In recent years, with the rapid development and upgrading of electronics, digital and terminal class industries, more and more important parts of the product towards the trend of miniaturization or even miniaturization, the demand for highly refined processing methods is increasing, as a new technology for precision welding process, laser soldering technology has ushered in rapid development.
Compared with the traditional manual soldering, automatic soldering iron soldering equipment, laser soldering equipment with heating and cooling speed, high degree of automation, low power consumption, less consumables, long life, high utilization rate of solder, high efficiency of soldering, good welding effect, etc., in the automotive electronics, semiconductor, consumer electronics, camera modules, PCB boards, medical machinery, aerospace and other manufacturing fields are more widely used.
Laser soldering market is huge
Laser soldering is an emerging technology for PCB board welding, in the context of the rapid development of domestic science and technology and the continued transformation of existing processes, PCB board applications are expanding, which in turn drives its market demand is increasing, the output value of PCB industry in mainland China reached $44.31 billion in 2021, an increase of 24.6% year-on-year. Solder is a necessary part of the PCB production process, laser soldering equipment as an important carrier of soldering technology, and its market demand is increasing.
In the future, as the domestic PCB, semiconductor and electronics industries upgrade towards high-end and high precision, their requirements for precision soldering technology will continue to upgrade, laser soldering equipment is expected to continue to increase market penetration by virtue of its unique advantages.
Blue light laser advantage is obvious
Precision tin soldering is mainly concentrated in the field of microelectronics, such as very fine coaxial line and terminal welding, micro plug-in components welding, USB line welding, soft circuit board FPC or hard circuit PCB board welding, high-precision LCD, TFT welding and high-frequency transmission lines and other applications. In these applications, laser soldering becomes an effective solution to replace the traditional soldering iron welding, which can greatly improve the production efficiency and quality of batch products. At the same time, in the traditional PCB board plug-in components, wires, terminals and other occasions can not use SMT for automatic soldering, laser soldering also has a good application effect.
At present, the market laser soldering light source is divided into two kinds of infrared and blue light, including infrared light source wavelength 808-980nm, blue light wavelength 450-455nm. hard science academy developed a special laser tin welding blue semiconductor laser, wavelength 455nm, using fiber output and free space output two ways, can be used for copper, aluminum, resin-based PCB board soldering applications, compared to infrared The laser welding process is more stable, with full solder joints and no defective fried tin or splash.
At present, the market precision soldering project solder joint minimum in 0.2mm or so, hard science academy blue laser temperature control soldering system is for this kind of precision soldering developed products, with non-contact, high precision, real-time closed-loop temperature control, low temperature thermal effect of small impact, etc., can be applied to the traditional soldering iron soldering and other processes can not be competent occasions, especially for positioning accuracy, temperature is highly sensitive to the high precision soldering processing occasions.
Blue laser market is growing rapidly
With the technological breakthroughs in industries such as new energy and electric vehicles, as well as the continuous import of non-ferrous metal welding, cladding, precision soldering and other applications, the blue laser market is rapidly expanding and growing, becoming a new hot spot in the field of optoelectronics.
