⚠️ Notes

• Ensure Correct Pin Alignment: Check orientation and positioning before mating to avoid mis-insertion, bent pins, or PCB pad damage.
• Do Not Exceed Electrical Ratings: Follow the specified current and voltage limits to prevent overheating or contact failure.
• Proper Insertion and Extraction Force: Avoid excessive force during mating/unmating to prevent deformation, cracked solder joints, or pin damage.
• Keep Contact Surfaces Clean: Ensure terminals remain free from dust, oil, oxidation, or contaminants that reduce conductivity.
• Follow Recommended Soldering Conditions: Use appropriate soldering temperature profiles according to plastic materials such as LCP, PA6T, PA66, or PBT.
• Verify PCB Hole Tolerance: Incorrect hole size may cause inadequate solder filling or mechanical instability.
• Avoid Mechanical Stress After Assembly: Do not apply lateral pressure or bending forces, especially for SMT pin headers.
• Maintain Proper Storage Conditions: Store in a dry, dust-free environment to prevent terminal oxidation; use anti-static packaging if required.
• Confirm Compatibility with Female Header: Ensure matching pitch, pin count, height, and contact design to avoid mating failure.
• Choose Correct Plating Specification: Select proper plating (gold, tin, nickel) based on your application’s durability, corrosion resistance, and signal reliability needs.
