I have a component with Nickel lead, a battery, and soldering/tinning it
has been troublesome.

I want to Ultrasonically Weld the leads to the PCB.  Can I do this with
PCB FR4 Material.  I was thinking if I cannot do it through the PCB
laminate, I might add a Via in pad and fill the via with Nickel plate.

The laminate is .030 and the finish option on the pads would be
Selective Immersion Ni, plated up to ???? 10um Maybe?

Any input appreciated....
