Solder Outgasing Voids | 16 May, 2006

Hi, I am having trouble with outgasing voids on my solder bumps.Substrate is Cu with electrolytic Au on it.Sometimes I use electrolytic Ni beneath Au.I am doing laser soldering so this process is fluxless.Its been observed that Ni is helping in reducing voids but they are still there. Can anybody suggest me the possible causes.
