Tips

When soldering this connector, ensure the PCB pads are designed for through-hole components with sufficient clearance. Use a soldering iron with a fine tip and avoid excessive heat to prevent damage to the PTFE dielectric. For high-frequency applications, keep the PCB trace impedance matched to 50 ohms to minimize signal reflection.
