1 This product is a welding module, which can be flexibly installed on the standard platform machine or customized machine to realize the process of laser tin ball tin spraying;

 

2 includes the installation of mechanical unit and independent electric control box. The mechanical part is installed on the z-axis mechanism of X-Y-Z platform, and the electrical is connected with the I / O communication of main console;

 

The control mode of 3 is simple. It can complete a series of actions such as ball dropping, laser output and ball spraying with only a few IO points.

principle of laser solder ball welding module

it is a new ball planting technology that uses laser to heat the tin ball and spray it to the position requiring ball planting bonding through a certain pressure. It has the advantages of non-contact, no flux, small heat, accurate and controllable solder and so on.

principle:

the tin balls are transported to the welding nozzle one by one by means of mechanical movement. The tin balls are melted by laser irradiation and sprayed onto the weldment under the action of pressure. Since the position of the tin ball and the parameters in the welding nozzle are monitored in real time by the detection mechanism, the starting spraying time of the laser emitter can be accurately controlled, so the welding with high precision and high accuracy can be achieved.

process:

add the tin ball into the tin ball cavity, divide the ball, and separate the tin ball into the guide channel;
The solder ball reaches the end of the nozzle through the guide channel, emits laser melting, pressurizes and sprays it onto the pad to complete the welding.

advantages:

non-contact, no damage to the product;
Helpless flux, no pollution, Wuxi bead residue;
Efficient and fast
