Abstract: A laser soldering device includes a laser source, a lens group, a temperature sensor, and a feedback controller. The laser source emits a laser beam, which is power-adjustable, according to a control signal. The temperature sensor receives infrared rays radiated when the laser beam is irradiated to the soldering point to detect the temperature of the soldering point, and correspondingly outputs a sensing signal according to the detected temperature. When the detected temperature falls into a first temperature range based on a target temperature, the feedback controller executes a PID algorithm to calculate a predicted error value according to an error value between the detected temperature and the target temperature. The feedback controller controls the laser source according to the predicted error value, and adjusts the power of the laser beam accordingly, so that the detected temperature can be substantially equal to the target temperature.

Abstract: A multi-beam soldering system includes a multi-beam scanner, a sensor, and a controller. The multi-beam scanner generates at least a first beam and a second beam, and guides the first beam to a first element of a soldering zone and guides the second beam to a second element of the soldering zone. The sensor detects a first temperature of the first element and a second temperature of the second element simultaneously during soldering process. The controller adjusts the parameters of the first beam and the second beam under the condition that the first temperature is substantially different from the second temperature.
