The Turntable Selective Wave Soldering Machine RS-D2 is a professional-grade offline dual solder pot system engineered specifically for high-volume, high-precision production of small-size PCB assemblies. This advanced soldering equipment features an innovative dual-station synchronous design, enabling parallel processing that significantly increases production throughput while maintaining strict soldering accuracy. By integrating manual feeding, automatic flux spraying, preheating, and automatic soldering into one optimized workflow, this machine ensures consistent quality across large production runs. Each individual solder joint can be programmed via computer-controlled parameter settings, allowing for tailored thermal profiles. With an intuitive operation interface and fully traceable production procedures, the RS-D2 serves as a highly efficient soldering solution for large-scale manufacturing facilities and consumer electronics enterprises looking to upgrade their assembly lines.
Product Advantage
This equipment includes manual feeding station, automatic spraying station, preheating station, and automatic soldering station.
The rosin flux nozzle can move along the XY axis.
There is a soldering furnace, which can move along the XYZ axis, and an N2 protection device is installed in the soldering furnace.
Multiple stations can work at the same time to improve work efficiency.
Product Application
The RS-D2 turntable selective wave soldering machine is engineered for versatility and reliability across a wide range of demanding industries. It is specifically optimized for the mass production of small-size PCBs up to 100×100mm. This makes it an ideal investment for manufacturing facilities with standardized product lines requiring consistent, high-yield outputs. The equipment is widely deployed in sectors requiring stringent quality control, including military electronics, aerospace, medical devices, new energy systems, automotive electronics, communication equipment, home appliance manufacturing, digital product assembly, and stage lighting controls.

Product Operate Guide
This programmable selective soldering machine operates on a reliable industrial PC paired with a motion control card system, supporting multiple soldering modes to adapt to diverse product requirements. Operators can easily configure distinct parameters for each specific solder joint, achieving precise control over soldering height, temperature, and travel speed through the intuitive PC interface. The system allows for flexible programming via direct image, GERBER, or CAD file imports, which eliminates the need for complex manual programming and significantly reduces setup time during product changeovers. All PCB process parameters can be set, saved, and accessed directly on the PC screen. Additionally, the machine features built-in PCB counting, real-time system messaging, and automated alarm functions to ensure complete production traceability. Our technical support provides comprehensive training to ensure operators can master the equipment efficiently.
