Recommended Profile

To achieve better results with voiding or to reduce tombstoning, as a starting point for process optimization using SynTECH-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

SynTECH-LF-TF can be left on the board for many SMT assemblies. For applications requiring cleaning, SynTECH-LF-TF can be cleaned using commercially available flux residue removers such as INVENTEC Promoclean™ and Promosolv™ cleaning chemistries.

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.
