I will recommend the following papers for your reference.  

- Manufacturability and Reliability of Products Assembled 
  with New PCB Finish, by K. Banerji and E. Bradley (SMT proceedings '94)

- Printed Wiring Board Surface Finishes:  Evaluation of Electroless
  Noble Metal Coatings, by U. Ray, I. Artaki, G. Wenger and D. Machusak 

- Material Developments in Microelectronic Packaging:  
  Performance and Reliability (Proceedings of the 4th Electronic Materials
  and Processing Congress)

These papers will provide you with very good understanding of electroless 
Ni in terms of material characteristics, product quality and reliability.
