In electric vehicle (EV) architectures, high-voltage (HV) traction systems coexist with low-voltage (LV) high-speed data networks, such as Automotive Ethernet. This configuration creates a complex electromagnetic environment in which impedance mismatches at connector interfaces can lead to signal degradation, electromagnetic interference (EMI) noncompliance, and power loss. This FAQ outlines the technical methods used to identify […]
How to manage EMI at the harness-to-PCB interfaces
Electromagnetic interference (EMI) at harness-to-PCB connections creates one of the biggest challenges in modern electronics design. These interface points act as weak spots where unwanted signals can escape your carefully designed circuits, causing system failures. This FAQ discusses four techniques that work in conjunction: shielded connectors, smart PCB layout, proper grounding, and common-mode chokes. When […]
What are the important standards for compliance with wire harness-to-PCB interfaces that engineers should know?
When connecting cable assemblies to PCBs, you need more than just a physical connection. These interfaces must meet specific industry standards to deliver minimal performance across different applications. Understanding the right standards for your project is necessary when applying to both consumer electronics and aerospace systems. This FAQ discusses the most common standards for the […]
