          Soldering Irons Tend to work in the same way

          Sep. 11, 2018

          All conventional soldering irons tend to work in the same way: constant power and variable tip temperature. The power in Watts External Heating Soldering Iron supplied to the soldering tip is constant during soldering and determined by the tip temperature set-point. The problem is that during soldering the thermal load on the heater increases, and the temperature of even a correctly calibrated iron will naturally fall as it supplies thermal energy to the increased thermal load of the colder joint. In order to bring the joint up to reflow temperature, to speed up the soldering time or to reduce the iron's recovery time, generally the operator increases the iron tip temperature often up to its maximum setting. This, of course, increases the chance of damage being caused by overheating. In real world production environments, with differently sized solder joints, conventional soldering irons are unable to cope with the continuously variable thermal demands.
