Hi Pat-
     
     You don't need a special solder but rather a better flux. Nickel oxide 
     is very tough to solder because of the nature of the oxide itself 
     (very dense, coherent, etc.). You need to investigate using a more 
     active flux that can breakup the oxide. Warning -the more active the 
     flux, the more problems with corrosion. Work with your flux supplier 
     and find something a bit stronger than you are using now.

Hello All:
     
Can anyone tell me about soldering SMT parts to Nickle plated copper pads. 
Is there a special solder alloy that I should use?
