Applicable materials for solder pads

Features of the XJ-JX300 laser spray solder ball soldering machine:

1. Adopting a fiber laser, highly integrated with the industrial control system in the workbench cabinet, combined with a ball planting mechanism to achieve synchronization between tin ball and laser welding, equipped with a dual station interactive feeding system, the feeding, unloading, automatic positioning, and welding are carried out synchronously, achieving efficient automatic welding, greatly improving production efficiency, and meeting the needs of precision level components such as BGA chips, wafers, communication devices, camera CCM modules VCM enameled coil modules and contact basin frames require soldering with tin, which has a certain range of special applications.

2. Adopting high-precision imported automatic solder ball spraying mechanism, the diameter range of the solder ball is optional, with a minimum diameter of 0.1mm, which is in line with the development trend of integration and precision; The laser tin ball automatic spraying system can spray 7200 points per hour.

3. The solder ball does not contain soldering flux, and the solder ball is melted inside the welding nozzle without splashing during welding.

4. The difference in solder balls is small, and the consistency of solder joints after welding is very high.

5. Welding speed is fast, equipment production capacity is high, and there is no heat impact around the welding point.

6. It has multiple protections and automatic protection functions for multiple tin balls, blocked balls, etc. at once.

Technical parameters of laser spray solder ball soldering machine XJ-JX300:

1. Station: Dual worktable (optional)

2. Laser power: 100W optional

3. Laser wavelength: 10640m

4. Welding method: automatic spraying

5. Working voltage: AC 220V

10. Weight: 1500KG

11. External dimensions: 1560 length * 1200 width * 1500 height

The principle of laser spray solder ball soldering machine XJ-JX300:

The principle is to send the tin ball particles to the nozzle through the ball feeding mechanism, and then laser irradiation will melt the tin ball,

Spray liquid tin onto the surface of the product through nitrogen gas; Tin balls are small particles of pure tin that are not dispersed,

After laser heating and melting, it will not cause splashing, and after solidification, it will become full and smooth without any other process,

For example, subsequent cleaning or surface treatment of the pad. Compared to traditional welding, tin ball laser welding has higher efficiency,

No flux, high consistency in appearance, high welding stability, and minimal thermal impact.

Application of laser spray solder ball soldering machine XJ-JX300:

Microelectronics industry: hard disk heads, high-definition camera modules, mobile digital camera soft board connection welding, precision voice control devices, data cable solder assembly welding, sensor welding. Other industries can be used for welding high-precision components such as wafers, optoelectronic products, MEMS, sensors, BGA, HDD (HGA, HSA), mobile communication, digital cameras, camera modules, etc.
