There have been mixed reviews. I am aware of one company which is in the process
of completing a 1000 unit evaluation.
In the past, I have noted some solderability issues, and while addressing that
found one interesting fundamental property: The solution temperature of Pd into
eutectic Solder on a phase diagram is 231øC. Once we stumbled upon that
information, all investigations were stopped.
Regards,
Allen
