Customer Success Stories
Real-world applications of Yichangda RF connectors, antennas, and cable assemblies.
European Handheld Radio Brand 2024
Challenge: Client’s supplier delivered connectors with unstable low-temp performance and fluctuating PIM, causing high batch failure rates.
Process: First samples showed PIM variation across batches. We traced it to inconsistent plating thickness and revised the process control — second round passed.
Solution: Optimized gold plating thickness and contact structure for SMA connectors and RG58 assemblies.
Consumer Drone Video Transmission Maker 2026
Challenge: Tight internal space caused poor impedance matching, signal dropouts in flight.
Process: Initial antenna simulation didn’t match real-world test results. We adjusted the tuning based on actual flight data — third iteration nailed it.
Solution: Custom FPC antennas with simulation tuning, SMT PCB-mount receptacles.
5G Base Station Equipment Supplier 2023
Challenge: Previous connectors failed outdoors — 48-hour salt spray life, contact degradation.
Process: First sealed design had moisture ingress at the cable entry point. We redesigned the grommet — retest passed.
Solution: 4.3-10 low-PIM connectors, thickened gold plating, sealed construction.
North American In-Vehicle IoT Maker 2025
Challenge: Vehicle vibration loosened connectors, intermittent signal loss.
Process: Standard lock washers didn’t hold under sustained vibration. We developed a custom anti-loosening structure — validated on shaker table.
Solution: Vehicle whip antennas and PCB connectors with anti-loosening locks.
