Temperature Control of Wave Soldering Based on PID Technology
The PID controller,which was used to precisely control temperature of wave soldering,was designed based on increasing PID control algorithm and mono-chip computers.The control effect was also studied by field test.The results show that the deviation between the controlled temperature curve and the setting curve is-3-+3℃.The absolute values of temperature deviation is 1.1℃,and the climactic temperature of wave soldering is 1.9℃ higher than the setting temperature.The controller has better temperature controling stability and higher precision.
