Gurus,
what is the std plating surface finishing  of ferrous metal  
components leads?  Cu or Ni underlying layer (thickness X-micron)  
with solderable surface for lead free? (98% Tin for example, assume  
flash gold is too expansive  - >2000 per oz, shish).  Anything in the  
field  that is new?  Is standard change from MIL to ASTM  for the  
plating?  Many thanks.
regards,
jk
