Tin Ball Laser Welding
After being heated and melted by a laser, the solder balls are ejected from the special nozzle and directly cover the pads. No additional flux or other tools are needed. It is very suitable for processing that requires temperature or soft board connection welding area. During the entire process, the solder joints and the welding body are not in contact, which solves the electrostatic threat caused by contact during the welding process.
Compared with traditional technology, laser solder ball welding has the following advantages
- The laser processing precision is high, the laser spot is small, the processing time can be controlled by the program, and the precision is higher than the traditional process method. It is suitable for the soldering of tiny precision parts and the places where the soldering parts are more sensitive to temperature
- Non-contact processing, no static electricity caused by welding, can be processed in conventional ways that are not easy to weld
- A small laser beam replaces the soldering iron tip, and it is also easy to process when there are other interference objects on the surface of the processed part
- Local heating, small heat affected zone; no electrostatic threat
- Laser is a clean processing method, simple maintenance, convenient operation, and good stability of repeated operation
- The heating speed is fast and the positioning is accurate, which can be completed in 0.2 seconds
- The tin ball diameter can be as small as 50μm, suitable for high-precision welding
- The yield rate of solder is higher than that of ordinary automatic soldering machines
- With a visual positioning system, it is suitable for assembly line production
Wire Laser Soldering
Tin wire laser welding is suitable for conventional PCB / FPC pin, pad wire and other products with large pad size and open structureIt is difficult to realize the laser welding of tin wire for the products which are hard to be delivered by wire feeding mechanism and easy to burn around
Paste Laser Soldering
Solder paste laser welding process is suitable for conventional PCB / FPC pin, pad line and other types of products
The processing method of solder paste laser welding can be considered if the precision requirement is high and the manual method is difficult to realize
