Various electronic products have appeared in the assembly of modern automobiles, and the application of electronic technology has become more and more widespread. What follows is the reform of the traditional processing industry. The constant temperature and high speed laser soldering system helps the miniaturization of automotive electronics.
The degree of automobile electronics is regarded as an important indicator of the level of modern automobiles, and it is one of the most important technical measures for developing new models and improving automobile performance. With the continuous improvement of people's requirements for car comfort, safety, and economics, automotive electronic equipment is constantly increasing to meet the expanding needs of system functions, but the space inside the car is limited, so the main direction to resolve the contradiction is to replace the parts The design is as small as possible, and more parts are arranged in a limited space. Therefore, in order to achieve the requirements of energy saving, safety and comfort, manufacturers continuously improve automobile wiring harnesses and connection systems, so that they can effectively reduce weight and achieve functional integration.
After years of efforts, car manufacturers have successfully developed the next generation of miniaturized connection systems, including miniaturized connectors and terminals. For the crimping problem of small wire diameters developed by different wire manufacturers, innovative solutions and test verification methods are also given. Its biggest advantage is that it can significantly reduce the weight of the wire harness. At present, major wire manufacturers have developed various reinforced small-diameter wires. Various innovative processes have been applied to solve the problem of insufficient drawing force of small-diameter wires, such as using copper alloy wires, adding stainless steel wires, etc. Take 40 wires as an example. The total weight of a wire with a diameter of 0.13mm2 is only 28% of a wire with a diameter of 0.5mm2.
At the same time, the rapid increase in automotive electronic equipment is driving the further realization of miniaturization. In particular, the high density and complexity of electronic equipment requires that as many functions as possible be placed in a limited space. Therefore, car manufacturers have developed the next generation of miniaturized products-micro-connected systems, following the market development. Automotive connectors are a component that electrical engineering technicians often contact. Its function is very simple: between the blocked or isolated circuits in the circuit, build a communication bridge, so that the current flows, so that the circuit to achieve the intended function.
Such a compact structure requires less space and places higher requirements on the production process. In fact, this automotive electronic product integrates a variety of demanding production processes. At the same time of industrial technological innovation, it also means that it poses a huge challenge to the traditional processing industry. When the miniaturization of automotive wiring harnesses and connection systems changes, and the requirements for automotive safety continue to increase, the development of laser welding methods will undoubtedly become miniaturization of automotive electronics Important weapon.
Nowadays, the constant temperature high-speed laser soldering system is compatible with the selective soldering in modern reflow soldering processes, and is especially suitable for automotive electronic soldering. The constant temperature and high speed laser soldering system realizes the rapid welding of the welding body through the high-speed deflection of the laser. The matching CCD coaxial positioning system can automatically identify the welding body. It is a laser selective welding specially developed for modern reflow soldering technology. Thus, high-efficiency, high-precision automated production is achieved. It can be used in all SMT application fields. Compared with SMT, it adopts a unique local heating method. When welding an original, it will not have a thermal effect on other components, and it is also suitable for the field of microelectronic connectors, such as ultra-thin coaxial wires and Terminal welding, USB cable welding, flexible circuit board FPC or rigid circuit board PCB welding, high-precision liquid crystal screen LCD, TFT welding, and high-frequency transmission lines can effectively achieve automotive electronics precision processing.
