A Brief Discussion on How Laser Soldering Temperature Control System Precise Temperature Control

In daily operations, many customers inquire about the necessity of a temperature control module during the laser soldering process. How does this module regulate the temperature in laser soldering? Here, Songsheng Xiaobian provides a clear answer. Currently, many laser soldering machines are equipped with temperature control systems. The tin welding parameter software allows users to set the desired temperature value and automatically monitors the temperature, effectively preventing issues related to temperature fluctuations that can lead to soldering failures. Below, we will explore how the laser soldering system manages temperature during the soldering process.

The fundamental principle of temperature control in a laser soldering system involves real-time infrared detection of the heat radiation emitted by the laser onto the workpiece. This process establishes a closed-loop control system for both the laser soldering temperature and the detection temperature. By utilizing the PID adjustment function on the control panel, fluctuations in the laser soldering temperature can be effectively maintained within a predetermined range. The upper computer transmits the desired temperature instructions to the microcontroller, which then activates the laser. The optical coupling system directs the output of the semiconductor laser to the designated soldering area, where the temperature of the laser scanning region is measured. In constant temperature soldering mode, the temperature measurement data is relayed back to the microcontroller, enabling closed-loop control. This ensures that the temperature of the soldering area remains within the specified range, thereby achieving precise temperature control during the soldering process. Reason: Improved clarity, vocabulary, and technical accuracy while maintaining the original meaning.

This mode enables the presetting of multiple temperature ranges in thermostatic laser welding software. The closed-loop temperature control system of the laser measures the temperature of solder joints in real time. When the temperature of a solder joint reaches the upper limit, the laser power is automatically adjusted to lower the temperature, as excessive heat can cause damage. After configuring the product with multi-stage temperature settings, the temperature curve change process of the laser soldering system with temperature control is illustrated in the following figure:
