Phil, I have run HASL boards and ENIG boards side by side for years without incurring any issues through a Sn63 solder pot, with the exception of increased masking at times when they need flat ground pads. But don't let that misguide you into thinking that wavesoldering using lead free solder and ENIG will not be without issue.

We are still running our Tin/Lead wave solder system. Would you expect the new ENIG boards to run under the same parameters as the HASL boards or would profiles need to be changed? Thanks in adavnce for your advice.
