The oxidation of contact components leads to an increase in resistance. How to deal with and prevent this?
Oxidation of Contact Pins: Treatment & Prevention
Treatment Measures
- Oxide Removal: Gently polish oxidation layer with fine sandpaper (metal components only) to avoid damaging base material
- Thorough Cleaning: Clean contact surfaces with anhydrous ethanol to remove polishing residue and contaminants
- Component Replacement: Replace severely oxidized contact pins to ensure stable electrical performance
Preventive Measures
Premium Plating Selection
Choose gold-plated contact pins to form a protective layer that resists oxidation and reduces contact resistance.
Environmental Control
Avoid long-term exposure to high-humidity or corrosive environments; use sealed enclosures for outdoor applications.
Idle Protection
Install dust caps on idle connectors to seal contact surfaces and prevent moisture/dust from causing oxidation.
Technical Note: For connectors in marine or coastal environments, apply anti-corrosion grease (compatible with plating) to contact surfaces to extend oxidation resistance by up to 3 times.
