NEVER FREEZE SOLDER PASTE. Recommended Profile This profile is designed to serve as a starting point for process optimization using LF-4300. To achieve better results with voiding or to reduce tombstoning, consider using a longer soaking zone, o (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 <90 seconds. Revised August 18, 2016
