IMO you should use the same alloy that you use for your reflow process. I
wouldn´t go with something special.
If you´re in need of putting non eutectic balls on that device - I can´t
suggest a tool ( haven´t done it myself ).
For eutectic balls you don´t need preformed balls, there´s a tool, for
example from WELLER, to print paste on the device and than reflow that
arrangement to form the balls.
Hope that helps a bit
