Need conductive plating with 2000 hour salt spray resistance

May 22, 2017

Q. Looking for a plating that would pass these tests? Needs to be RoHS-compliant, so cadmium does not work. Currently have a company that engineered a plating that passed but we need a second source.

CORROSION RESISTANCE
- Plated parts shall be subjected to both neutral and acidic salt fog environments as separate independent tests.
- The neutral salt fog exposure shall include 2000 hours of continuous exposure to a 5% neutral salt fog spray in accordance with ASTM B117.
- The acidic salt fog environment shall include 336 hours of continuous exposure to a 5% acidic salt spray environment in accordance with ASTM G85 A4.

CONDUCTIVITY
- Using a suitable milliohm meter, capable of measuring resistance to the nearest .01 milliohms, the coating shall not have a resistance greater than 2.5 milliohms when tested in an unexposed condition and in an exposed condition per the requirements of corrosion resistance. The probes used for conductivity measurements shall not puncture or otherwise damage the plating

THICKNESS
.0012-.0015

Sorry forgot to add that this is being applied to Aluminum Alloy
