I have a couple basic questions on the cost of (to me at least) exotic
coating/plating requirement.  These PCB's are electromechanical in
application as they contain a few passive components and the plating is
also a contact for a mechanical switch wiper contact.  My customer is
calling for the following (on various boards, about 1 dozen p/n's):

1.  200 u-in. of sulfamate mickel plating on wiping surface, matte
finish electroplate is acceptable.
2.  Minimum 100 u-in. of ductile sulfamate nickel plating
3.  Nickel plated, 0.0038 mm min., plated thru holes

Are these spec's going to cost more than HAL/SMOBC in large production?
(Asian PCB source).  Also, is there any issue soldering 1206 and 0805's
in convection reflow on this plating?

P.s.  This is how their notes read. I assume the "mickel" is really
supposed to be "nickel".

Any help would be appreciated. Thanks in advance!


All the best...
