1. Inspection Before Use
– Check for surface defects (scratches, plating damage) and dimensional consistency before assembly.
– Ensure the pin diameter matches the hole size of the connector housing to avoid loose fit or assembly difficulty.
2. Assembly Process
– Align the tapered tip with the connector hole and insert gently to avoid bending the pin.
– Use moderate pressure to press the pin into the housing until the knurled section is fully embedded, ensuring a secure anti-loosening fit.
– Avoid excessive force during insertion to prevent deformation of the pin or damage to the housing.
3. Wiring & Soldering
– For crimping applications: Use a precision crimping tool to attach wires to the pin tail, ensuring a stable electrical connection.
– For soldering applications: Use low-temperature solder (≤260℃) to avoid damaging the gold plating layer, and clean residual flux after soldering.
4. Environmental & Storage Notes
– Store pins in a dry, dust-free environment (temperature: 15–30℃, humidity: ≤60%RH) to prevent oxidation of the gold plating.
– Avoid exposure to corrosive gases or liquids (e.g., acid, alkali) to maintain conductivity and appearance.
5. Safety Precautions
– Wear anti-static gloves during handling to prevent electrostatic discharge (ESD) damage to electronic components.
– Do not use the pin beyond its rated current/voltage to avoid overheating or electrical failure.
