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
