Hi

Not sure about using low melt solders but this finish always shows higher levels of voiding with a tin/lead process. Not my favourite finish!

Cheers

Dear All, Good Morning,   Looking for some knowledge base  on soldering NiPdAu finished components with low melt solder such as Sn42.0Bi57.6Ag0.4 to avoid wetting issues on a heavy copper plane board. Any insight and advise will be appreciated.

Thank-you
