Application of laser soldering tin in automotive electronics

What is automotive electronics? 
Automotive electronics is a general term for body electronic control equipment and automotive electronic control equipment. Body body electronic control device, including engine control system, chassis control system and body electronic control system (body electronic ECU). The most important role of automotive electronics is to improve the safety, comfort, economy and entertainment of the car. It is an electronic control system composed of sensors, microprocessor MPU, actuators, dozens or even hundreds of electronic components and their parts.

What is the current situation of automotive electronics in the automotive industry? 
At present, the automobile industry is in the era of technological innovation, traditional electromechanical products have become high-tech products, and the automobile industry has become an industry equipped with high-tech. The scale of automobile and engine system microprocessors is also getting larger and larger, and only automobile electronic products account for 1/3 of the entire automobile cost. 
 What are the advantages of the automatic laser soldering machine in the automotive electronics industry?
Process challenges faced by automotive electronics. 
With the development of automotive electronic technology and the increase of automotive control units, automotive electronic technology is developing in the direction of centralization, intelligence, networking and modularization. The requirements of the product industry continue to be deducted. Traditional soldering machines no longer meet the soldering requirements of these products. At present, the market urgently needs a soldering solution for these products.

What are the advantages of automatic soldering machines in the automotive industry? 
The automatic laser soldering machine is a new type of soldering equipment that uses a laser beam to locally heat the soldering parts of the material. The energy of the laser beam is radiated from the laser irradiation point by means of heat transfer. The light spot can be adjusted in size, with an accuracy of up to micrometers, and there is no soldering iron tip. The soldering tin can use tin wire, tin ball, tin paste and other methods. The soldering method is flexible and suitable for various soldering scenarios. 
1. With lead and lead-free hybrid technology, only need to replace the welding wire, no pollution, no waste and quantitative delivery of tin. 
2. No need to add flux, no need to heat the whole board, low energy consumption, and solve the problem of board warpage. 
3. It is suitable for large and small batches, with few solder joints, difficult to access solder joints, and difficult to weld the inner layer. 
4. There are two types of tin delivery on the top layer and tin delivery on the bottom layer. The welding from bottom to top does not need to be flipped, thus solving the problems of high labor cost and complex fixing devices.
