: The duration the solder remains in a liquid state.

, officially titled Guidelines for Temperature Profiling for Mass Soldering Processes , is the industry standard for creating and managing thermal profiles in electronics manufacturing. It ensures that all solder joints reach the necessary temperatures for metallurgical bonding without damaging heat-sensitive components. IPC-7530

The current version is (released January 2025), which expands beyond reflow and wave soldering to include vapor phase, laser, and selective soldering processes. Core Stages of a Thermal Profile

A compliant thermal profile typically consists of four critical phases:
