How are you fluxing the tantalum capacitors. 
        Foam no clean and fixed head spray fluxers have trouble properly 
     fluxing small SMD pads. This usually shows up as skips and 
     insufficients, since some of the pad does see flux, but the rest is 
     shadowed from the fluxer, or blown clean by the flux air knife 
     (turbulence occurs where the air stream is deflected by the close 
     part).

Hi Technetters,
     
I am wandering anyone could suggest ways to get rid of solder skips.
     
We have a lot of solder skip on the Tant capacitor, case size type A 
and B, but don't have any problem with the rest of the chip components 
and SOICs. The pad size for the Tant Cap id pretty small, only allow 
very little for space for the chip wave to be able to solder to the 
terminations.
     
Any ideas how to fix it..We are running no-clean using a full-blow  nitrogen 
tunnel wave-solder machine.
