Simulation for High-Speed Connector Design

It’s Not Just a Case of Joining Metal and Plastic

Signal transmission across PCBs in multi-boards is frequently done using high-speed connectors. In signal integrity and channel analysis of a system, investigation of their features is crucial. In this application note, a high-speed differential connector is modelled and 3D complete wave simulations of the connector are shown in a lab setting. Comparing laboratory experimentation reference measurement data with simulated connection properties.

Opposing Ideologies in High-Speed Connector Design

There are two competing concepts in the high-speed connector design field. For some people, a signal transmission can be created by simply joining parts of plastic and metal. This technique is pretty easy to follow.

On the other end of the spectrum, there is the notion that a reliable connector design necessitates a profound comprehension of electromagnetic theory—a knowledge that is only available to sorcerers and wizards. The truth is ambiguous, as it is with practically everything in life. Our team will make an effort to demystify several high-speed connector design principles in this on-demand webinar.

Specializing in High-Speed Connector Design

Companies wouldn’t have specialized teams solely for connector design if the design of high-speed connectors were straightforward. These teams are made up of signal integrity (SI), mechanical, and manufacturing engineers on the engineering side alone. If mechanical engineers discuss normal force or mating cycles, manufacturing engineers discuss tooling or molding, and SI engineers discuss impedance, crosstalk, and insertion loss.

Additionally, this is not considering the business aspect because engineers typically do not give too much thought to costs. As we can see, designing high-speed connectors involves many different disciplines and is more complicated than just joining metal and plastic.
