ABSTRACT

MCU STC15F2K60S2 was taken as the core controller. The heating core referred to white light T12 soldering head consisting of the thermocouple sensor in series with heating wire. The energy generated by the heating wire was used to control the temperature through PID. Multi-functional NCN digital display soldering station based on MCU was designed to achieve accurate temperature detection and control of soldering iron, which remained in a constant temperature working state. Experimental results showed that the system had controllable welding temperature, high precision, little temperature error (±1%) and wide temperature control range (10-550 °C). Five sets of user parameters were saved to achieve numerical control, digital display, automatic standby, automatic sleep, voice prompts and electrostatic prevention. Therefore, the system had strong practicality, high reliability and low cost.
