Laser Soldering Device with Trailing Solder Wire and Laser Soldering Method
Simple SummaryContent extracted from patent full text and abstract with AI.
This patent describes a laser soldering device and method in which at least two laser beams and a solder wire feeding mechanism are coordinated. The apparatus directs a leading (first) laser beam and a trailing (second) laser beam onto a workpiece in the direction of processing. The solder wire is supplied in such a way that it follows after the application of the second laser beam on the workpiece, allowing precise and controlled soldering.
Use CasesContent extracted from patent full text and abstract with AI.
- Automated soldering in electronics manufacturing
- Precision joining of metallic components in automotive and aerospace industries
- Soldering of complex or delicate components requiring exact heat control
- Manufacturing of circuit boards and microelectronic devices
BenefitsContent extracted from patent full text and abstract with AI.
- Improved precision in soldering through controlled timing of laser beams and solder wire feeding
- Reduced risk of thermal damage to sensitive components due to focused and sequential laser heating
- Enhanced process automation and consistency in mass production environments
- Higher quality solder joints with less manual intervention
