With the development and iteration of laser technology, many industries such as electronic and mechanical parts, precision electronic products, household appliances, high-end fields, electronic components and so on are inseparable from laser technology. Laser soldering technology with its non-contact solder, fast and efficient, high precision, beautiful weld, infinite product shape, easy to control, strong adaptability and other advantages, widely used in automobile, electronics, steel, aerospace, shipbuilding and other industries.

Laser tin ball welding is a kind of welding method in which the tin ball is placed in the mouth of the tin ball and melted by laser heating after falling onto the pad and wetting the pad. The tin ball is non-dispersed pure tin small particles, because the tin ball does not contain flux, laser heating melting will not cause splash, full and smooth after solidification, no follow-up cleaning or surface treatment on the welding disc additional processes. And the amount of tin is constant, the ball welding speed is fast, high precision, especially suitable for HD camera module and precision voice control devices, data line solder joint assembly and other small plate and enamented wire solder welding.

The tin ball jet welding machine includes three working modes: single position, double position and three position. The process of heating and melting drops is fast and can be completed within 0.2s. The tin ball can be melted in the welding nozzle without spatter phenomenon. No flux, no pollution, maximize the life of electronic devices. The minimum diameter of the tin ball is 0.1mm, in line with the development trend of integration and precision, but also through the selection of the size of the tin ball to complete the welding of different solder joints. High standard repeated positioning accuracy to ensure the consistency and stability of product welding, with CCD positioning system can meet the needs of mass production line. In addition, the equipment is easy to operate, no tool contact in the welding process, avoid tool and device surface contact caused by device surface damage, meet the requirements of precision electronic components welding, but also help customers greatly improve production capacity.

Laser tin ball soldering machine adopts non-contact heating, the use of laser as a heat source, nitrogen as a power to melt the tin ball ejection, so as to achieve the whole process of solder is non-contact, it can be more accurate control solder solder amount and solder height, to ensure that no splash, no residue and no cleaning in welding.
