RECOMMENDED PROFILE
To achieve better results with voiding or to reduce tombstoning, as a starting point for process optimization using
NC-560-LF-TF
consider longer soaking zone,
(170-220°C)
for 60-90 seconds, with a rapid pre-heat stage. If there is evidence of solder de-wetting, consider lowering the peak reflow temperature, or reduce the time above liquidus to <60 seconds.
CLEANING
NC-560-LF-TF
can be left on the board for many SMT assemblies. For applications requiring cleaning,
NC-560-LF-TF
can be cleaned using commercially available flux residue removers
STORAGE AND HANDLING
Tacky flux should be stored at room temperature (20-25°C). Syringes and cartridges should be stored vertically with the dispensing tip down. Properly stored tacky flux has a 12 month shelf life.
