     We have a discussion going on with the IPC 610 B figure 4-23 
     and 4-24 which are on page 57. It seems we cannot come up with
     a majority rule on the insertion and soldering techniques of
     the coated capacitor.
      
     The statement which we are concerned with:   Exhibits all around
     good wetting on secondary side and lead coating meniscus is not 
     visible within connection on solder side.  We cannot understand why 
     solder side is also called secondary side in the same sentence.
     (Per the view 4-2 these mean the same.)
     
     Our situation is, we have some meniscus into the solder on the top 
     side or primary side with little or no wetting. We cannot ensure that 
     the vertical fill of solder is 75% per table 4-1 Class 2.   
     Also, there does not appear to be a minimum amount of lead space
     between the solder connection and the meniscus in 610 B.
     This application has been changed from 610 A TO 610 B.
     
     Thanks for any clarification we can get on this...
