Here's a basic question, I'm routinely getting soft solder on fine pitch connections (15-25 mils), the solder looks good but is just plain soft.  A probe can pop the leads very easily.  The boards are almost exclusively surface mount and are built and reflowed with a heat sink covering the entire board attached.  I believe the profile to be good or very close.  I am washing and baking all boards to lessen contamination issues yet I still see soft solder.  Any ideas OK
