If the surface of the gold-plated terminals of connectors, etc., has discolored or has foreign substances attached, there is a possibility that the gold plating is corroded.
Are there any green or white foreign substances attached to the surface of the gold-plated terminals? This may be a sign of corrosion occurring on the gold-plated terminals. Gold does not corrode, but the underlying metal beneath the gold plating can corrode. Corrosion issues with gold-plated terminals occur when the underlying metal corrodes and deposits on the gold plating. If corrosion products get caught in the connector's mating area, it can lead to poor contact. - There are visible defects on the surface of the gold-plated terminals with green, white, or black foreign substances. - I want to improve corrosion with the supplier, but I cannot obtain evidence of corrosion.
