The difference and application of laser soldering machine and fiber metal fiber laser welding machine
Is a laser soldering machine (laser soldering) the same as a metal fiber laser welding machine? Why are the names so similar and are they the same laser device? Can it be universal? Of course not, the metal fiber laser welding machine and the laser soldering machine are just similar in name. In terms of working principle, applicable materials and application industries, there is not much connection. They are two completely independent devices!
metal fiber laser welding machine
1. Operating principle:
Laser welding is a precision welding method that uses a laser beam with high energy density as a heat source. The surface heat diffuses into the interior through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific shape. The molten pool is one of the important aspects of laser material processing applications. It is mainly aimed at the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc.
The main feature of laser soldering is to use the high energy density of the laser to achieve local or small area heating to complete the soldering process. The key to laser soldering lies in the reasonable control of laser power distribution. Although the two use a laser beam as a heat source, there are still differences in the process.
Laser soldering (laser soldering) is a type of laser processing. It uses a laser as a heating source, radiates heating leads (or connection pads of leadless devices), and transfers heat to the substrate through special solder for laser soldering (laser solder paste/tin wire or prefabricated solder sheet). When the temperature reaches the tin solder At the melting point temperature, the solder melts, and the substrate and leads are wetted by the solder to form a solder joint.
2. Applicable materials and application fields:
The materials suitable for the laser soldering machine are SMT post-insertion, welding of temperature-sensitive components, difficult-to-solder components, micro speakers/motors, SMT post-soldering processing of various PCBs, various parts of mobile phones, etc. The laser soldering machine is mainly used in the precision processing of the electronics industry, such as spot welding of PCB boards, spot welding of soldering, electronic connectors, thermal components, etc. USB cable welding, flexible circuit board FPC or rigid circuit PCB board welding, high-precision LCD screen LCD, TFT welding and high-frequency transmission lines, etc.
The welding materials applicable to the metal fiber laser welding machine are die steel, carbon steel, alloy steel, stainless steel, copper and copper alloys, aluminum and aluminum alloys, plastics, etc. metal fiber laser welding machines are widely used in batteries, solar energy, mobile communication, optical fiber communicators, molds, electronic appliances, IC integrated appliances, instrumentation, gold and silver jewelry, precision devices, aerospace devices, automotive industry, motor industry.
- Introduction of special solder for laser soldering machine (laser soldering):
Haohaisheng, as a domestic solder paste manufacturer for laser soldering machine, has developed and applied very successfully earlier. It is used for camera modules, VCM voice coil motors, CCM, FPC, connectors, antennas, sensors, inductors, hard disk heads, speakers. , speakers, optical communication components, thermal components, photosensitive components and other products that are difficult to solder by traditional methods are the research and development objects.
