The working principle of the laser solder ball welding machine is that the solder balls fall into the guide channel and finally stop at the bottom of the nozzle after passing through the precision ball separation device. After being melted by laser heating, it is jetted from a special nozzle and directly covers the pad without additional flux or other tools. Solder ball spray welding is adopted, which has high welding precision and can realize precise welding for the soldering has a temperature requirements or soft board connection welding area. During the whole process, the solder joints are not in contact with the welding body, which solves the electrostatic threat caused by contact during the welding process. The welding yield rate is 99%.

Range of applications for laser solder ball jetting equipment

Products are widely used in the microelectronics industry: such as HD camera modules, mobile phone digital camera soft board connection point welding, precision sound control devices, data line welding point assembly welding, sensor welding. Military electronics manufacturing industry: aerospace high-precision electronic product welding. Other industries: Welding of wafers, optoelectronic products, MEMS, sensor production, BGA, HDD (HGA, HSA) and other high-precision components, and high-precision electronics.

Advantages of laser tin ball welding machine

Laser tin ball welding process:

-Applied to high precision micro tin welding

-Suitable for gold plating, silver, tin, copper welding surface

Advantages of laser solder ball jetting system:

-No rosin residue, free from cleaning

-The tin ball is melted by laser in the nozzle. The laser does not act directly on the solder joint, reducing the probability of scalding the peripheral devices

-Efficient fast

-The size of the tin ball is fixed to ensure the consistency of the solder joint

-Non - contact welding, small thermal effect on welding joints, no splash pollution

Specification of tin ball:

-Accuracy: + / - 3 um

-Tin ball size(optional): 100um-750um
