You mean time above solidus. Time above liquidus is vapor. Yes, 105 degrees in liquidus does seem excessive, but it depends on the size/mass of the CCA being soldered. It might be required for very large CCAs. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Fabien Guizelin Sent: Wednesday, April 04, 2012 6:04 PM To: [log in to unmask] Subject: [TN] Max time above liquidus Hi, Should I be concerned by excessive TAL ? (inter-metalic, etc) Do you consider 105sec TAL with a Indium 5.1 paste excessive ? (Indium recommends 45-60sec) Thanks, Fabien ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
