Description

Functions
Precise local soldering: Selective tin spraying soldering is performed for specific solder joints on PCBs, such as plug-in components and irregular components, to avoid sensitive components and reduce thermal damage.
Suitable for small batch production: The desktop design is flexible and portable, suitable for research and development sampling, small batch and multi variety SMT production line soldering, and reduces the cost of changing lines.
Improving welding quality: Compared to manual welding, the amount of solder can be controlled, the consistency of solder joints is high, reducing virtual soldering and continuous soldering defects, and ensuring product reliability.
