I think Tony's approach, using Soldermask over complete Gold is brilliant,
and I wonder if it is more costly...it could be argued that it is less
expensive.

Given the very high cost per unit of metal deposited, never mind the control
issues, for both Electroless Nickel, and Immersion Gold, the cost of the extra
gold used probably gets lost.  (Did I mention absence of catalyst in Tony's
process?)

Hats off to you Tony, GREAT IDEA.
