This is true with some Ni Pd Au systems as has been reported to me by some
military end customers. However not all systems are incompatible with
SnPb. You should check with your fabricators chemical supplier for details
on their compatibility.

Re: [TN] Build backplane with lead free HASL surface finish?
Wetting and intermetallic strength. My impression is that Palladium needs
an elevated temperature to solder well as it works fine at leadfree
temperatures but not SnPb.
This was also a big issue with Pd plated passives some years ago but I
don't know if it's directly comparable.
Best regards

Re: [TN] Build backplane with lead free HASL surface finish?
Dear Experts,
What are the different RoHS component lead finishes? Will any RoHS
component lead finishes have solderability issues if used with a leaded
paste?
Thanks in advance.
