The reflow temperature profile is defined by the relationship of temperature versus time during heating. There are two basic temperature profile types: Ramp-Soak-Spike (RSS) and Ramp-to-Spike (RTS).

The soldering process involves four separate inputs (two surfaces, solder paste, and heat source); therefore, no single temperature profile is ideal for all products and heating methods.
