In recent years, with the continuous development of the laser industry and the rapid development of laser technology, the laser industry has also moved from an unattainable altar to an all-inclusive industry. At the same time, the emergence of new technologies has also posed a certain threat to traditional industries. It is precisely because of the high reliability and low energy consumption of laser that it can completely replace some traditional industry-specific equipment.
Advantages of wave soldering:
A kind of through-hole component substrate welding has high production efficiency, high degree of automation, precise control of flux injection position and injection amount, precise control of microwave peak height, precise control of welding position, nitrogen protection of microwave peak surface, and control of process parameters of each welding point. optimize. A technology that combines the quick replacement of nozzles of different sizes, the fixed-point welding of a solder joint, and the ordered array welding of through-hole connector pins. The shape of the solder joint can be set to “fat” or “thin” according to the requirements. It is suitable for a variety of preheating modules (infrared, hot air) and the preheating module added above the board, the maintenance-free electromagnetic pump, and the selection of structural materials are fully suitable for the application of lead-free solder. Modular structural design reduces maintenance time, etc.
Disadvantages of wave soldering:
It is only suitable for PCB assembly processes with through-hole designs. SMT and CABLE WIRES are not applicable, so the scope of application is relatively limited. Since flux needs to be used during welding and tin slag is generated, the later production cost is higher.
Laser soldering features:
1. Card control of multi-axis servo motors with high positioning accuracy
2. The laser spot is small, and there are advantages in welding devices with small pads and spacing.
3. The solder joints have good consistency, beautiful appearance and round shape.
4. No waste of tin welding slag and flux, low production cost
5. The types of products that can be welded are SMD, PTH, and cables
6. High tin penetration rate (more than 90%) and easy to control
7. Easy to automate
8. The amount of wire feeding can be accurately controlled, and the usage of consumables can be easily controlled.
9. Non-contact welding, no mechanical stress, no static electricity hazard
