PCB circuit boards laser welding machine in the electronic devices and circuit board assembly and enter the welding station, under the control of the controller, first by the visual device for visual positioning welding position, and then through the wire feed mechanism move the wire to the welding position, laser welding machine laser to welding position, heat, temperature controller to monitor the welding position at the same time, the measurement Wire after laser irradiation temperature.
When the temperature increased to more than welding wire melting temperature, wire feeding agencies began to send wire according to the set speed, at the same time temperature controller to monitor the welding temperature, when the welding temperature is higher than the set temperature, reduce the laser welding machine power output by the controller.
When welding temperature is lower than the set temperature, the increase in laser welding machine output power, makes the welding Always stay in setting temperature area, prevent damage of high temperature components, prevent low temperature, welding can not complete; To sum up, we provides PCB working process principle of laser welding machine is introduced.
