One of the questions we're frequently asked is "why don't Metcal soldering irons require calibration." In fact, there are a number of soldering stations that no longer require calibration, partly because the IPC standards have changed.

Traditionally, a conventional soldering station uses a temperature measuring sensor that feeds back the heating element temperature (not the tip temperature.) In many systems, the temperature that is displayed is somewhere between the tip (working surface) and the heater, and then is fed back to the temperature control PCB. These temperature sensors can and do vary over time. This variance can cause the displayed temperature to be different from the measured tip temperature.
