I have a design engineer who wants the thinnest solder joint possible
     between to parts. These parts will carry no current and can be either
     nickel or tin plated on the outer surface.

     What is the thinnest solder joint that will not fail. Unit will see
     large amounts of vibration, but very little stress or shear. CTE
     mismatch will be small (both parts are plated iron alloys).

     Thanks in advance for your help.
