity, to PCB fabricators, who are—more often than not—working with little electrical engineering expertise. As someone who’s designed more than 1,000 stackups over the years, I must say that I find Z-planner to be an exceptional stackup-planning tool. It has the most comprehensive library of laminates I have seen and is very user friendly. It would be an excellent addition to any signal integrity engineer’s tool set.”
