Modern electric vehicles require the transmission of high-frequency data for critical safety and autonomous driving functions. Signal integrity is highly vulnerable to degradation at physical connection points throughout the vehicle’s architecture. This makes selecting advanced interconnect technology a necessity to ensure a reliable data backbone for next-generation automotive platforms.
Why are high-frequency EV signals prone to degradation?
Signals can degrade because traditional soldering methods carry the risk of creating cold joints or poor connections. Furthermore, using standard through-board pins can cause resonance, which negatively impacts signal integrity. The soldering process itself can also introduce lasting quality problems that disrupt the connection, such as cold spots, voids, splatter, and cracks.
How do shorter press-fit pins reduce electrical resonance?
Press-fit pins are designed to be shorter than standard through-board pins, which significantly reduces electrical resonance. Minimizing this resonance is critical for achieving greater signal integrity. This allows automotive ethernet connectors to reliably support high-speed data transmission at speeds of up to 10Gbps.
What soldering defects do solderless connections eliminate?
Traditional soldering can introduce common anomalies that disrupt electrical flow. The solder-free assembly of press-fit pins removes the risk of signal-degrading manufacturing defects and lowers the risk of errors during production. Specifically, solderless connections avoid the quality problems typically associated with solder, such as cold spots, voids, splatter, and cracks.
How do press-fit connections maintain environmental stability in harsh conditions?
Automotive environments involve extreme temperatures and physical stress. Press-fit connections utilize a compliant, high normal force interface that enables movement to accommodate coefficient of thermal expansion (CTE) mismatches. This compliant interface ensures a strong, highly repeatable, and highly reliable connection that maintains excellent performance even under high-temperature cycling conditions.
