The difference between laser soldering robots and robot solders is that most of us have learned about the traditional robotic soldering iron soldering technology and become the popular main soldering equipment in the current automated soldering equipment market. However, as electronic products are increasingly miniaturized, the stability of automated soldering becomes more and more demanding, and traditional solder robots have already failed to meet user needs. The new automatic soldering technology laser soldering machine was born and became the market for automated soldering equipment. a new type of technology has attracted much attention. Understanding the use of laser soldering technology can give full play to the advantages of laser soldering. Let's take a look at the differences in the soldering technology between robot solder and laser solder.

What is the difference between laser soldering and robot soldering soldering?

The process of laser soldering and robot soldering soldering is divided into three basic steps: preheating, heating for soldering, and post-heating after soldering. Although the basic procedures for robotic soldering and laser soldering are the same, there are different ways to provide heated soldering.

Welding temperature regulation?

Temperature is critical during welding. The state of solder composition changes due to rising or falling temperature conditions. If the temperature is low, the solder is not completely soldered and the solder wire is not melted. If the temperature is too high, the solder may be overheated and the device may be burned. Therefore, it is difficult to achieve the strength and reliability of welding without performing welding under proper temperature conditions. Moreover, when the temperature is not appropriate, the flux will change the flow direction due to the temperature. When heated at the proper temperature, the flux first flows to the welding site, and the surrounding oxides and dirt are removed, so that the solder can be better joined. If heated too much, the solder will stop the flow of flux that aided flow. In addition, excessive heating can damage the substrate, causing many problems such as cracks inside the substrate that cannot be judged by the naked eye.

Laser Solder Features:
1. Without contact, the spot energy is concentrated and the heat affected area is small, which will not cause a burden on the substrate.
2. Effectively heat and provide solder, automation is expected to achieve stable welding.
3. The laser has a long life, low power consumption, and low maintenance costs.
4. No iron tip loss.
5. Can complete the iron head, can not enter the narrow position and welding of dense assembly.
6. High maintainability.

We can observe that during soldering, laser solder throws away the traditional soldering iron pattern. First, the laser is used to irradiate the soldering site so that the irradiated site can begin to heat up. When the irradiated area is heated to melt the solder wire, the required solder wire is fed to provide solder. Melting and forming. Complete the entire welding process.

We have seen that the method of soldering the iron tip and heating the two are different, but they often complement each other during work. Since the robot soldering iron solder heat transfer through the soldering iron, the laser soldering is heating the irradiated parts. So if the temperature of the soldering tip is not enough when soldering the soldering iron of the robot, it can be raised by the laser that can be irradiated by the spot. Of course, because the continuous irradiation may cause the temperature of the tip to be too high, it is necessary to pay attention to the adjustment of the irradiation intensity and time.
