Recommended Profile
To achieve better results with voiding or to reduce tombstoning, as a starting point for process optimization using SynTECH-N-TF consider longer soaking zone, (140-180°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.
Application
SynTECH-N-TF is formulated for syringe, stencil printing, and rework applications on all PCB surface finishes. SynTECH-N-TF may be used for BGA sphere attachment and reballing. SynTECH-N-TF is also designed to work on all flip chip bumping and chip scale packaging sites.
Cleaning
No-clean tacky flux that can be left on the board for many SMT assemblies. For applications requiring cleaning SynTECH-N-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.
