Lead Free Solder - Leaded Components

Is it possible to use lead free solder with leaded/lead all components?  What about the reverse - leaded solder with lead free components?

    If you are hand soldering there shouldn't be any problems (sometimes a little bit more difficult because of higher solder melting point).  In a Reflow situation there might be a problem because of the higher temperatures needed with lead free solder could damage some components.   Each part would have to be looked at individually with the solder process.

    Again, if you are hand soldering there shouldn't be any problems (sometimes a little bit more difficult because of higher soldering temp needed for the component).  In a Reflow situation there might be a problem if the higher temperatures needed for a component to bond to the solder are not reached.  Each part would have to be looked at individually with the solder process.

    Here is a comrehensive tech note from Kester.

     

    http://www.kester.com/Portals/0/Knowledge_Base_Articles/Lead-free%20Handsoldering.Final.4.19.06.pdf

     

    It may not addess your question directly but does have a lot of infor about lead-free soldering and, at the end of the note, provides a phone number and contact for expert information.
