To all PCB Design Conqueror's,

  I have a situation arising in our manufacturing facility. We are finally graduating
to bottom side SMT design. I am butting heads with the IE (Industrial Eng.) Dept. on
how close we can place via's to bottom side pads for caps and resistor's. Currently
we have a horizontal flow with vertical placement of parts running through the wave.
  I started routing boards with a clearance of .015" in any given direction from the
bottom side pads. My IE Dept. wants a minimum of .025" in any direction, without having
any source to base this on. Does anyone have a standard that they use or is there a 
spec that states how far from a bottom side pad a via should be? 

   Thanks.
