     Hello TechNet!
     
     No-clean solder paste can leave a hard residue after reflow.  Even 
     though the residue may be benign, it can creat havoc at any Incircuit 
     operation.
     
     I am wondering how serious a problem this really is.  Is there anyone 
     out there that saved one of their cleaners to deal with this 
     situation?  I am sure our incircuit engineers have changed to the 
     super sharp probes.
     
     Would appreciate some discussion on the subject.  Thanks.
     
     I was also wondering about the high voltage question I posted last 
     week.  Has anyone noticed problems with no-clean flux and high 
     voltages in the 10KV-15KV range?
