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?
