Product Detail

The laser welding machine is developed for soldering PCBA joints in low-voltage terminal electrical products. It integrates a laser soldering unit, automatic solder-wire feeding system, vision positioning and inspection system, four-axis robot, precision XY soldering platform, and slat-chain conveying and sorting system.

Without manual intervention, the equipment automatically completes loading, code reading, positioning, inspection, laser soldering, reject removal, unloading, and solder-residue cleaning, significantly improving production efficiency and product consistency.

Highlights

Non-Contact Precision Soldering

The laser beam replaces a conventional soldering iron tip, eliminating mechanical stress and preventing process variation caused by tip wear.

Rapid Localized Heating with Minimal Heat-Affected Zone

Concentrated energy heats each solder joint within milliseconds, minimizing thermal impact on nearby components, copper traces, and plastic housings. It is suitable for PCBAs containing heat-sensitive components.

Stable and Reliable Solder-Joint Quality

Diffusion between the solder and base metal forms a strong alloy layer, providing excellent electrical conductivity, tensile strength, and impact resistance, with full, bright joints free from cold soldering and missed soldering.

Flexible for Small and Densely Spaced Joints

Precise control of laser position and energy supports different solder-point layouts for 2P, 3P, and 4P products, particularly for small and densely arranged solder joints.

FAQ

01、Is switching product specifications troublesome? How long does it take?

Not troublesome. Changeover mainly involves manual replacement of the positioning block; changeover time is ≤ 10 min, no hardware modification is required—simply adjust the program and parameters to switch to different spot layouts.

02、What are the advantages over traditional welding methods?

It uses non-contact laser soldering, with no mechanical stress and a minimal heat-affected zone, suitable for co-board welding of thermally sensitive components, delivering high solder-joint consistency and stable, reliable quality.

03、How is welding quality ensured? How are defective products handled?

It integrates vision positioning + code reading + pre-weld inspection, with real-time monitoring of the welding process; defective products are automatically picked by the robot to a designated area and strictly isolated from good products, with a defect rate ≤ 1%.

04、What safety protection measures does the equipment have?

It is equipped with multiple protections including an electrically interlocked safety door lock (stops when opened), low-noise design, and light-force enclosure opening/closing (≤ 1 kg), complying with EHS requirements.
