Problems solved by technology

The disadvantages of the most traditional electric soldering iron are obvious, but for the modern controllable soldering station with ceramic heating core, the disadvantages mainly focus on the following aspects: 1. Due to the external heating method, the temperature conduction distance is long, and the soldering iron It takes a long time for the temperature of the head to reach the working temperature, and the loss of heat energy is large during the long-distance conduction of the temperature, and its working efficiency is low and energy consumption is high.
2. Due to the use of a temperature sensor, and the sensor is close to the ceramic heating core, there will be a large gap between the detected temperature and the actual temperature due to environmental temperature,
