Würth Elektronik Board-to-Board Solutions Featured in Signal Integrity Analysis
Würth Elektronik's WR-BTB board-to-board connector series was highlighted in a detailed signal integrity analysis from DigiKey, emphasizing the importance of controlled impedance and low insertion loss for high-speed applications .
The analysis demonstrated that connector impedance matching to PCB transmission line impedance (typically 50Ω for single-ended or 100Ω for differential signaling) is critical to minimize return loss and insertion loss. Differential signaling is recommended for the highest data rates to reduce noise and interference .
Key Considerations for High-Speed Board-to-Board Connectors:
Impedance matching to 50Ω (single-ended) or 100Ω (differential)
Return loss and insertion loss frequency dependence
Near-end crosstalk (NEXT) and far-end crosstalk (FEXT) mitigation
Ground conductor placement to reduce noise pickup
Connector geometry and insulating material impact on impedance
The WR-BTB series is designed to support specified impedances and data rates for high-speed data applications, enabling designers to increase circuit density while maintaining signal integrity
