Bill Hargin is the director of everything at Z-zero, providing stackup design and PCB material selection software to OEMs, ODMs and PCB fabricators worldwide. Hargin is an author of multiple articles on signal integrity, a regular columnist for Printed Circuit Design and Fabrication, and more than 10,000 engineers and PCB designers worldwide have taken Hargin’s workshop on high-speed PCB design. With more than 20 years of experience dealing with PCB signal integrity, Hargin served as director of marketing for Mentor Graphics’ HyperLynx SI software and as the director of North American Marketing for Nan Ya Plastic’s PCB laminate division in Taiwan.
Engineers invest tens to hundreds of thousands of dollars in signal integrity simulation software—the goal being to gain an accurate understanding of how signals are going to behave in the final product. But how do you do that early in the design process without reliable, verifiable electrical properties for the dielectrics incorporated into your design?
