| Abstract: | Reflow soldering is a key technology Jn SMT, and the tem- perature control is important in the process. This paper mainly expounds a temperature- measure-control system, which is composed of monolithic computer and LCD screen and adopts beforehand PID arithmetic method. The computerized system can automatically regu- late temperature, collect and display the temperature signals, realize automation loop-control of the temperature rise and fail, and have self-study and memory functions. |
