Need more info:
What type of components?
What's the base metal?
Is this a palladium alloy? With what?
How will these components be soldered?
What's the requirements (temp, life cycle, etc) of the assy?
Simplistic questions with no info to assist those people on the Net who
would like to help deserve simplistic answers with no info.

We have a vendor who is changing the metallizations of its components
to palladium from tin/lead.
Has anyone had problems with this?
Are there problems with no-clean fluxes?
