Wonder if anyone could help....

I just recently started using gold tinted PCB's with leadfree. I didn't get
the result I was expecting, meaning the final end product solder ability
looked dull. We have had to rework at least 40% of the PCBs.

What is the criteria for lead free profile using gold surface finishes PCBs?
Am I using the correct profile?

The profile I'm using is 175/200/290 oC

Thanks.
