Hi there Technetters,

I have now exhausted my efforts of improving the solderability (T/H) of some
RF Organic Silver PCB's we are currently making.  Every attempt to improve
the solderability has had no impact.  The soldered PCB's show very poor
wetting, partial joints and in some areas there is no evidence of solder.
The PCB is curretly being pre-heated to around 160 deg. C topside and a bath
temperature of 256 deg. C.  Is there something I am over looking with the
Organic Silver?  Is there any special method/ or profile for Organic SIlver
finished PCB's???  Any feedback would be appreciated.

Cheers

Mike
