SuperCORR A protects thinner gold plating used on electrical contacts from corrosion

By EnviroTech Europe Ltd on

Product Details Supplier Info More products

SuperCORR A ultra-thin film dry lubricant prevents galling corrosion caused by vibration on printed circuit leads and connectors. 

Advances in gold plating technology allows manufacturers to reduce plating thickness on the substrate metal used for contacts in electrical connectors.

The thickness of gold plating is decreasing and becoming thinner over time which reduces manufacturing costs as gold becomes increasingly expensive.

Reducing thickness of gold plating however can result in failures caused by corrosion. Minute irregularities in the surface of the connector’s base metal leads to irregular or uneven wear causing the “high spots” on the contacts to wear through the gold plating. Using SuperCORR A aerosols prevents or delays corrosion and subsequent failures. 

TESTING SuperCORR A IN CONNECTOR “RUB TEST”.

 SuperCORR A is a lubricant containing corrosion preventive compounds, and as is the case with all lubricants they will be worn off over time. A manufacturer of connectors tested SuperCORR A 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. The USB connector looked and tested as good as new.

MILITARY USES OF SuperCORR A

 As it is compliant with Mil-L-87177A specifications SuperCORR A is used by the U.S. Air Force to protect the intricate workings of the F-16 Fighter Jet and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for electrical and close mechanical application, especially where flights are in salt fog or high humidity.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors SuperCORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electro migration problems. The ultra-thin, non-flammable lubricant film is only 7 microns (0.0007 inch) thick and is formulated without sulphates, chlorides or halogens to meet the EU RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.
