Practical Solutions for Addressing Pogo Pin Contact Failure
Short-Term Solutions
Increase Contact Force: Appropriately adjust the installation position to increase the compression stroke (within permissible limits).
Use Conductive Lubricant: Where applicable, use specialized conductive lubricant to reduce friction and oxidation.
Long-Term Solutions
Optimize Design:
Select appropriate spring force to ensure sufficient contact pressure.
Increase the gold plating thickness (recommended minimum: 0.76µm).
Design reasonable alignment structures and guiding mechanisms.
Material Upgrade:
Use higher-performance spring materials (e.g., music wire).
Choose more wear-resistant contact materials (e.g., rhodium, palladium alloys).
Consider using plating combinations with better oxidation resistance.
Process Improvement:
Strengthen cleaning and contamination prevention measures during the production process.
Implement stricter quality control and inspection standards.
Optimize soldering processes to avoid flux contamination of the contact surfaces.
Protective Measures:
Design effective sealing structures to prevent contaminant ingress.
Add self-cleaning features, such as contact pin wiping designs.
Use anti-corrosion coatings to protect non-contact areas.
