     Look at the Accel cleaning system. It spins the parts and pushes/pulls 
     the crud from the tight spots. I believe they are in Plano (Dallas) 
     Texas.

     I'm working on developing a cleaning process for SMT.  One of the 
     challenges on the product is very low part clearances.  In many cases, 
     the devices are mounted only 1 to 3 mils from the board.  Some devices 
     also have their bodies soldered to the substrate to provide an RF 
     ground.  The substrates are ceramic, and the soldering process is IR 
     reflow.
     
     Right now we are cleaning by hand in Axarel 2200.  This is time 
     consuming and marginally effective.  I'm looking for a faster, more 
     effective process.  Any suggestions?
     
     Thanks,
