Dear Ahmad
For weathering resistance - 1.0 micron gold - electro plated should be good
enough. When placing in the soil avoid abrasion as there would be no
guarantee of how much gold is left.
Sputtering thickness for porosity free - needs to be established. You can
check at what thickness the part is immune from concentrated Nitric acid
attack for 30 secs.

Lifetime a year or less for now. No Ni as RF circuitry is involved.

Ahmad,
What is the lifetime of the product? No nickel between the copper and the
gold?

Any suggestion on how thick a sputtered layer of gold on copper terminal is
necessary for corrosion protection? The gold sputtered copper terminals are
to be in contact with soil and probed periodically.
