The difference between single temperature zone reflow soldering and multi-temperature zone reflow so

Single temperature zone reflow soldering

Single temperature zone reflow soldering is to control the temperature change of the temperature zone with time according to the reflow soldering temperature curve, and the PCB board is stationary in the furnace. The advantages of this single temperature zone reflow soldering are that the investment is small, and the temperature is easy to track the setting curve. The disadvantage is that the temperature changes periodically, so the production cycle is long and the energy consumption is high. Single temperature zone reflow is sometimes used for small batch or smt experiments.



Multi-temperature reflow soldering

Multi-temperature zone reflow soldering is to divide the soldering furnace into several temperature zones with different temperatures according to the reflow temperature curve, and the PCB board passes through each temperature zone at a uniform speed to achieve preheating, reflow, cooling and other processes.
