PCB connector suppliers are often tasked with providing connectors that meet today’s high-speed and high-density requirements. In many cases, these connectors also need to maintain signal integrity under harsh conditions. Such models make it possible to simulate how the connector will interface and perform in its surrounding environment. IEH has partnered with Modelithics to offer 3D geometry models for various IEH hyperboloid connector products.

Successfully designing a PCB with more than one impedance while maintaining a manufacturable and economical product can be a difficult challenge. By examining the histories and uses of various impedances, Lee Ritchey simplifies the process and discusses the ideal impedance for PCB stackup design.

We care about maintaining the same differential impedance for the same reason we care about maintaining the same instantaneous impedance of a single-ended (SE) transmission line: to avoid reflections. SIJ’s EAB member Bert Simonovich explains the fundamentals and why it matters.
