Installation Process

Tools Required for Installation

• Torque wrench for ensuring proper compression.
• Alignment jig or guide (if necessary) for precise placement.
• Screwdrivers or hex keys for securing fasteners.
• Cleaning materials to prepare the PCB surface.

Step-by-Step Guide

1. Preparing the PCB:
   • Clean the PCB surface to remove dust, grease, or residue.
   • Verify the PCB’s thickness and material compatibility with the connector.
2. Aligning and Securing the Connector:
   • Place the connector over the designated footprint on the PCB.
   • Use alignment tools, if necessary, to ensure accurate placement.
   • Secure the connector using the provided fasteners, applying uniform pressure.
3. Ensuring Proper Compression for Optimal Performance:
   • Use a torque wrench to tighten the fasteners to the recommended torque value.
   • Verify that the connector is flush with the PCB to avoid performance issues.

Common Mistakes to Avoid

• Improper Alignment: Misaligned connectors can lead to poor signal performance and potential damage to the PCB.
• Over-Tightening or Under-Tightening: Deviating from recommended torque values can compromise the connector’s reliability and RF performance.
• Neglecting Surface Preparation: Dirt or residue on the PCB surface can hinder proper contact and electrical performance.
• Using Incorrect Tools: Ensure the tools used match the connector’s specifications to avoid damage during installation.
