By using SuperCORR A lubricant from Envirotech, a company in the US has been able to prevent galling corrosion due to vibration on printed circuit leads and connectors.

SuperCORR A

The company found that because of the advances in gold-plating technology, the plating thickness was being reduced over the base substrate metal of the connectors. The thickness of the gold plating became thinner and thinner over time.

Although the thinner coating saved a lot of money as gold is becoming increasingly expensive, the resulting reduced thickness of gold plating also resulted in failures caused by corrosion. Minute irregularities in the surface of the connector’s base metal caused irregular or uneven wear of the connector, causing the ‘high spots’ on the connector to wear through the gold plating.

SuperCORR A, a lubricant with corrosion preventive compounds, eliminated or delayed the corrosion and subsequent failures.

The company also had SuperCORR A tested to see what the life of the lubricant was in a rub test. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures.

It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the USB connectors at all.
