principle:

the tin balls are divided into one by mechanical movement and transported to the welding nozzle one by one. 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 type, no damage to the product;
• • Helpless flux, no pollution, Wuxi bead residue;
• • Efficient and fast
