Dale:
     I have done some selective soldering and have had mixed 
     success.  CCAs with bottom side surface mount had to have 
     been the toughest, however, the board itself was very dense 
     and spacing was not conducive to selective soldering for 
     that particular CCA, whereas others worked well.  Spacing is 
     key to allow solder flow.  I had a lot of success with 
     selective soldering flexes mounted to CCAs, connectors, and 
     some PTH with bottom side SMT.  Spacing is key.  I called 
     Eric Miller at Precision International, Ltd., and Eric was 
     very helpful.  Precision International has manufactured 
     fixtures for selective soldering.  Eric was able to send 
     some guidelines which were very helpful.  His number is 
     1-800-725-5388.
