An OEM service and parts organization needed to distribute 40,000 sensors crucial to the operation of the equipment they sold over the last 10 years as part of their warranty coverage. These parts were in inventory storage for many years and were no longer produced. When samples of these sensors were inspected before shipment, the sensors were found to have black copper oxidation on exposed areas of the gold-plated contact leads. As a result, all 40,000 sensors were deemed unusable for their purpose, and no replacement was found.

Anti-tarnish VCI Solution

The OEM contacted ZERUST® for a solution to their corrosion issues. ZERUST® performed a custom cleaning service and removed the copper oxide formation without damaging the gold plating or the encased component. In addition, the cleaned sensors were packed in ZERUST® ICT®520-CB1 Anti-Tarnish VCI Film to prevent further copper oxidation.
