Mike:

I don't believe the laminate will affect the solderability of the board.
The only time I've encountered solderability problems with a silver finish
was when a subcontractor forgot to turn the rinse water on while processing
boards through the silver line.  Is there any discoloration or dullness of
the silver that might indicate contamination or oxidation of the pads?  Have
you performed solderability testing on the boards?  If Dave Hillman is out
there, he might want to comment on the ability of SERA or other methods to
evaluate the surface finish.

 Hi all,

I am currently having a few problems with soldering an Organic Silver
finished PCB.  The PCB is a Rodgers material, but I have no information on
the exact type.  I am using Multicore X33-12i no-clean flux, but this
appears to have no effect on the pads.  All of the joints are partial, and
have very poor wetting, if any!!  Has anyone had similar problems to this???
Any suggestions on how to fix this??  Unfortunately I can't use a clean flux
as I don't have the facility to clean PCB's.

Cheers

Mike
